My 10 year old boy is overweight, he's 4"5 and weighs 6st7lbs. He really does look quite fat especially when compared to other boys at his school. The problem is that he doesn't seem to realise that he is overweight or that it is a problem, he just seems completely oblivious to it and I don't know why. Should I try talking to him about it or should I just give him a hint about it ? I'm sure someone will know what I should do :)
