I am really worried about my nephew. He is a very kind loving boy, but I think he has behavioural issues. He is always biting his school ties and my SIL buys a new one every month! He is rather obsessed with machinery - he loves washing machines, clocks and fans. He speaks so fast he almost trips over his words and he often repeats whole chunks of adult conversation right down to the last word. I know my SIL is concerned for him (my brother doesnt think there is a problem), she says he doesnt really fit in at school and is often easily lead astray (my dd goes to the same school and says everyone thinks he behaves oddly - apparently he is always pulling his trousers down in the playground!) His school has talked about statementing him because he is struggling with his work and they think he would work better in an intimate setting, but they haven't said anything to my SIL about his behaviour!. What do you think and what should I do. My mum and I really want to help, but not sure what to suggest.
