My 4 year old is 15kgs. I'm not at all worried about him. He's a very physical, happy healthy little man. He eats and drinks and uses the toilet like any other child his age so that's why I'm not at all concerned about his weight, but his diet SUCKS! I think he's the fussiest kid I've ever some across (which is why I slip vitamins into his daily juice to make sure he's getting enough good stuff ).

If you are concerned, give your health nurse a call. They'll be able to lay your fears to rest or send you on to someone else for some help.
