My daughter is a hitter, not me but her big brother. When she hits him she gets a time out, and after that I make her kiss him and tell him she is sorry and I don't let her play with him the rest of the night. She adores her brother, and for the most part I think it is wrestling getting out of control, but he has had black and blue marks from her throwing stuff at him. I told her that if she is goin gto be mean, he won't play with her, then I have him shut her out of his room.
