I didn't read through all the replies, so this may have already been covered. But, sometimes it is very hard to tell if a newborn has peed in a sposie especially if it wasn't very much. Also, I thought the pictures on the outside that dissappeared were for the kids to see if they went or not (like they don't already know). Anyway, just thought I'd add those thoughts. We used sposies on our ds, but cloth now on dd.
