Wow. Thanks all for your replies and discussion of the background issues. Sorry to have posted and run - took my 3 boys out for fresh air, running and rolling down hills.
DS is 6, and the oldest in his class.
I don't 'know' he doesn't have any SEN, but I am cautious about the label. FWIW, the teachers HAVEN'T diagnosed him or attempted to and I didn't want to suggest they had. But they have suggested behavioural support, and possibly, next if things don't resolve a CAF (?I have no idea what this is...). I feel like this is a slippery slope. I did ask them about whether they thought they were seeing a series of behaviours that added up to something significant. They said they thought they had seen this before as a group of behaviours but didn't want to be drawn. However, I'm not daft, and when they started asking about halloween sweets and e-numbers, screen time and stuff over half term, I put two and two together etc..
They asked how he had been over half term - he had been at a playscheme. Absolutely fine was the answer - no behavioural issues, no impulsiveness or hitting etc.. He did behave VERY badly on the last Sunday of half term but guess what - he didn't want to go to school the next day, because school makes him unhappy...
I have read the NICE recommendations and research on ADHD from cover to cover since our last meeting. And this - as well as lots of other mental health issues - is clearly something which is contested and part of continuum. So I accept that some of my son's behaviours could be described in the DSM-IV manner for ADHD. But then so could some of mine. And his friends'. And their friends.
And isn't that the problem? That ADHD - for example, and perhaps more than other SEN issues - is incredibly tough to classify. The teachers aren't saying this - but they do want to get 'experts' in to observe. I am probably being precipitous but I think once you have a hammer, everything looks like a nail...
Right now, for example, he is sitting quietly, calmly and still watching
Nuzzle and Scratch with his brothers. He sat through his lunch with only a little bit of firm voice from me. He played quite happily with some friends at the park with no aggro. And one of their mothers who I don't know very well but who turns out is a clinical psychologist said 'Don't be ridiculous' when I put the notion to her. He likes to sit and draw. He can play lego (isn't that a 'test'?) and K-nex, following instructions and not throwing things across the room. He writes beautifully: creatively, neatly and with small well-formed letters, is ahead of his age ability intellectually and, like his elder brother, is a pretty talented mathematician. He goes to Beavers (no problems there either).
Yes - he has had some impulsive outbursts, including pure stupidity and sometimes violence at school. I am ABSOLUTELY clear for those who are asking 'well don't you think the school should do something about it?' that they should. As should we: we have done and we continue to both support what they want to do, and work at home on clear boundaries and expectations etc..
