My lil brother is 10 and he is so fussy as he refuses to eat any fruit or vegetables. He eats mashed potato and roast potatoes. He occasionally eats beef casserole and beef, lamb and chicken. As for snacks, he eats crisps and chocolate brownie/chocolate related treats. He likes typical child food like fish fingers and chicken nuggets. He also eats 9 f.fingers and chips OR 10 chicken nuggets. He does PE at school and has break and lunch so he does run around but not much. In 4 years he has grown just under 12 inches. He is startting to look a bit rounded and my mum and her bf aren't active. When he sees my dad at the weekend he eats just as bad and sometimes goes to the park but doesn't run about much. When my husband and him ran around at our local park, my brother got tired long before my husband. Any thoughts??
