does anyone have any suggestions as to how i get my 10yr ds (severe autism, no communication) to stop pinching himself. he does it a lot when he is upset. hasnt been very well today, temperature just lying about (usually extremely hyper) he has nipped himself all day long, so now his legs and arms are covered in tiny bruises. just as well ss and his sn school know and have experienced him doing this as he looks like a battered child. its upsetting for me to watch him hurt himself, just keep taking his hands away and saying no but 2 minutes later he does again.
