Quoting Household 6:" Are there any one size diapers that actually fit well from birth? I'm building up my newborn stash now ... [snip!] ... is pretty decent sized so I won't have to worry about it too much when she's big enough for the fitteds and OS I already have."
Not really unless you have a huge baby. Even smaller brands of OS dipes are still way too big for newbs. Personally I am a huge fan of plain old prefolds and covers for newborns. They are cheap and so easy to wash. My breastfed newborns literally pooped like hourly so we could easily go through 30 diapers in a day so prefolds are definitely my first choice for newborns.
