I disagree my 21 month old son is 2 stone 13Ibs, he is also 98% for his height, his diet is soy milk and root veg, and nothing more, diet isn't everything!.
My 5 year old is 2 stone 11 Ib, he eats anything and everything, take today for instance, fresh banana and strawberry smoothie, porridge milk, with whole milk and blueberries. lunch was cheese stick, fresh strawberry yogurt, and tuna mayo, and sweetcorn sandwich, evening meal was Sunday dinner, beef, yorkies, cali, broccoli, peas, carrots, braised cabbage. and chocolate buttons for dessert, as followed with a glass of whole milk.
ds2 is always homemade meals, and ds2 is mostly die to high metabolism, weight doesn't necessarily mean a "bad" diet!.
