She might be ready to wear the next size up full-time. I always noticed that my baby was ready to go to the next size when he and she were consistently leaking through diapers. Pampers does seem to hold better. There's a type of Pampers - the box says 12 hrs control on it or something like that.
I didn't think they make the Goodnight diapers in the small newborn sizes. I tried looking for them once. I think the smallest size I saw was size 4 in those. I could be wrong -- it could've just been that store's inventory at the time.
