I was at my sister's house today when I witnessed my nephew trying to bite the nanny because the nanny wanted to take away a piece of diaper that he was playing with. That action brought him a light pinch on the face and scolding from my sister which immediately sent him wailing. I reprimanded my sister; Not for giving my nephew his due punishment but for not explaining to him why he was being punished. I found this article quite interesting and probably you, and even I, can make used of some of these information provided in the article.
Parents are often dismayed and outraged when a playmate at daycare or on the playground bites their child. If your child is the biter, feelings of despair, anger, and helplessness may lead to a series of ineffectual punishments and interventions. What can you do to discourage your little biter?
