Toddler hitting and biting: why it happens and what to do

Hitting, biting and pushing are some of the most common, and most upsetting, things toddlers do. They're rarely about wanting to hurt anyone. The NHS page on tantrums and toddler behavior says most young children occasionally bite, hit or push another child, and that this doesn't mean your child will grow up to be aggressive. KidsHealth's guide to biting says biting happens most often between the first and second birthdays and should stop by about 3 or 4.

What works best is a calm, quick and predictable response: step in, keep everyone safe, use a few firm words, comfort the child who was hurt, and later teach what to do instead. Never hit or bite back. This guide covers why it happens, what to do in the moment, how to prevent it, biting at childcare, caring for a bite and when to get help. For meltdowns more broadly, see toddler tantrums.

Why do toddlers hit, bite and push?

Toddlers have strong feelings, a strong drive for independence and very little self-control. Zero to Three's guide to aggressive behavior in toddlers explains that toddlers rely on actions to communicate, so a hit can mean "I'm mad!" or "You're too close to me". It says aggression typically peaks around age 2, and that toddlers are only just beginning to develop empathy, so they can't yet see how the other child feels. The AAP's page on emotional development at 2 says toddlers who are stopped from overstepping a limit may hit, bite or kick, because they don't have much control over their emotional impulses.

Common reasons include:

• Limited language. Zero to Three's biting guide describes biting as a substitute for the messages a child can't yet put into words.
• Testing cause and effect. KidsHealth says some toddlers bite to see whether it gets a reaction, and Zero to Three notes that babies explore by grabbing, biting and swatting without meaning to hurt.
• Frustration, anger or fear, especially over toys and turn-taking.
• Feeling overwhelmed by noise, crowds or too much going on.
• Tiredness, teething or a need to chew. Zero to Three lists being over-tired, teething and needing oral stimulation. See teething.
• Big changes, such as a new baby or a move, which Zero to Three names as common triggers.
• Wanting attention. The NHS says children may behave this way when they need more attention.

What should I do the moment my toddler hits or bites?

1. Stay calm. Zero to Three calls this the essential first step. Take a breath before you speak; a big reaction can make your child more upset, or make biting more interesting.
2. Step in straight away. The AAP's tips on aggressive behavior say to step in when one child is hitting or biting another, and to separate the children until they calm down. Who started it doesn't matter. Zero to Three suggests gently but firmly holding your child's hand if needed.
3. Use a few firm words. "No biting. Biting hurts." or "No hitting. Hitting hurts." KidsHealth says to avoid long explanations, which toddlers can't take in mid-moment.
4. Comfort the hurt child first. Zero to Three suggests shifting your attention and sympathy to the child who was hurt, which also models empathy. Heavy attention on the child who bit, even cross attention, can reinforce it.
5. Name the feeling, then redirect. Zero to Three suggests something like "You're really angry. You want to stay at the playground, but it's not OK to hit Mom." KidsHealth suggests moving on to another activity, such as dancing or drawing, once things are calm.
6. Offer a calm-down space if needed. Zero to Three suggests a quiet, cosy spot with books and soft toys as a break, not a punishment.

If biting or hitting keeps happening, KidsHealth suggests a short time-out of about 1 minute per year of age, supervised but without attention. The AAP says time-outs should be used sparingly, as a last resort, and the CDC's tips for toddlers suggest only very brief time-outs at this age.

Why shouldn't I hit or bite back?

It can be tempting to "show them how it feels", but every major source says not to. The AAP's discipline guide says parents and carers should not spank or hit children, because it teaches that causing someone pain is OK if you're frustrated, and children who are smacked may be more likely to hit others. KidsHealth says never to hit or bite a child who has bitten, as this teaches that the behavior is acceptable. The NHS says hitting back could make your child think it's acceptable.

Australia's Sydney Children's Hospitals Network adds that smacking might stop a behavior in the moment but doesn't teach a child why it was wrong, and over time can make behavior worse. Your calm response is the lesson: big feelings are OK, hurting people isn't, and grown-ups stay in control.

If you feel close to losing your temper, put your child somewhere safe and step away for a minute. For support, contact your pediatrician's office.

How can I teach my toddler what to do instead?

Stopping the behavior is only half the job. Zero to Three says interrupting without giving an alternative makes the behavior more likely to continue, and the CDC says to always tell or show your child what to do instead.

• Give them words. KidsHealth suggests teaching "no", "stop" or "that's mine", and showing your child how to hold out a hand to ask for a toy. Zero to Three suggests phrases like "You're too close to me." See first words.
• Offer safe outlets. Zero to Three suggests jumping, stomping, hitting sofa cushions, ripping paper or painting an angry picture. The NHS suggests a big space like a park where your child can run and shout.
• Praise what you want to see. The AAP suggests praising good behavior regularly, not only reacting to misbehaviour. Be specific: "You stomped your feet instead of hitting. Great job."
• Plan around triggers. Zero to Three suggests warning before transitions, offering choices, protecting sleep and active play, and offering crunchy snacks at regular times. Have duplicates of favorite toys, or use a timer for turns.
• Offer something safe to chew. If your child bites when teething or seeking oral input, Zero to Three suggests a teether or crunchy food.
• Model calm. The AAP says children often copy how their parents handle anger.
• Don't label them. Zero to Three advises against calling a child "a biter", because labels can stick.

From around 2½ to 3, Zero to Three suggests a few more steps once your child is calm: point out what happened ("It hurt"), think of better choices together, and remind them they can always come to you for help.

What helps when biting happens at childcare?

Biting and pushing are common in group care, where toddlers share space and toys all day. The aim is for home and childcare to respond the same way.

• Talk to the educators early. Zero to Three suggests sharing what you know about your child's sleep, teething and sensory needs, so carers can watch closely and reduce triggers.
• Agree on the words. Use the same short phrase at home and at care, as Zero to Three suggests. KidsHealth suggests the same "no biting" rule everywhere.
• Look for patterns together. Zero to Three suggests noting what happened just before each bite, who was involved, where and when.
• Keep active play. Zero to Three advises against taking away outdoor play as a punishment, because it may make the problem worse.
• Stay in touch. The AAP suggests keeping in close contact with teachers and carers. KidsHealth says a calmer, smaller setting may help if biting keeps happening there.

If your child is the one who was bitten, it's reasonable to ask the center how they handle biting and how they'll let you know about any incidents. For settling in, see starting childcare.

How do I care for a bite that breaks the skin?

Many toddler bites only bruise. The AAP's bite advice says bites that don't break the skin can't become infected and can be cared for at home, with a cold pack for about 20 minutes for pain or bruising.

If the skin is broken:

1. Wash it. The AAP suggests washing with soap and water for 5 minutes, then rinsing under running water for a few minutes.
2. Let it bleed slightly. The NHS bites page suggests gently squeezing the wound so it bleeds a little, unless it's already bleeding.
3. Stop heavy bleeding. Press a clean cloth or dressing firmly on it. The AAP suggests 10 minutes of direct pressure.
4. Pat dry and cover with a clean dressing, as the NHS suggests.
5. Get it checked today. The AAP says a human bite that breaks the skin needs medical care now, and the NHS says to get urgent advice if a person bit you. The AAP notes human bites are more likely to get infected than animal bites, especially on the hands. A doctor may check your child's tetanus vaccinations and decide whether antibiotics are needed.

For pain relief, check the label or ask a pharmacist.

When should I get help?

Call 911 now if a bite is bleeding heavily and you can't stop it (AAP).

Go to the emergency room if bleeding hasn't stopped after 10 minutes of firm pressure, or the wound is large or deep (AAP, NHS).

Get medical help today (same-day doctor or your pediatrician's after-hours nurse line) if:

• a human bite has broken the skin, especially on the hand, face, head or feet (AAP, NHS)
• a bite becomes red, swollen, hot or smelly, leaks fluid or pus, or has red streaks; the AAP says infection can start from 8 hours to 3 days after a bite
• your child has a fever or seems unwell after a bite

Talk to your doctor or pediatrician if:

• biting continues past about 3 or 4, happens a lot, or is getting worse rather than better (KidsHealth)
• aggression has lasted more than a few weeks and you can't manage it, your child injures others or attacks adults, or they're being sent home or left out of play (AAP)
• it's getting in the way of relationships, play or learning, or happens several times a week over time (Zero to Three)
• your child seems fearless or reckless, hits for no clear reason, or became aggressive after a frightening event or big change (Zero to Three)
• you think your child's speech may be delayed; Zero to Three suggests a speech assessment, and milestones from 12 to 24 months shows what's typical

The NHS says that if you're seriously concerned about your child's behavior, talk to your doctor or pediatrician.

What's worth noting down?

For a week or two, jot down each hit or bite: the time, where it happened, who was involved, and what happened just before (a toy grab, a crowd, a late nap). Zero to Three suggests exactly this kind of pattern-spotting, and it often shows a trigger you can plan around. The same notes help your child's educators, and your doctor or pediatrician if you need advice.
