The purpose of discipline is to teach your child how to behave, so that your child will have mostly "good" behavior - behavior that is kind and cooperative with others, and not very much "bad" behavior - behavior that is hurtful or uncooperative or "not the way she's suppose to act." The bad behavior, or misbehavior, is a normal part of childhood and a normal part of learning how to behave. Your child learns the difference between good and bad behaviors by the ways that you react to them - by the ways you discipline your child.
