Small children do not have the verbal skills to express their emotions. They may know what they want to say, or what they are feeling, but can t get the words out. Physical activities are much easier and a much more natural course, especially for a toddler. If another child takes his toy he may react by hitting or biting. If biting gets a strong response, the child will continue to bite to communicate their anger.
Children live in a sensory world.
They develop their sense of taste and feel early, and enjoy experimenting with them. Even the youngest children will put things in their mouths to explore the taste and feel of an object. When a child gets teeth, this can add a whole new dimension to the exploration. A child may bite, not out of anger, but out of curiosity. This problem sometimes occurs in the smallest of a family or group of children.
