No, not challenging it. It was well deserved and he's lucky it wasn't longer!
How do I get through to him that he just can't attack people?!
When he's calm, he knows that. I've done comic boards, social stories, role play, happy and sad puppets! the lot. I constantly reenforce appropriate behaviours. When he's calm, you can ask him what to do in a hundred situations and he can tell you.
But when something happens - all that work means nothing. And I know that's par for the course, I know it is, but there must be something, some behaviour modification, something I haven't thought of yet.
He's verbal after a fashion, insofar as he can physically speak. He doesn't communicate well though. Mainly echolalic and communication limited really to making a statement to communicate something he needs. His communication is so limited. He couldn't really explain why he did it and he can't really explain his feelings beyond the basic happy, sad, angry.
I know exactly why he did it. I warned them that he was going to be very challenging today. He was supposed to go on a trip today but it was cancelled at the last minute. He spent two hours last night sobbing and screaming - so much so that he burst blood vessels in his face, and when they called me yesterday pm to tell me it was cancelled, I told them then they could expect a hellish day. He doesn't do change.
He was apparently swearing and stimming and very disruptive all morning and then just turned round and poked her right in the eye.
