I have a grandson age 6 who has many behavior problems. He has these terrible fits that we can not control. He says horrible things to his 12 yr old brother. He says he hates him, he wants him to die, he wants to stab him in the heart. When he is sent to his room he screams at the top of his lungs. He has ALWAYS rocked himself in bed. Banging his head on the wall for hours. He will find knives and stab holes in my daughters couch, stab all his sisters diapers up (she's 9 and is disabled with Rett Syndrome).He has set fire to his bed and to his stuffed animals. He has destroyed his sisters therapy toys. He has run away from home, crossed a major 4 lane street. The police picked him up at Circle K and he showed them the way back to his house. He proceeded to yell at my daughter telling the police he hates her. His 1st grade teacher said she can no longer have him in her class. He is terrible, he eats pencils, tears up books, chips up the walls. Two yrs ago his primary care said he is ADHD. I think it is much worse. He is very, very smart. But you never know when he'll act out. He doesn't play with other children. Sometimes when you look at him it's as if he's not there at all.
