Most biting occurs in children between the ages of one-and-a-half and three years old. Its occurrence reflects not only the children’s feelings, but also their inability to use expressive language. Children usually bite when they’re afraid, angry, or frustrated, or in some cases, to have power over someone (i.e., to get/take something from another child). Additionally, a major change such a new baby or starting school may cause biting to surface. Children may also bite when they become over-stimulated or excited.
