What you are about to see looks like documentation of abuse.
But we didn't do this to her. I promise. She's doing this to herself. With her teeth.
Joy's such a sensory kid, plus she's got a ridiculously high tolerance for pain, plus she's recently stopped grinding her teeth when she stims, plus she has a lot of therapists filling up her days for the past couple of weeks. I think there's something in these aspects put together, with some click of some internal switch, that has resulted in Joy chomping on herself. She does this particularly when she is angry or frustrated, as in "Come on Joy, let's go change your diaper." I try to take her hand, she doesn't want to go, and all of a sudden she's dangling from my hand by one arm and her knee is up in her mouth and she's biting down hard. It's clearly enough to make her feel pain at the time, as she lets out a loud wail when the bite stops.
We've been trying to offer alternate chewing stimulation with therapy chewies and good chewy food. It would be great if she'd re-direct the bite into a chewy-toy instead, but she strikes like a snake and there just isn't time to insert a chewy in between her teeth and her arm.
Jeans and long-sleeve shirts would blunt things somewhat, but we've been topping out past 80 degrees with a lovely bit of late summer weather.
She's done some biting of adults too, but usually we can get out of the way. When the biter and the target are the same person, though, and she doesn't want to get out of the way, you get the results that you see in the photo.
Joy's occupational therapist is making inquiries as to whether the Wilbarger "brushing" protocol might be applicable for this situation. We used the brushing/joint-compressions back when Joy was not quite two years old, and aren't sure it was a lot of help back then. We need something to try now, though. Maybe brushing is it.
Meanwhile, if anyone else has dealt successfully with this kind of thing... let us know! We could use some positive thoughts / vibes / prayers on this, too.
