DS is 14, he has adhd, he is on medication but he still is hyperactive at times. The school is fine with him leaving the classroom to go and sit somewhere to calm down as he can't focus. Today, probably because of the heat and him eating sweets (the whole class was given them and he didn't want to be the odd one out so he ate them) he couldn't focus in his last lesson, he asked the teacher (it was a cover teacher so they don't know him) if he could go to his head of year or the learning support room to calm down and he was told no, DS then kept walking around the classroom so ended up getting into trouble. He told the teacher he couldn't do his work but the teacher told him to shut up and stop being disruptive or he’d be given a consequence (c1/c2 etc and c1 is a warning but the rest are detention etc). DS told me he put his head on the desk to try and behave but apparently the teacher didn't like that either and gave him a c and wrote in his planner that he was refusing to do his work.
Would you complain about this or let it go?
