GROWTH AND DEVELOPMENT :: Preschool (4 to 5 Years)


Children who bite others cause a great deal of concern for the parents. The parents of the child who has been bitten are also usually very concerned about infection. Biting is an unacceptable behavior that needs to be stopped at an early age to prevent further occurrences.

Why young children bite:

Although biting is fairly common in young children, it is often worrisome to adults. A family member, playmate, or classmate at daycare or preschool may be the one bitten. Biting can be painful and frightening when it occurs. It upsets other children and often angers teachers and other adults.

Biting is usually caused by one of four different factors, including the following:

  • experimental biting
    Experimental biting is done by infants and toddlers as they explore their world. They put everything in their mouths and sometimes bite in the process. You can help decrease biting by telling them, "No - biting hurts!" and being firm. Offer them things that they can safely bite on such as teething rings.
  • frustration biting
    Frustration biting happens when young children become frustrated and unable to cope with a situation. Until they learn how to play cooperatively, they may respond to the demands of other children by hitting or biting. Some helpful guidelines for decreasing this type of biting include:
    • Keep playtimes short and groups small.
    • Supervise young children's play closely.
    • If biting occurs, say, "No, don't bite. Biting hurts." and remove your child from the situation right away. Stay with your child and help him/her to calm down. Explore other, better ways to handle the situation with your child, so he/she learns to handle emotions differently next time.
  • powerless biting
    Powerless biting occurs when a child is in need of feeling powerful. Sometimes, the youngest child in the family uses biting to gain power. To help prevent this type of biting:
    • Make sure your child feels protected and is not always being "picked on" by others.
    • Explain the situation to bigger or older children and get their help to make things more equal.
    • If biting occurs, tell your child that he/she is not to bite and remove him/her from the situation right away. Stay with your child and help him/her to calm down. Explore other, better ways to handle the situation with your child, so he/she learns to handle emotions differently next time.
  • stressful biting
    Stressful biting is done when a child is under a lot of emotional stress. Biting may be a sign of distress or pain when the child is upset or angry. If this occurs:
    • Try to find out what is bothering your child. Watch for what happens right before the biting occurs.
    • Help your child to find other ways to express his/her feelings. Let him/her know that biting is wrong and remove him/her from the situation right away.

If your child bites, respond firmly, but calmly, to the biting. Let your child know that you disapprove and remove him/her from the situation. Help your child learn new ways to handle things. If your child bites repeatedly, be sure to consult your child's physician or healthcare provider about the problem.

What do I do if my child is biting others?

While every child is different, the following are some recommendations that may be used to help with the child who bites:

  • Be firm. Tell your child that you will not accept biting and why. Tell him/her biting hurts others.
  • Offer another behavior the child may use instead of biting. If the child bites because he/she is angry, have the child come to you and tell you this instead. A child who is younger than 18 months may need a toy that is allowed to be chewed on.
  • If you catch your child biting, use a firm "no" to stop the behavior, or try to stop the child before the biting actually occurs.
  • Use time-out if your child bites, or take away a favorite toy or activity.
  • Do not bite your child for biting someone else. This teaches your child that biting is still acceptable. Do not bite your child in a playful manner, as this might teach him/her to bite others.
  • Give praise when your child does not bite.
