But he and Carol were more concerned about Annie's behavior and what it meant. She was frightened. The child's coping strategies couldn't meet her needs.

All children bite at some point in their early years.
Biting usually begins accidentally during the teething phase. The baby uses her mouth to get what she needs - comfort for her sore gums. It's one of the ways babies explore their environment. Some infants also may bite when they are excited or while playing. Even though biting in an infant is not a concern, it is still a good idea to redirect the behavior early on.
