I have a 6th grader who has SEVERE autism and Down's. He has very few skills and stims ALLLLLLLL day. He makes noise, rocks back and forth, puts everything in his mouth and chews on it or flaps it back and forth, won't concentrate for more than a few seconds, won't sit in a chair, wants to just get out of the room, falls to the floor and doesn't want to get up, and pees more than any person known to man, he just basically wants to be left alone on the floor all day to stim. I am at my wits end trying things with him. His teachers before me have not had any success either, obviously. They have tried a sensory diet, with no luck either. He is almost legally blind due to glaucoma, but he can see things up close. We have started using a large light box to do some of our pre-vocational tasks with him, but he does not want to concentrate for longer than a few seconds. He takes meds for his glaucome but can't take other things that may help him due to those meds. Any ideas where to start? I have been looking for ideas online, but have had no luck finding anything remotely close to the severity of his disabilities. I would like him to stop stimming as much and chewing on things as a start. I think once he can get past that we might get somewhere.
