I'm about at my wits end and wondered if anyone can give me some advice or words of wisdom.
As many of you know, by my "hostile foster parent" post, I have a 10 yr old girl (T) who has been doing weekend visits and will be moving in with us on 12/23 as a pre-adoptive placement.
T's sister, 12 yr old B, also visits with us on the weekends and her permancy plan is to also move in with us in a few months, after T has settled in, also as a pre-adoptive placement. She is currently in a group home and is doing excellent there.
The problem that has come up over the last couple of visits is the constant fighting between T and B. I am at my wits end and finally let them have it today and told them that if they wanted to live together they needed to get along because I can not spend the next ten years playing referee!

Also T has a way of insticating my 9 yr old son and gets him so hyped up that he winds up in trouble with me. When T and B are not here my son is the calmest sweetest child (well.... usually

). He becomes definant and won't listen to me or calm down! The other issue is also that B doesn't get along very well with my 10 yrs old as luck would have it T has taken a likeing to her and I'm sure this is causing jealousy.
Well, I have to go and break up another fight!! It sounds like a heard of screaming elephants upstairs and I am waiting for them to fall through the ceiling. I have to admit I've about had it and don't know how much more I can take. I just can't stand the constant fighting and screaming.
