Unit 18 · Child Development and Care

Put a four-month-old on her stomach on a blanket and watch. She pushes up on her forearms, lifts her head, holds it steady and looks around. A month earlier her head wobbled. A month from now she may roll over. This is physical development: the growth of the body and the child’s gaining control over its muscles. It does not happen at random. Control comes first to the head and neck, then the trunk, then the legs. Doctors call this head-to-toe growth. Control also comes first to the center of the body and moves outward: shoulders before hands, hands before fingers.

Big movements that use the large muscles are gross motor skills. In the first year they arrive in a fairly fixed order. Many babies hold their head steady at about 2 to 4 months, roll over at about 4 to 6 months, sit without support at about 6 to 9 months, pull up to stand at about 8 to 12 months, and walk alone somewhere between about 9 and 15 months. Some babies crawl at 7 to 10 months; some scoot on their bottoms; some skip crawling entirely and go straight to walking. The order is what matters, not the calendar.

Small movements of the hands and fingers are fine motor skills. A newborn’s fist closes on your finger by reflex. At about 4 to 6 months a baby rakes at a toy with the whole hand. Between about 9 and 12 months the pincer grasp appears: thumb and forefinger together, picking up one piece of cereal. That grasp is the foundation of everything that comes later. Many children scribble at about 15 to 18 months, stack a small tower of blocks at about 2, copy a circle at about 3, and write some letters of their name at about 5.

Every one of those numbers is a range, and the late end of a range is still on time. A child who walks at 10 months is not ahead; a child who walks at 14 months is not behind. The pediatrician’s rule in the story is the rule here: watch the order, watch the range, and watch whether the child keeps gaining new skills. A child who stops gaining skills, or loses a skill she had, is the child to ask about.

Hide a toy under a blanket in front of a five-month-old and she looks away, as if the toy has stopped existing. Do the same thing in front of a nine-month-old and he pulls the blanket off. Nothing about his eyes changed; his mind did. This is cognitive development: the growth of thinking, memory, attention, problem solving and understanding. The nine-month-old has learned object permanence, the idea that things go on existing when you cannot see them. It usually shows up somewhere between about 6 and 10 months, and it is why peek-a-boo suddenly becomes the funniest game in the world.

Infants learn through their senses and their movements. A baby who drops a spoon from the high chair forty times is not being difficult. She is running an experiment: every time, it falls, and every time, someone picks it up. That is cause and effect, and she is learning it the only way she can. Toddlers add memory and imitation. A two-year-old who feeds a doll with a spoon is copying something she saw yesterday and holding it in her head, and she is starting to use one thing to stand for another. That is the beginning of symbolic thinking, which is also the beginning of language and pretend play.

Preschoolers, about 3 to 5, think in a way that is powerful and lopsided. They can sort by color, count a small group of objects, follow a three-step direction and tell you what comes next in a familiar story. They also believe the taller glass holds more juice even when they watched you pour the same juice into it, and they assume everyone sees what they see. That last one is called egocentrism. It is not selfishness. It is a stage of thinking that most children move past by about 6 or 7, when they begin to reason more like adults, hold rules in their heads and understand another person’s point of view.

The principle: children are not small adults with less information. At each stage they think differently, and the job of an adult is to meet the thinking where it is. You do not reason with a two-year-old about why the cup must stay on the table; you move the cup. You do not expect a four-year-old to share without being asked; you set up the turn. Knowing the stage prevents most of the frustration on both sides.

A newborn cries. Someone comes, picks her up, feeds her or changes her or simply holds her. It happens a hundred times a week. Each time, without any words, the baby learns something: when I need help, help comes. That lesson, repeated for months, builds attachment, the deep bond between a child and the person who cares for her. It is the foundation of social development, learning to relate to other people, and emotional development, learning to feel, understand and manage feelings. A baby whose needs are met reliably learns to trust. A baby who is left to cry for long stretches learns that the world does not answer.

Attachment has visible milestones. Many babies smile at a face by about 2 months. By about 6 to 9 months many show stranger anxiety, going quiet or crying when someone unfamiliar picks them up. Separation anxiety, protest when the caregiver leaves, often peaks between about 10 and 18 months. Both are signs that attachment is working: the baby knows who her people are. Toddlers use the attached adult as a base, wandering off to explore and running back to check in. A toddler who never checks in, or who is equally happy with any adult, is a child to watch.

Every child also arrives with a temperament, an inborn style of reacting. Some babies are easy to soothe, settle into routines and greet new things with interest. Some are slow to warm up, hanging back before joining. Some are intense, with big reactions to noise, hunger, change and joy. None of these is a flaw, and a temperament is not a personality problem to fix. The adult’s job is to fit the care to the child: extra warning before a change for the slow-to-warm child, a calm room for the intense one.

Emotional skills grow in a rough order. Toddlers feel everything at full strength and cannot yet manage it, which is what a tantrum is: a feeling bigger than the child’s tools. Preschoolers learn to name feelings, mad, sad, scared, and to use words instead of teeth. School-age children learn to wait, to lose a game without falling apart, to keep a friend through a disagreement. The adult teaches all of this mostly by example: naming feelings out loud, staying calm, and coming back after a hard moment.

A newborn arrives with reflexes and not much else. Touch her cheek and she turns toward it, rooting for milk. Put a finger in her palm and she grips. Startle her and her arms fly out. She sleeps 14 to 17 hours a day in short stretches and eats every 2 to 3 hours. She can see about 8 to 12 inches, roughly the distance to the face of whoever is feeding her, and she prefers faces to anything else. Infancy, the first year of life, begins here and ends with a child who walks, points, and says a word or two.

By about 2 months many babies smile at a face and coo. At about 4 to 6 months they babble, rolling out strings like "ba-ba-ba," laugh, roll over, and reach for things. Around 6 months many can sit with support and are ready to start solid foods alongside milk. At about 6 to 9 months they sit alone, pass a toy from hand to hand, and show stranger anxiety. Between about 9 and 12 months many crawl, pull to stand, cruise along furniture, use the pincer grasp, wave, point, respond to their name and say a first word, often "mama," "dada" or "ball."

The caregiver’s work in this year is three things. Respond: pick the baby up, feed her when hungry, change her when wet, and do not worry about spoiling; an infant cannot be spoiled by being answered. Protect: put her on her back to sleep, on a firm flat surface with nothing else in the crib, never shake her, and keep her out of the danger zone of hot liquids, small objects and unfenced stairs. Talk: narrate what you are doing, name what she looks at, read to her from the first months. The number of words a baby hears in the first year shapes the number of words she will say.

What to bring to the doctor in the first year: a baby who does not respond to loud sounds, does not smile at people by about 3 months, does not reach for things by about 6 months, cannot sit with help by about 9 months, or does not babble, point or respond to her name by about 12 months. Any single one may mean nothing. Checkups exist so a professional can look.

A 20-month-old wants to put on her own shoes. It takes six minutes and the shoes end up on the wrong feet. Her father wants to do it in ten seconds. This small standoff is the whole of toddlerhood. A toddler, about 1 to 3 years old, is discovering that she is a separate person with her own will, and she wants to use it. "No" and "me do it" are not defiance. They are the sound of a self forming. The adult who understands that saves himself two years of arguments.

The body: many toddlers walk well by about 15 months, run by about 2, climb stairs holding a hand, kick a ball, and by 3 pedal a tricycle and jump with both feet. Fine motor: scribbling, stacking a few blocks, turning pages, using a spoon with spills, and by about 3 drawing a circle and dressing with help. The mind: pretend play begins, simple puzzles, sorting shapes, following two-step directions. Toilet training readiness usually appears somewhere between about 18 months and 3 years, and pushing it before the child shows signs of readiness usually makes it take longer.

The words: many toddlers say about 50 words by 2 and put two words together, "more juice," "daddy go." By 3 many speak in short sentences that a stranger can mostly understand. The feelings: this is the age of the tantrum. Toddlers want two things at once, cannot wait, cannot explain, and have no brakes. The caregiver provides the brakes from outside: a calm voice, a short clear limit, a choice between two acceptable things, and a body that stays close while the storm passes.

The rule for toddlers is autonomy within safety. Childproof the space so that most of what she can reach is allowed, and "no" is saved for the few things that matter. Offer real choices: the red cup or the blue cup, not "do you want to get dressed?" Give warnings before a change: "two more slides and then we go." Expect messes, expect repetition, and expect to hear the same book read forty times. That is not stubbornness; it is how a toddler learns.

Ask a four-year-old why the sky is blue and be ready for the next question, and the one after that. The preschool years, about 3 to 5, are the age of "why." A preschooler can now hold ideas in his head, talk about things that are not in front of him, and play a game with rules that last more than a minute. He is also still egocentric, still thinks in pictures more than logic, and still cannot always tell what he wished from what happened. When he says the dog broke the lamp, he may half believe it.

The body: by 4 many preschoolers hop on one foot, catch a bounced ball, climb a playground ladder, and by 5 skip and swing themselves. Fine motor: cutting with child scissors along a line, holding a crayon with fingers instead of a fist, copying a square, drawing a person with a head and a few parts, and by 5 writing some letters. The mind: counting to 10 or beyond, naming colors, sorting by size, following three-step directions, understanding "same" and "different," and retelling a story in order. Speech is mostly clear by 4 and fully understandable by 5.

Socially this is the age when play changes shape. Two-year-olds play beside each other. Three-year-olds begin to play with each other, and by 4 or 5 many can plan a game together, assign parts and argue about the rules, which is a skill in itself. Sharing does not come naturally; it is taught by setting up turns and using a timer. Friendships form and break by the hour. Fears appear, of the dark, of dogs, of the drain in the bathtub, and they are real to the child even when they are not real to the adult.

The caregiver’s tools: answer questions honestly and briefly, then let the child ask the next one. Give real jobs, setting the table, feeding the cat, sorting laundry by color, because a preschooler who is trusted with a task learns initiative, the willingness to start things. Read every day. Limit screens and choose slow ones. Set a few clear rules and keep them the same every time. When he lies about the lamp, skip the trial: "The lamp is broken. Let’s clean it up together, and next time tell me right away."

A nine-year-old comes home, drops her backpack and announces that she is never going back to school because Jasmine sat with someone else at lunch. Twenty minutes later she is on the phone with Jasmine, laughing. Welcome to the school-age years, about 6 to 12. The child now lives in two worlds: the family and the peer group, and the second one grows every year. She is also becoming capable in a way that surprises adults: she can read for information, keep a promise, follow a recipe, remember a schedule and argue a point with logic.

The body grows steadily, about 2 to 3 inches a year, with the growth spurt of puberty beginning for some children toward the end of this stage, often earlier for girls than for boys. Coordination improves: real sports, bike riding, handwriting that others can read, cooking with supervision, sewing a running stitch. The mind takes the big step the preschooler could not: logical thinking about concrete things. A seven-year-old knows the juice is the same amount in the tall glass. A ten-year-old can plan a project in steps, understand another person’s point of view, and tell a fair rule from an unfair one, loudly.

Socially, friendships deepen and become more about loyalty and shared interests. Belonging matters intensely, and so does being good at something. The main task of these years is competence: the feeling of being able to do real things well. Children who find something they are good at, a sport, an instrument, drawing, reading, cooking, carry that confidence into the harder years ahead. Children who mostly hear what they cannot do learn to expect failure. The adult’s job is to notice effort and specific progress, not just results.

What to watch: a child who has no friends at all over a long stretch, who suddenly refuses school, whose sleep or eating changes sharply, who stops doing things she loved, or who has bruises or fears she cannot explain. Any of these is a reason to ask gently and, if the answer worries you, to bring in a counselor, a doctor or, when abuse is possible, the people whose job it is to protect children. Most of the time, the nine-year-old is back on the phone in twenty minutes. Being available is the skill.

Watch a three-year-old with a cardboard box for twenty minutes. It is a car, then a house, then a boat, then a hat. She climbs in and out (gross motor), folds the flaps (fine motor), decides it is a boat and needs a paddle (symbolic thinking), invites her brother aboard and assigns him the job of shark (social), and cries when the box tears and then recovers (emotional). Nobody taught her any of this. Play is the way children practice every domain at once, and it is not a break from learning. It is the learning.

Play changes shape with the stage. Infants play with their senses and with you: peek-a-boo, rattles, mirrors, being bounced. Toddlers do parallel play, sitting beside another child, each doing their own thing, occasionally grabbing. Around 3 children start playing together, and by 4 or 5 they plan games with parts and rules. School-age children add organized games, collections, building projects and long pretend stories that continue for days. Rough-and-tumble play, chasing and wrestling, is normal and useful as long as everyone is still laughing.

The best toys are the ones that do the least. A toy that sings and lights up when a button is pressed does one thing. Blocks, play dough, dress-up clothes, a doll, crayons and paper, a set of plastic cups, a pile of leaves, a cardboard box: these are open-ended, they can be a hundred things, and the child supplies the ideas. Match materials to the age. Under 3, nothing that fits through a toilet-paper tube, because it can be swallowed or choked on. Preschoolers can handle small pieces with supervision. Check every toy for loose parts, sharp edges and long cords.

The adult’s role in play is mostly to set the stage and get out of the way. Give time, at least an hour of unstructured play a day for a preschooler, and space, and materials, and then let the child lead. When you do join, follow: if she says the block is a phone, it is a phone. Ask open questions, "what happens next?" rather than quizzing, "what color is that?" And do not fix the lopsided tower. The falling is the point.

A father changes a diaper and narrates the whole thing. "Now the wipe, it’s cold, isn’t it? Now the clean diaper. Now the snaps, one, two, three." The baby is four months old and understands none of it. She is also learning all of it. Language development runs on input: the number and variety of words a child hears, spoken directly to her, in a warm voice, about what is happening right now. Television and background talk do not count nearly as much. A face, a voice and a thing to look at together is how the wiring gets built.

The milestones, as ranges: cooing at about 2 months; babbling at about 4 to 6 months; responding to her own name at about 6 to 9 months; first words at about 10 to 14 months; about 50 words and two-word phrases by about 2; short sentences and about 200 to 300 words by about 3; mostly clear speech that a stranger understands by about 4. Understanding runs ahead of speaking the whole way. A one-year-old who says three words may understand fifty. A child growing up with two languages may say fewer words in each at first, and that is not a delay; count the words in both languages together.

What helps: talk about what the child is looking at, not what you want her to look at. Expand what she says: she says "dog," you say "yes, a big brown dog." Read every day and let her turn the pages, point, and hear the same book many times. Sing. Wait: after you ask something, count to five in your head before filling the silence. What does not help: correcting pronunciation ("say it right"), quizzing, or talking baby talk instead of real words. "Baba" is fine from the baby; "bottle" is what she needs to hear from you.

Language is the domain where early help matters most, because the years before 5 are when the brain is most ready for it. A child who does not babble by about 9 months, has no words by about 16 months, has no two-word phrases by about 2, or loses words she once had, should have her hearing checked and be seen by a doctor. Hearing is the first thing to test; a child who has had many ear infections may simply not be hearing clearly. Speech therapy, started early, is short and effective. Waiting to see is the one thing not to do.

In a kindergarten class of twenty, one child reads chapter books and one is still learning letters. One runs faster than anyone and cannot sit through a story. One speaks three languages and one has a stutter. One uses a wheelchair, one wears hearing aids, one has an IEP for autism and needs the schedule on the wall to get through the day. Every one of them is developing. The ranges in this chapter describe what many children do. They do not describe what every child must do, and a child who is outside a range is not a lesser child. He is a child whose path is different and who may need different support.

A developmental delay means a child is reaching milestones noticeably later than the usual range in one or more domains. Sometimes it resolves on its own. Sometimes it is the first sign of a disability, a lasting condition that affects how a child moves, learns, communicates or relates. Cerebral palsy affects movement. Down syndrome affects learning and often speech. Autism affects communication and social interaction, often with strong interests and sensitivity to sound and touch. Hearing and vision loss affect everything downstream of them. None of these is caused by anything a parent did, and none of them is a reason to expect less love, less play or less joy.

What to do when something seems off: first, write down what you see, with dates. "Does not respond to name, 14 months, three tries today." Second, tell the doctor, plainly and early; do not wait for the next scheduled checkup if the concern is real. Third, know that help exists and is free to ask for. In the United States, children under 3 with delays can be evaluated through their state’s early intervention program at no cost to the family, and children 3 and older through the public schools. The earlier support starts, the more it helps. Waiting to see is the most common mistake and the most costly one.

The principle for anyone who cares for children: know the ranges so you can relax about what is normal, watch the order and the direction, and when a child loses a skill, stops gaining skills or is well past the late end of a range, speak up, kindly and without blame. Then keep doing what you did before: talk, play, read, respond and enjoy the child who is actually in front of you. Mateo’s pediatrician did not say "he is fine." She said "he is on time, and here is what I am watching." That is the whole skill.

A three-year-old throws a cup of milk on the floor. One adult yells, grabs her arm and puts her in a chair facing the wall for ten minutes. Another adult says, "Milk stays in the cup. Here’s a towel; let’s wipe it up," and hands her the towel. Both adults want the same thing: no more milk on the floor. Only the second one is teaching it. Guidance is everything an adult does to help a child learn how to behave. Punishment is making a child suffer for what she already did. The first builds a skill. The second builds fear, and fear stops working the moment the adult leaves the room.

The case against spanking is not about being soft. Decades of research have found that children who are hit are more aggressive, not less, and are no better behaved over time. Hitting teaches, very clearly, that a bigger person may hit a smaller one when angry. It also damages the trust that makes every other kind of guidance possible. Yelling and shaming do a milder version of the same harm. And shaking a baby, ever, for any reason, can cause permanent brain injury or death. A crying baby who cannot be soothed goes in the crib on his back, safe, while the adult steps out to breathe.

Guidance starts with expectations that match the age. A one-year-old cannot remember a rule from yesterday. A two-year-old cannot share. A three-year-old cannot sit still for a forty-minute dinner. A four-year-old cannot always tell wishes from facts. Most "misbehavior" in young children is a child doing exactly what a child that age does, in a situation that was set up for an adult. Half of guidance is changing the setup: the fragile thing goes on a high shelf, dinner is twenty minutes, the walk to the car starts with a two-minute warning.

The other half is a small set of tools, taught in the next two lessons: routines, choices, redirection, and natural and logical consequences. Behind all of them is one attitude. The adult is calm, the adult is kind, and the adult means it. A limit stated once in a quiet voice and kept every time is worth more than a threat shouted ten times. Children test limits to find out if they are real. The answer should be boring: yes, every time.

Bedtime at the Okafor house goes: bath, pajamas, teeth, two books, song, lights out. Every night. In that order. By the time Zuri was three she could recite it, and mostly she did not fight it, because there was nothing to fight. It was simply what happened after dinner. This is a routine: a fixed order of events that happens the same way every time. Routines work because young children cannot tell time and cannot plan, so an unpredictable day feels like a series of ambushes. A predictable day lets the child know what is coming and get ready for it.

Build routines around the hard parts of the day: waking up, leaving the house, meals, naps, cleanup and bedtime. Keep the order the same even when the times shift. Use transitions, warnings that a change is coming: "two more turns on the slide, then shoes." Toddlers and preschoolers hate being interrupted mid-thought as much as adults do; a warning lets them finish. A picture chart of the bedtime steps on the wall lets a preschooler run the routine herself, which she will proudly do. School-age children can help write the routine, and children who help write a rule follow it far more often.

Inside a routine, give choices. The rule is two options, both of which the adult can live with. "Red cup or blue cup?" "Walk to the car or hop to the car?" "Bath before books or after?" What the choice does is hand the child a small piece of real power at the exact moment she was about to grab for it by saying no. What it must not be is fake. "Do you want to go to bed now?" is not a choice, because the honest answer is no and the adult will not accept it. And "Which do you want, the couch, the chair, the floor, the rug, or my lap?" is too many; a three-year-old freezes.

The principle: most conflict with young children is about control, and a routine plus a choice gives the child control over the things that do not matter so the adult can keep control over the things that do. When Zuri asks for a third book, the answer is no, calmly, the same way every night. Because everything else about bedtime is hers, the no is easy to take.

A fourteen-month-old is pulling books off the shelf and chewing on the covers. Saying "no" gets a look and then more chewing, because to a fourteen-month-old "no" is a sound, not a plan. Redirection is the tool: take the book gently, hand him a teething ring or a board book that is his to chew, and move him three feet away. "Books are for reading. This one is for chewing." Redirection works for infants and toddlers because it replaces the forbidden thing with an allowed one instead of leaving a hole where the fun was. It works best when the replacement is close by and at least as interesting.

For preschoolers and older, add natural consequences: what happens by itself when a child makes a choice, with no adult adding anything. She refuses her coat; she is cold on the walk. He leaves his truck in the driveway; it gets run over. She does not eat dinner; she is hungry before bed and gets the same dinner back, not dessert. The adult’s job is to let it happen and skip the lecture. "You’re cold. Here’s your coat," teaches more than five minutes of "I told you so." Natural consequences are not for danger. A child does not learn about the street by being hit by a car; the adult holds the hand.

When there is no safe natural consequence, use a logical consequence: something the adult sets up that is related to the behavior, respectful, and reasonable in size. Crayon on the wall means you help wash the wall. Throwing sand means you leave the sandbox for the rest of the visit. Riding the bike into the street means the bike is put away until tomorrow. The link is what makes it teaching instead of punishment. Losing screen time for a week because of crayon on the wall is unrelated and too big; a four-year-old cannot connect them, so she learns only that the adult is unpredictable.

Two more tools. Ignore what is only annoying: whining, a tantrum in a safe place, a rude word said for effect. Attention feeds behavior, and behavior that gets nothing tends to fade. And catch the child being good, specifically: "You put the cups on the table without being asked." Children repeat what gets noticed. An adult who notices five good things for every limit she sets will find she has to set far fewer limits.

It is 7:30 p.m. Kofi has finished his bottle and his eyes are closing. Dani carries him to the crib. What she sees should be this: a firm mattress that does not sink under his weight, a fitted sheet pulled tight, and nothing else. No blanket, no pillow, no stuffed animal, no bumper pads around the rails. She lays him down on his back, not his side, not his stomach, zipped into a wearable blanket called a sleep sack, and she leaves. That is safe sleep, and it is the same every nap and every night until he is one year old.

The reason is SIDS, sudden infant death syndrome, and suffocation. In the early 1990s, doctors found that babies put to sleep on their stomachs died in their sleep far more often than babies on their backs. The "Back to Sleep" campaign that followed cut those deaths roughly in half. Soft bedding is the other killer: a baby who rolls face-first into a pillow or a blanket cannot lift her head away. The crib looks bare to an adult. To a baby it is the safest place in the house.

The rest of the rules, from the American Academy of Pediatrics: room-share, not bed-share. The crib or bassinet goes in the parents’ room for at least the first six months, but the baby never sleeps in an adult bed, on a couch or in an armchair with an adult; a sleeping adult can roll onto or against a baby. Keep the room a comfortable temperature and do not overdress; a baby who is sweating is too hot. No smoking in the home. Offer a pacifier at sleep time once breastfeeding is settled. Car seats, swings and bouncers are for travel and play, not for sleep; move a baby who falls asleep in one to a flat surface.

A baby who can roll over on his own may end up on his stomach, and that is all right; you still put him down on his back. Grandparents and older relatives often learned different rules, stomach sleeping, a blanket, a bumper to keep arms from getting stuck. The rules changed because babies died. The babysitter’s job is to follow the current rule every time, and a parent’s job is to tell every caregiver the rule and check that they follow it.

Get down on your hands and knees in the kitchen and look around. That is the view of a crawling baby, and from here the house is a different place: outlet slots at eye level, a dangling cord that leads to a hot iron, a cabinet with the dishwasher pods that look like candy, a trash can full of chicken skin, a pot handle sticking out over the edge of the stove. Childproofing is fixing the house from this view, before the child gets there, because no adult can watch a toddler every second and the house has to do part of the job.

Kitchen: cabinet latches on anything with cleaners, sharp tools or breakables; pot handles turned inward on the stove; the back burners first; no tablecloths a toddler can pull; hot drinks nowhere near the edge of a table. Bathroom: the water heater set at 120 °F or lower, because water at 140 °F can cause a serious burn in seconds; a toilet lock, since a toddler can drown in a few inches of water; medicines and vitamins in a locked cabinet up high, never in a purse on the floor. Never leave a child under about 5 alone in a bath, even for a moment, even to answer the door.

Everywhere: plastic covers or sliding plates on every outlet; cords for blinds cut short or cordless blinds, because looped cords strangle; furniture and televisions anchored to the wall, because a climbing toddler can pull a dresser over onto herself; gates at the top and bottom of stairs, with the top one screwed into the wall, not pressure-mounted; window guards or stops on upper-floor windows, since a screen does not hold a child; button batteries and magnets locked away, because swallowed ones burn through the gut. Small objects, coins, beads, balloons, anything that fits through a toilet-paper tube, out of reach of anyone under 3.

Poison: put Poison Control, 1-800-222-1222, in your phone and on the fridge. If a child swallows something, call before doing anything else, with the container in your hand; do not make the child vomit unless they tell you to. Keep a working smoke alarm on every level and a carbon monoxide alarm near sleeping areas, and test them monthly. Then, after all of this, still watch. Childproofing buys the seconds between when a toddler starts something and when an adult gets there. It does not replace the adult.

A car crash is the leading way children in the United States die from injury, and most of those deaths involve a child who was unrestrained or in the wrong seat. The right seat depends on the child’s size and stage, not just age, and the stages go in a fixed order. Every stage has one job: to keep the child’s body from moving forward into the crash, and to spread the force across the strongest parts of the body, the back, shoulders and hips, instead of the neck and belly.

Stage one is rear-facing. Infants and toddlers ride facing the back of the car, in an infant seat or a convertible seat, for as long as the seat allows, until they reach its top height or weight limit. Most children can stay rear-facing well past age 2. The reason is the neck: a young child’s head is heavy and the neck is weak, and in a frontal crash a rear-facing seat cradles the head, neck and spine together. Legs bent against the seat back are fine. Stage two is forward-facing with a five-point harness, again until the child outgrows the seat’s limits; the top tether strap must be attached to the anchor in the car so the seat cannot pitch forward.

Stage three is the booster seat, which lifts the child so the adult lap-and-shoulder belt fits: the lap belt low across the thighs, not the belly, and the shoulder belt across the middle of the shoulder and chest, not the neck or under the arm. A child stays in a booster until the belt fits without it, which for most children is somewhere around 4 feet 9 inches tall and between about 8 and 12 years old. Stage four is the seat belt alone, in the back seat until at least age 13, because the front airbag is built for an adult body.

Installation is where most seats fail. A correctly installed seat moves less than an inch side to side or front to back at the belt path. The harness is snug enough that you cannot pinch a fold of strap at the collarbone, with the chest clip at armpit level. No puffy coats under the harness, because they compress in a crash and leave the straps loose; put the coat on backward over the buckled harness instead. Seats expire, usually six to ten years after manufacture, and any seat that has been in a crash is replaced. Many fire departments and hospitals have certified technicians who will check an installation for free.

A grape is the perfect size and shape to plug a toddler’s airway. So is a hot dog, cut into rounds, and a cherry tomato, and a hard candy, and a chunk of raw carrot, and a marshmallow, and a spoonful of peanut butter, and popcorn. Children under about 4 have small airways and are still learning to chew and swallow in the right order, which is why food is the most common thing children choke on. The fix is mechanical: cut grapes and cherry tomatoes in quarters lengthwise, hot dogs in long thin strips, cook carrots soft, and skip nuts, hard candy, popcorn and whole marshmallows for anyone under 4.

Objects: anything that fits through a toilet-paper tube is a choking hazard for a child under 3. Coins, buttons, marbles, beads, small toy parts, the eyes on a stuffed animal, the cap of a pen. Latex balloons, whole or in pieces, are the leading non-food cause of choking death in children; a torn balloon molds to the throat. Check the age label on toys, keep an older sibling’s small toys in a separate bin up high, and get down on the floor and look. Meals happen sitting down, at the table, with an adult watching: no eating while walking, running, laughing hard or riding in the car.

Know the difference between a child who is coughing and a child who is choking. A child who is coughing, crying or talking is moving air; stay close, stay calm and let the cough do its work. A child who cannot cough, cannot cry, cannot speak, is turning blue or is making a high-pitched sound with a look of panic has a blocked airway, and the seconds count. For a child over 1 who is conscious: five sharp back blows between the shoulder blades with the heel of the hand, then five abdominal thrusts, fist just above the navel, pulling in and up, and repeat until the object comes out or the child goes limp. For an infant under 1: lay her face down along your forearm, head lower than body, five back blows, turn her over, five chest thrusts with two fingers on the breastbone, repeat.

Call 911, or have someone else call, as soon as you know the airway is blocked. If the child goes limp, begin CPR, and never sweep a finger blindly into the mouth; you can push the object deeper. This lesson describes the steps. It does not replace a class. A Red Cross or American Heart Association course in infant and child CPR takes an afternoon, includes practice on a manikin, and is the single most useful thing a babysitter or new parent can do before the first night alone with a child.

The parents have their coats on and the car is running. This is the moment to slow down, because everything you do not ask now you will have to guess later. A good sitter arrives ten to fifteen minutes early with a list, and a good family has the list already on the fridge. Either way the first section is emergency information: both parents’ cell numbers, where they will be, a second adult to call if the parents cannot be reached, the pediatrician’s number, Poison Control, and the house address with the nearest cross street, written down, because in a real emergency your mind goes blank.

The second section is the children. Names and ages. Allergies, with the exact reaction and the exact treatment: where the epinephrine auto-injector is and a demonstration of how to use it, where the inhaler is, what foods are off limits. The nine major food allergens the law requires on every label are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans and sesame; if a child is allergic to one, you read every label before serving anything. Medications: what, how much, when, and never anything not on the list. Medical conditions. Fears, comfort objects, the word the toddler uses for the bathroom.

The third section is the plan. What and when they eat. Bedtime, in steps, including what happens when the four-year-old asks for the third book. Where each child sleeps and the safe-sleep rules for the baby. What is allowed: which shows, how much screen time, whether they may go outside, which rooms are off limits. House rules for you: whether you may have a friend over (the usual answer is no), whether you may use the stove, what to do if someone comes to the door (do not open it), and how to lock up. Ask where the flashlight, the first-aid kit and the fire extinguisher are.

Then do a walk-through while the parents are still there. Look at the crib. Look at the stove, the door locks, the stairs. Ask what you are unsure about now; a question at 6:00 p.m. is free and the same question at 9:30 p.m. is a phone call to a parent at dinner. Finally, agree on when they will be home and how you will get home. When they return, report: what the children ate, when they slept, anything unusual, in order. Parents trust the sitter who tells them about the small cough more than the one who says "everything was fine."

A sitter who arrives with only a phone has a long evening ahead. A sitter who arrives with a plan for the age has an easy one. The plan does not have to be elaborate. It has to fit the stage, be safe for the space, and be something the sitter is genuinely willing to do on the floor. The first rule of every activity is active supervision: the sitter is in the room, watching and within reach, not in the next room checking messages. Most childhood injuries happen in the minute an adult looked away.

Infants, birth to 1: talk, sing, make faces, hold them where they can see you, shake a rattle, read a board book, lie on the floor for tummy time while they are awake and watched. Keep it slow; an overstimulated baby cries. Toddlers, 1 to 3: stacking cups, big blocks, push toys, a cardboard box, fat crayons on big paper, a bin of water on a towel with cups to pour (never unwatched), a song with hand motions, a walk to look at trucks. Expect short attention, about five minutes per activity, and expect to repeat the same thing many times.

Preschoolers, 3 to 5: pretend play with you in a role, a couch-cushion fort, play dough, simple board games with turns, drawing together, a scavenger hunt for five things that are blue, reading the same book with voices, helping make a snack. They love jobs: setting the table, sorting socks. School-age, 6 and up: card games, real board games, building projects, cooking something simple together if the parents allow the stove, a walk or ball game outside if allowed, and honestly just talking. Older kids often test a sitter with "my mom lets me." The answer is friendly and fixed: "I’ll check with her next time. Tonight the rule is what she told me."

Screens are a tool, not a plan. If the parents allow a show, use it for the twenty minutes you need to put the baby down, then turn it off. Have a quiet wind-down before bed: lights lower, voices lower, a bath if planned, books. Keep the space picked up as you go so the house the parents come home to is the house they left. And if a child is upset for you in a way you cannot fix, or sick, or something feels wrong, call the parents. That is not failure. That is the job.

This lesson is hard, and it belongs here, because the people most likely to notice that a child is being hurt are the people who see the child every day: teachers, child care workers, coaches, babysitters, neighbors, the older cousin. Child abuse is harm done to a child by an adult or older child: physical abuse, sexual abuse, emotional abuse, and neglect, the failure to provide food, shelter, clothing, medical care or supervision a child needs. Neglect is the most common form. Most abuse is done by someone the child knows and trusts, not a stranger.

Signs are patterns, not single events. Every child gets bruises on shins and knees; bruises on the back, the belly, the face, the ears, or in the shape of a hand or an object, or on a baby who cannot yet move on her own, are different. Burns in a pattern, like a cigarette or a hot object. Injuries the child explains in a way that does not fit, or that change with each telling. A child who flinches when an adult moves quickly, who is afraid to go home, who is hungry all the time, who comes to school in the same dirty clothes in winter, who is left alone at an age when he cannot be. Sexual knowledge or behavior far beyond the child’s age. A sudden change: a cheerful child who goes silent, a child who starts wetting the bed again, a teenager who stops eating.

If a child tells you something, stay calm, listen, and believe her. Do not interrogate; do not promise to keep it secret; do not react with horror, because she will stop talking. Say: "Thank you for telling me. This is not your fault. I’m going to get help." Then write down exactly what she said, in her words, with the date. In Illinois, teachers, child care workers, medical staff, coaches and many others are mandated reporters: the law requires them to report a reasonable suspicion of abuse or neglect. Anyone can report. The Illinois DCFS child abuse hotline is 1-800-25-ABUSE (1-800-252-2873), and a child in immediate danger is a 911 call.

You do not need proof. You do not investigate. You report what you saw and heard, and trained people decide what comes next. Reporting in good faith is protected by law; not reporting, for a mandated reporter, is not. The fear that stops most people, what if I am wrong, has an answer: if you are wrong, a caseworker makes a visit and nothing happens. If you are right and you said nothing, a child stays where she is. This chapter began with a list on a refrigerator. A child’s safety is a longer list, and the last line on it is: when you see something, say something to the people whose job it is to help.
