My 8 yr old ds will simply not eat, he has only toast, fruit, crisps and chocolate & ice-cream, up until today he would eat shreddies, cornflakes, weetabix but has been getting stomach ache and he says it is the milk, I have tried to explain that he could try soya milk as his brother eats it, but he says it's horrible and will not even try it. He has major tantrums which I think are happening because he is hungry. He has always been fussy but has gradually got worst. Wo should I see about this, I cannot force him and it can be wuite upsetting for everyone, he isn't doing this to get at us he really doesn't like the smell of a lot of foods and of cooking. Any advice greatly appreciated!
