Gee, you poor thing. That's a lot of dirty nappies! I don't really have the answer for you, but I would guess that it's diet related, and that it will settle down. It would either be the quantity of food, or the types of food. I think fruit can cause more dirty nappies - does he eat lots of fruit? I really don't know what to suggest, perhaps you could ring the MCHN - I am sure they would be able to give you more information.
