Hitting, biting & hurting others (young kids)

A toddler who hits or bites isn’t a bad kid, and you aren’t a bad parent. They’re using their body because the words and brakes haven’t grown in yet.

By the numbers

How common it is, and what research says about responses.

Young kids

Age 2Hitting, kicking and biting usually peak around age two, when feelings are big and words are few.
Up to 1 in 2toddlers have been bitten at daycare, according to research cited by ZERO TO THREE.
1–5 yearsPediatricians say the toddler and preschool years are when a stable home, firm loving discipline and close supervision matter most for preventing aggression.

Discipline research

160,000+children were included in a review of five decades of research on spanking (2016).
13 of 17outcomes were linked with spanking, all harmful, including more aggression and defiance.
< 18 monthsPediatricians warn that physical punishment carries a higher risk of injury for babies under 18 months.

Why young kids hit and bite

Big feelings, few words and a brain still building its brakes.

Aggression is a normal part of early development. Young children have very little self-control, so when they are angry or frustrated they may lash out by hitting, kicking or biting.

Toddlers talk mostly through gestures and actions. A push or a bite can mean “I’m mad,” “Give me space,” “I’m overwhelmed,” or “I want that.”

👶 Babies (0–12 months)Grabbing, swatting and mouthing are exploring, not hurting on purpose.
Read more

Babies explore with their senses: mouthing, grabbing, shaking, dropping and swatting. They don’t mean to hurt anyone. A baby who is frustrated may kick and wave their arms because their body is their only way to show it.

Calmly move their hand away, say “Gentle,” and show them a soft touch.
🧸 Toddlers (12–24 months)Strong feelings, very little language, and early empathy.
Read more

This is when hitting, kicking and biting usually peak. Toddlers have strong feelings but limited words, self-control and understanding of how others feel.

Children don’t understand family rules until someone teaches them, and until about age 3 they don’t really understand punishment. Calm, clear limits work better.

🚸 Two- and three-year-oldsThey may know the rule, but feelings win in the moment.
Read more

Between 24 and 36 months, emotions often outweigh thinking skills. A child can know “no hitting” and still hit when upset. Toddlers are also starting to see themselves as separate people and want independence.

🌋 Big reactorsSome children are simply more intense.
Read more

Children who are intense “big reactors” tend to have a harder time managing emotions than easygoing children, and rely more on actions to show strong feelings.

Temperament isn’t anyone’s fault. Intense kids often feel joy and love intensely too.
🦷 Why biting in particularTeething, curiosity and needing something to chew.
Read more
  • Curiosity about cause and effect: “What happens if I bite?”
  • Needing more active play to burn off energy
  • Not having words for excitement, anger, tiredness or frustration
  • Teething, or a need for something to chew on
🥱 Tired, hungry or out of routineLow reserves mean shorter fuses.
Read more

Tiredness and hunger often set off outbursts. Timely naps and meals prevent many of them. Transitions and being interrupted are common triggers too.

Changes like a new baby, a move, a new room at child care or the loss of a pet can make a child feel less secure.

Finding the pattern

Where, when, who and what came right before.

Patterns in when and where hitting or biting happens can tell you what your child is trying to say, and how to get ahead of it.

Questions to ask yourself

  • Has anything changed lately at home or child care?
  • What happened right before? A toy taken? Being told it’s time to leave?
  • When does it happen? Before naps, at transitions, when interrupted?
  • Where does it happen? Somewhere crowded, loud or busy?
  • Who is it aimed at? One child, a few, or anyone nearby?
Use the “What happened before?” worksheet in this guide for a week or two. Many parents spot a pattern quickly.

Stopping it calmly in the moment

Calm, quick, short words, and safety first.

Staying calm is the essential first step. Your calm helps your child settle faster, and children need help calming down before they can learn anything new.

When your child hits or bites

  1. Step in right away. Take a breath so your voice stays calm and firm, not angry.
  2. Stop the behaviour. Use a “stop” gesture, gently hold their hand if needed, or move them away.
  3. Name the feeling and the limit in a few words: “You’re really angry. Hitting hurts. I won’t let you hit.”
  4. Turn to the child who got hurt and comfort them.
  5. Help your child calm down: a quiet corner, a hug, or something new to focus on.
  6. Later, when calm, show them what they could do instead.
🤫 Fewer words, more calmLong lectures don’t land with a toddler who’s upset.
Read more

Pair a few calm, firm words with a gesture. Expect to repeat this many times before words alone work.

Pediatricians suggest skipping threats. Briefly ignore small misbehaviour, and teach the behaviour you want instead.

🛋️ A cozy calm-down cornerA break, not a punishment.
Read more

Set up a calm, safe space with pillows, books and soft toys, and let your child help make it. Present it as a place to feel better, and notice when they settle.

Short time-outs are okay for preschoolers, but pediatricians suggest using them sparingly. A common rule of thumb is about one minute per year of age.

🎈 Distract and redirectSometimes the fastest calm is something unexpected.
Read more

For a very upset child, try something surprising, like inviting them into a game or offering a big hug. Redirecting to another activity can help, without bribing.

Try saying: “You’re upset the TV went off. Look how high this ball bounces!”
⏰ Head it off before it startsWarnings and small choices make transitions easier.
Read more

Give advance notice before changes and offer a limited choice. If your child tends to bite when someone gets close or takes a toy, step in early and help them protect their space.

Try saying: “Two more pages, then we head to the car. Which book should we finish with?”

Caring for the child who got hurt

Comfort first, and when a bite needs a doctor.

Separate the children and comfort the one who was hurt. Keep them apart until everyone has calmed down.

🧼 Caring for a biteMost toddler bites don’t break the skin. If one does, clean it well.
Read more

Wash the bite with soap and water for 5 minutes, then rinse under running water for a few minutes. Press with a clean cloth if it bleeds, and a cold pack can ease swelling.

Call your child’s doctor if…

  • A human bite breaks the skin
  • It’s a puncture on the hand or face
  • You see redness, red streaks, pus, or fever
  • Your child looks or acts very sick
If bleeding won’t stop after 10 minutes of pressure, go to the emergency room. If you think it’s life-threatening, call 911.
🫂 If your child was the one bittenIt’s upsetting. Your child’s feelings, and yours, matter.
Read more

Being bitten is common at daycare and is part of toddler development, but it’s still a safety concern. Ask the provider what happened and what they are doing about it.

Comfort your child and let them talk or play about it. Avoid labelling the other child, who is learning too.

Teaching gentle hands and words

Give their body and feelings somewhere better to go.

A parent’s long-term job is teaching children to name feelings and show them without hurting anyone. It takes time and patience, and children usually keep biting until they’ve learned something to do instead.

💬 Words for big feelingsTeach “I’m mad!” before they need it.
Read more

Teach children to express feelings with words instead of kicking, hitting or biting. Name feelings often in calm moments, and practise using them.

Simple words to practise

  • “Back up, please.”
  • “I’m mad!”
  • “Help, please.”
  • “My turn next.”
  • “Stop. I don’t like that.”
🦶 Safe ways to let it outStomp, jump, squeeze, tear paper.
Read more

Offer acceptable outlets for big energy: stomping, jumping, pushing into couch cushions, tearing paper or drawing an angry picture. Practise these when your child is calm so they’re ready when needed.

For biting, a teething toy or something safe to chew can help a child who needs to bite.

🔀 Other ways to solve the problemSaying no, walking away, getting help.
Read more

Show your child how to say no firmly, turn away, or find a compromise. Teach them to tell a friend to back up, and to get an adult if the friend doesn’t stop.

Timers, or having more than one of the most popular toy, can make sharing easier.

🌟 Catch them being gentlePraise the stomp instead of the hit.
Read more

Give praise and affection when your child is kind and gentle. Be specific, and praise self-control, like stomping instead of hitting.

Try saying: “You were so mad, and you stomped your feet instead of hitting. That was hard, and you did it.”
📚 Books, play and practiceTeach in calm moments, not in the heat of it.
Read more

In calm times, use age-right books or videos about biting and gentle hands. Pretend play, with dolls or stuffed animals acting out what to do when they feel mad, is another way to practise.

Avoid calling your child “a biter” or “a hitter.” Labels can make the behaviour stronger and become part of how a child sees themselves.

Why hitting back or harsh words backfire

Biting a biter or smacking a hitter teaches the opposite.

The American Academy of Pediatrics advises that parents should not spank or hit children. Spanking often increases aggression and anger rather than teaching self-control, and can lead to a cycle of more misbehaviour and more spanking.

Yelling and shaming are also ineffective and harmful, even from loving parents. Children often copy how their parents handle anger, so showing calm is one of the best teachers.

❌ Myth: Biting back shows them how it feelsFact: It teaches that hurting is how grown-ups solve problems.
Read more

Pediatricians recommend modelling nonviolence, and teaching toddlers not to hit or bite by not spanking. Children learn far more from what we do than what we say.

❌ Myth: A smack works fastFact: Research finds no link to better behaviour, now or later.
Read more

A review of five decades of research found spanking was not linked to children doing what they were asked, either right away or later, and was linked to more aggression and defiance.

❌ Myth: Gentle means no limitsFact: Calm parenting still sets firm, clear limits.
Read more

Gentle parenting is not permissive parenting. It still uses clear limits. Consistent, predictable rules help children learn, while mixed responses can encourage the behaviour.

The “Discipline without yelling or hitting: what actually works” guide goes deeper on consequences, time-in and repair after you lose your cool.

Daycare, preschool and school

Working with teachers as a team.

Daycares often take action when biting keeps happening, because it’s a safety concern. Your child’s provider should be your partner in working out what’s behind it.

Questions to ask the provider

  • Is it the same child each time, or different children?
  • What happened right before?
  • What was my child doing, and where?
  • Who was my child playing with? Is that a usual friend?
  • Who was supervising, and how did they respond?
🔗 Use the same plan everywhereSame words and steps at home and at child care.
Read more

Ask the provider to use the same strategies you use at home. If your child has been sent home, plan a gradual return together.

Stay in close touch with teachers and caregivers so you can follow how things are going.

💭 When it feels personalA note home about biting can sting. It isn’t a verdict on you.
Read more

Aggressive behaviour is a typical part of early childhood, and biting does not mean a parent has failed. Looking for information is a sign of good parenting.

Playdates, parks and family gatherings

Stay close, plan ahead, and end early if needed.

Watch for conflict with playmates. Let small disputes sort themselves out, but step in if a physical fight keeps going after you’ve asked them to stop. For a very violent fight, end the playdate.

Ideas that help

  • Bring a comfort item, and let relatives approach slowly
  • Look at photos of who you’ll see, or practise with pretend play beforehand
  • Make clear that who “started it” doesn’t matter: hurting is never okay
  • Plan visits around naps and snacks
  • Stay within arm’s reach of a child who has been hitting or biting
If hitting is mostly between brothers and sisters, the “When siblings hit, fight & compete” guide has more.

When you feel embarrassed, angry or worn out

Your reactions matter, and so do you.

It can be hard not to feel judged when your child hurts someone. Try to notice how you handle your own feelings, whether your reactions are helping, and what your child might be learning from them.

💪 No need to apologise for limitsCalm, confident discipline helps a child feel safe.
Read more

Pediatricians suggest not feeling guilty or apologising when you set a limit. If a child senses mixed feelings, they may decide they were right and the parent is the “bad” one.

👫 Both parents, one planSame words, same steps, whoever is there.
Read more

Being consistent helps children learn. Responding one way one day and another way the next can encourage the behaviour.

Agree together on your words and steps, and share them with grandparents, sitters and other carers.

🌬️ Take a breath, or a breakYou can’t calm a child when you’re boiling over.
Read more

Breathe deeply, and take a short break yourself if you need to. If you express anger in quiet, calm ways, your child is likely to follow your example.

When and where to get help

Signs it’s more than a phase, and who can help.

Talk with your child’s doctor if…

  • Aggression keeps happening for more than a few weeks and you can’t manage it on your own
  • It causes injuries, like teeth marks, bruises or head injuries, to others or your child
  • Your child attacks you or other adults
  • Your child has been sent home from child care or kept from playing by neighbours
  • You fear for the safety of others around your child
  • It gets in the way of friendships, learning or everyday outings

Other signs to mention

  • Aggression that started after a frightening event or big life change
  • Aggression with no clear reason
  • Biting several times in one week
  • Hitting or pushing that seems to be about seeking strong physical sensation
  • Seeming fearless or reckless, or often breaking things

Your child’s doctor can check development, refer you to child development specialists or early intervention, and help plan reward-based strategies for home and child care. These work best when started early.
