My daughter will be two and a half next month. She has entered a terrible hitting phase with other children and me and my husband. I don't know how it started, or how to stop it. My husband and I hardly ever spank, because she responds well to time-outs. That usually consists of 2 minutes in her room. Today she all-out pummeled the little girl next door while we were playing outside. I was so outraged and embarrassed. We came inside and I shut her in her room (she can't open doors yet) for over and hour. I explained to her that she was in big trouble and that she may as well lay down and take a nap because she wasn't coming out of her room for the rest of the afternoon. She cried, and screamed, and kicked the door, and then she quieted down and played, but I was debating how long I should have left her in there. Is grounding a 2 and a half year old pointless? I mean, she knows she was in trouble, but is it mean to leave her in her room for over an hour? I was just fed up and wanted her to get the point that we can't play with our friends if we hit them. Does anybody have a better solution for dealing with this? Or think it's mean that I grounded her?
