Some babies never wear newborn diapers. The hospital didn't even have them available when DD#2 was born! They just used size one, and folded down the front so that it wouldn't affect the cord stump.
I had one pkg of NB and one of size 1 waiting for me at home. I ended up buying several more pkgs of NB, but I don't think most people do. I'd do that again.
Since you've already bought some, if you end up with unused ones, they would be a welcome gift when a friend has a baby.
I use Parents' Choice from Walmart. I like them better than Luvs and don't have to worry about the Dry Max chemicals.
