Hi there. My 4 year old son is always hungry. Like always. He eats and eats and eats and is always saying he's hungry. He's a normal weight for his age. A typical day he eats weetabix, biscuits, fruit, cookies, Barney bear, dunker or a sandwich, grapes, nuggets and stars, pudding then still wants more. !! It actually bugs me how much he asks for food.
