Children and Biting
Biting adults or other children is a common behavior in most toddlers and increases when a child is tired or frustrated.
It is important to not overreact when it occurs, instead treatment consists of teaching your child that it is not acceptable behavior.
Some steps to take when your child bites include:
Immediately look him in the eye and give him a loud and firm 'NO.' You may also move him to another area for a time out. Let him know that it is never all right to bite another person because it hurts.
Supervise your child closely when he is with other children, so that you can distract him or interrupt any behavior that may lead to biting.
It is important to not overreact and never bite your child back. Biting him back or physical punishment will just reinforce that it is okay to hurt others.
Give him lots of praise when he controls himself and doesn't bite.
