That would make for interesting converation Silver 
A mum at my ds's school is constantly called in re her boy's behaviour. He is 6 and is disruptive, steals, hits, spits, you name it. She works part time, but instead of fetching him home and trying to sort out his behaviour, she pays for him to go into after school care, then umteen after school classes, swimming, judo etc.
Rather than address the stealing for example, she will declare he is a tactile person and has a need to touch things
. So, he touches it and then steals it. She is not addressing the stealing, she provides 'reasons' for it. She conceived her ds as a result of a two week fling with a married man who lives in a different continent. He has never met his dad. When school try to help, she makes a case for ADHD, and yet, when the school start the statement process, she stops and blames the teachers.
Only 6, and the head has suggested he move schools. Not because she thinks he is a hopeless case, or has ADHD, but because the mother is parenting him in such a chaotic and confusing way.
I think the new findings of genetic causes for ADHD could have a fascinating effect, with perhaps the numbers of diagnosis falling very soon.
