I normally use 3 diapers per child per day, but of course it can be up to 5 if they poop a lot (I have some super poopers..LOL). Obviously, if the diaper is dry, I don't change it, but I can't imagine only usng 2 diapers for an entire 9-10 hour day! I know they have improved, but I sure wouldn't want to sit in a wet diaper so why would the kids? That is crazy that they don't want to bring you diapers! Does their child get rashes?
