My son is 6 yrs old with Autism. When he is happy, excited, mad, sad, he bites his hand.
Basically, when his sense's overload, he bites himself. It has gotten to the point of leaving scar tissue. It seems he does not even feel it when he is doing the hand biting.
It is sensory, like he gets something from it. Also, only does it on his right hand, never the left.
It seems an impulse, he does not even have to think which hand to bite, always the right.
Any ideas on how to minimize the hand biting, or how to re-direct this behavior ??
Any ideas are appreciated
