Thanks . . . I'll give it a try.
As I hit send, one other thing occured to me. Natural consequences. Tell the one going over to the other's house that if they fight, they will leave and tell the one who's house is having the gathering the same thing. And mean it. They start fighting------- get together is over. The whole family knows the situation-------- and it is to help them understand that they can not treat each other that way. A couple of times having to leave 5 minutes into a gathering should help them learn that they can't fight or be mean to each other. Good luck
Hey, I've got two boys that are brothers and have to live under the same roof that can be like this. Not so much the "mean" part but the fighting part/love hate part. We tell our boys that if they fight----------- they are seperated. They hate that and we follow through. I also think that the girls may need to have some verbal guidelines given ahead of time about what is expected and then tell them to work out those kinks for themselves.
Some kids will just fight. They both want their way, they both are inflexible with the other, etc. They either have to work it out or have less ture "play" time.
Good luck
