Our 2 year old is a really big eater which I've always regarded as a Good Thing.
He eats mostly healthy stuff with occasional treats. Massive appetite though - he'd happily have 3 weetabix for breakfast if we let him, or 2 bananas for a snack.
He is incredibly active. He is quite chunky (average height, about 2 stone).
Is he too young for us to be thinking about limiting what he eats? It had never even occurred to me that we should, at his age, until my husband mentioned it as a possibility. He certainly doesn't look overweight to me, just lovely and perfect - but then I would say that.
