Self-Injurious Behavior

Lately Michael has started to do this when he is in a meltdown. He'll usually start by slapping his leg (he's been slapping the floor/table/wall for months now) but now it is also escalating to biting his kneecap and his arm and hands. The other night he bit his arm so hard that he broke skin. So I decided to get a referral to Children's Hospital to get a full evaluation since the guy at Mary Bridge was kind of a jerk who blew off a lot of his behavioral issues. I'm also going to talk to the ST and OT about it on Wednesday and see if they have any ideas how to curb this. I don't know what I can do since I can't exactly have him voice his feelings. I could tell him all day "we go here and do this if we are mad" but I am 99.9% sure he wouldn't connect the two things and be able to actually utilize whatever I taught him. Sometimes this crap is hard.
