This is probably a pretty ovious question but im gonna ask anyways. Little bit of info....we live on the same property as my parents, the previous owners converted a garage structure in the back into a little cottage. so my mom/dad/bro/sis are around all the time, many times a day. now my bro is bi polar and my sis has alot of issues, shes very mildly mr..16 but probably about 10 maybe 12 in maturity Know what I mean?? she has anxiety issues and she is very very odd. now..my difficult child LOVES his aunt and uncle to pieces and wants them around all the time. the problem is that when they, especially my sister are around he is much harder to handle, acts out more, is more aggresive, has more tantrums, because, i think anyways, he is feeding off of some of her issues and sees the way she doesnt act right and gets away with stuff, has fits (yes at 16) like you wouldnt believe! we are trying to include her in some of his therapy, trying to teach her what techniques we want to use and different ways to handle him. but its very hard, im really not sure its all sinking in Know what I mean?? the past 2 days she wasnt around much and i saw a bit of a difference in him. now seperating them, or not allowing her down here is not an option. i have a chronic illness and they are my help when my hubby is at work. so difficult child's therapist is helping some, or trying anyways lol my sister also has a tss aide who is trying to help. so my rock and a hard place is this....i KNOW she has her own issues, i understand, but now my difficult child has HIS own issues also so what can i do to make this work better? telling her the same thing 1000 times is not working lol i try to catch her when i see her winding up.....just need a few ideas, if anyone has any, to help me make this work better.
