DS is in Y2, almost 7. He has always had behaviour issues: aggressive, short-tempered, talks back, socially awkward etc. Recently recorded incidents at school are: strangled (another child), kicked, hurt with a pencil, hit, inappropriate talk with a teacher etc. He loses playtime for this (extra playtime for good behaviour - but he rarely gets that), I get reported via chart, teacher and headteacher. He will be seeing ed psychologist soon. I personally suspect ADHD and/or Asperger's traits.
I am at a loss how to react at home. He brings back the chart almost every day with various incidents all over. I do talk to him but I feel like I talk and talk and talk and nothing ever changes. I take away privileges sometimes (TV etc.) but not sure if that makes sense, as the school dealt with it already, and to be consistent I would have to tell him off almost every day, which would create very tense atmosphere.
He behaves better where he can relax, i.e. at home, and in theory I should be bringing his positive side out (we started doing sports for that reason). On the other hand, I cannot totally ignore what happened at school. I just don't know what is best. I try hard to discipline him but his behaviour chart shows that we get nowhere. In fact, it seems that the harder I try, the worse is the chart. Then I lose my balance and just decide to let him relax at home, which at least makes him happy when at home.
Any word of advice, please?
