There’s a time to get angry, and it’s best for your child if you do. Let’s say your child hits a playmate with a toy hard enough to make the other child cry. How can you teach your child to feel sorry so he or she won’t do it again? Researchers say the best way for parents to react（反应）is to show their anger and to let the child know exactly why they are mad.

　　Many parents believe that it is best to control their feelings and to wait until they’re calm before scolding their children. But the mother or father who explains reasonably to a child , “Peter was crying because you hit him,” is not likely to attract much attention. Young children need to be scolded immediately, and strongly, before they’ll take criticism （批评）to heart.

　　When your young child does something wrong, scold him or her seriously at once. At the same time be sure to tell the child clearly what he or she has done wrong. An angry reaction without an immediate explanation does little good. Forbidding a child to play outside or not allowing him to watch TV as a punishment works well-but only when taken together with an explanation. Make sure your child understands that although his or her wrongdoing has made you angry, you still love him or her. Use simple, direct words such as, “You hurt peter. How would you feel if he hit you? You must never, never hurt people.” If your voice expresses strong feeling clearly, your message will carry enough weight.
