Ok....big difficult child has been boiling the last 3 days....started last night with more than hour meltdown because we took away some games, because he becomes more and more verbally abusive, threads, exct. Tonight he played with a friend from down the street, but because this child is a bit mentally challenged, he irritates difficult child and usually ends up with verbal abuse, bossyness, exct from difficult child. Tonight was the first time he ever got physicly abusive, pushing this child, holding him against his will, because this boy said he wanted to go home! My hubby intervened, a bit aggressively, trying to free this child, so difficult child shouted infront of his friend to hubby f*c* you! This was so embarresing.....difficult child became very emotional, labile, shifting from angry to crying, to hating himself, to packing a suitcase, wanting other home.....depressed, exct! Then suddenly he is better again! I dont feel its ok for this other child to play here.....I feel he aggrivates my sons behaviour and Idont like the way my son abuses him! Do I speek to him and tell him not to come and play anymore, or what!? My son dont really have insight, his defence meganism is:" I dont care....." Maybe its time to take my son to this other therapist who specializes in Reactive Attachment Disorder (RAD)....We really dont know what to do anymore! But this cant be normal, just manipulative or naughtiness!
