IMO there are quite a few that ARE TOO SMALL ... and it's not like 7lbs is a huge baby or anything ... be very picky about what you order and ask around. SOme of the ones I bought fit beautifully for a week or two ...others atill fit beautifully (like the muttaqin NB's and the itty bitty buns small that I ordered with an umbilicus cut out) ...by the time Skylar hit 8lbs I had him mostly in smalls (LOVE the girl woman goddess and luxe small testers that I have!!) anyways and he's still in smalls at nearing 12lbs ... I think around 15-18lbs I'll probably have to move him into mediums and that won't be for at least another month or two. I guess what I'm trying to say is that as far as I'm concerned it's a better $ investment to buy small fitteds than NB's because they'll fit just as trimly but over a much longer period of time.
