Depends on your baby. My oldest was in nb for 5 weeks, and he was 8 lb 2 oz. My youngest was 8 lb 14 oz and only stayed in them about 2 weeks.
depends on the baby. mine wore them for about a month in a half. she's been in size ones since 2 months and she is almost 5 months old. stock on size ones and size 2s
Just wait till your baby is born just have newborns just in case @cgaona
so should I just stack up on 1's instead of newborn? @jgarciamua @kee89 @mama_icie
Depends on baby's size and weight. Mines only wore them for the first month. Then they were in 1's for awhile.
Mine didn't wear them at all, came home from the hospital in sz 1
