Why Might My 19–24-Month-Old Hit or Bite?

Read the UK edition

The short answer

Hitting and biting can happen while toddlers are still learning to communicate and control impulses. Stop the action calmly, care for anyone who is hurt, and show your child what to do instead. Seek support if the behavior is persistent, causes injury, or feels unsafe.

Keep in mind

  • Prioritize safety and use a brief, clear limit such as “I won’t let you bite.”
  • Teach and praise a safer way to ask for help, space, or a turn.
  • Look for patterns such as tiredness, frustration, crowding, or difficulty communicating.

Why might hitting and biting happen at this age?

Toddlers are still learning to express anger, frustration, excitement, and needs with words and actions.

Limited impulse control and communication can mean a child hits, bites, or pushes before they can explain what is wrong.

This behavior does not by itself mean that a child will grow up to be aggressive, but adults should respond consistently and keep others safe.

What should I do in the moment?

Move close and calmly block the hit or bite; separate children if needed to prevent further injury.

Use a short, clear phrase such as “I won’t let you bite” or “Hitting hurts.” Avoid a long explanation while your child is upset.

Check and comfort anyone who was hurt, then help your toddler move to a safe activity once everyone is calm.

Why avoid shouting or punishment?

Shouting, hitting back, or shaming can frighten a toddler and does not teach the skill you want them to use instead.

Children under 3 are still learning to control impulses; clear limits and repeated teaching are more useful than expecting them to understand punishment.

Stay as calm as you can and follow the same safety rule each time.

How can I show a safer alternative?

Give your child a simple word, gesture, or action to try, such as “help,” “stop,” handing you a toy, or asking for a turn.

Model gentle hands and show what to do when they feel frustrated, such as moving back or coming to you.

Notice and praise attempts to use the safer action, even if your child still needs help.

How should I respond to the person who was hit or bitten?

First check the person who was hurt and offer comfort or first aid as needed.

Use simple words to describe the effect: “That hurt. We are checking on them.”

Do not force an apology while your toddler is distressed; later, model a kind action such as bringing a cool cloth or giving space.

What can I look for to reduce repeat episodes?

Notice what happened just before the behavior: tiredness, hunger, excitement, frustration, crowding, or a toy conflict may be involved.

Stay close, step in early, and keep routines predictable; help your child communicate needs before frustration grows.

Give positive attention when your child uses gentle touch, waits, or asks for help.

How can I coordinate with childcare or other caregivers?

Tell other caregivers the same brief limit and safe alternative you use at home.

Ask what tends to happen before an episode and what helps your child settle.

Agree on how adults will protect the children involved, record repeated episodes, and communicate with each other.

When should I seek support?

Talk with your child’s clinician if the behavior continues for several weeks, causes bruises or other injuries, or happens frequently despite consistent support.

Seek advice if your child hurts adults, is excluded from play or childcare, or you feel unable to keep people safe.

Share examples from home and childcare; patterns across settings can help determine what support may help.

What can I do today?

Choose one short safety phrase, such as “I won’t let you hit,” and use it calmly.

Think about a safer word, gesture, or action to teach your child when they want help or space.

Notice when the behavior happens and what may have triggered it.

Praise gentle touch and ask other caregivers to use the same basic response.

When to seek support

Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.

  • Talk with your child’s clinician if hitting or biting is persistent, causes injuries, is directed at adults, or makes you concerned about anyone’s safety.
