My ds is 10 and totally not into any sport despite our encouraging him over the years. He is just not a physical dc and prefers to sit and read or draw or make something. Even when he plays tig with friends he tends to walk around slowly or lean over to tig people! I am starting to worry about his fitness. He also loves his food so I don't want him to get fat. I want to get him more active but in an enjoyable way. Help!
