They have trouble asking for things or requesting help. They haven't learned yet how to play with others. At times, when they can't find words to express their feelings, they resort to hitting, pushing, or biting. A child's world can be stressful, too. A lack of daily routine, interesting things to do, or adult interaction are stressful situations for children.
Children also experience stressful events like death, divorce, or a move to a new home.
Biting is one way to express feelings and relieve tension. If you determine that the biting occurs as the result of exploration or teething, you may want to provide the child with a cloth or teething ring to gnaw on. If a child seems to bite when tired or hungry, you may want to look at your daily routine to be sure that he is getting enough sleep and nourishment. If the biting occurs when two children are fighting over a toy telephone, you may want to purchase an extra toy telephone. It does not work to make very young children share.
