The short answer
Toddlers may hit or bite when upset or in conflict because self-control and communication are still developing. First stop the harm and keep everyone safe. Use a short, calm limit, then teach a word or action your child can use instead. Repeated injury or unusually intense aggression needs professional advice.

Keep in mind
- Stop hitting or biting and attend to anyone hurt.
- Accept the feeling while keeping the limit on harmful behaviour.
- Model simple words, moving away, or asking an adult for help.
- Do not hit, bite, shame, or shout back.
Why can hitting or biting happen?
A toddler may not yet have the self-control or words to express frustration peacefully and may lash out physically.
The behaviour needs a clear limit, but it does not make your child bad. Their feeling can be real while hurting someone remains unacceptable.
What should you do first?
Block further harm gently, separate the children if needed, and check the injured person. Stay nearby while everyone settles.
Use a brief limit: “Hitting hurts. I will not let you hit.” If a human bite breaks the skin, seek NHS 111 advice; a large or deep wound or bleeding that will not stop needs A&E assessment.
Acknowledge feelings and keep the boundary
Your child may be angry, disappointed, or unwilling to give up a toy. Put the feeling into a short sentence: “You are angry.”
Follow with the limit: “You can feel angry, but I will not let you hurt someone.” Keep your response calm and clear.
Teach an alternative
Stopping the behaviour is only the first step; show your child what to do instead.
Model words such as “No,” “My turn,” or “Help,” and practise moving away, asking an adult, or choosing another toy.
Look at what happened beforehand
Notice patterns around waiting, toy conflicts, jealousy, noise, or changes in the setting.
Hunger and tiredness can make coping harder, but do not assume every incident has the same cause. Look at each situation.
Do not teach through hitting
Physical punishment, shouting, and humiliation do not provide a useful model for handling anger. Never bite or hit back.
A calm adult response, repeated limits, and redirection help show the behaviour you want your child to learn.
Notice safe behaviour
Give specific positive feedback when your child handles a difficult moment safely.
“You asked me for help” or “You used gentle hands” makes the behaviour you want to encourage easier to understand.
When is professional help needed?
Contact your GP or health visitor for injuries, attacks on adults, aggression that remains unusually intense for weeks, or fear about anyone’s safety.
Report any loss of language, social, or movement skills promptly too. Do not wait for several weeks if there is immediate risk or a concerning injury.
What can you try today?
For a week, briefly note what happened just before each incident, such as waiting, a toy conflict, or tiredness.
Choose one limit phrase and two alternatives. Ask carers to use a similar approach and supervise situations where harm has happened.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- A human bite breaks skin: seek NHS 111 advice. A large or deep wound or bleeding that will not stop needs A&E assessment.
- Aggression towards adults or fear for anyone’s safety needs prompt support.
- Unusually intense aggression persists for weeks or family coping is worsening.
- Loss of previously acquired skills needs prompt assessment.
