Playing Too Rough
Why you shouldn't ignore it: You know that you have to step in when your child punches a playmate, but you shouldn't disregard more subtle aggressive acts, like shoving his brother or pinching a friend. "If you don't intervene, rough behavior can become an entrenched habit by age 8. Plus, it sends a message that hurting people is acceptable," says Parents adviser Michele Borba, Ed.D., author of Don't Give Me That Attitude!: 24 Rude, Selfish, Insensitive Things Kids Do and How to Stop Them.
How to stop it: Confront aggressive behavior on the spot. Pull your child aside and tell him, "That hurt Janey. How would it feel if she did that to you?" Let him know that any action that hurts another person is not allowed. Before his next playdate, remind him that he shouldn't play rough, and help him practice what he can say if he gets angry or wants a turn. If he does it again, end the playdate.
