Those who follow the blog know that Alex had a difficult year with a lot of behaviour issues at school last year. So far this year, he's had two days with significant number of headbangs (more than 3, which I would consider the expected limit for a very bad day). Two out of five is not a reassuring total.
Hopefully this is something of an extinction burst, where he's trying to see if he can get the teacher and EAs to back off the number of demands that they make of him. After all, it was a very successful strategy last year (from his perspective).
But if it is an extinction burst, that makes it even more critical that everything is consistent. Otherwise, we're only teaching him to escalate his behaviour to get what he wants.
I have a meeting tomorrow to discuss it with them. I don't like confrontation, but at the same time, I did the "wait and see/understanding" route last year and the problems only continued. This year, I have to be more active.
