I went through one box of the newborn and 4 boxes of the size 1 for our daughter. I if you want to stock up I'd say stock up on the bigger sizes. Even of when the baby is born they don't fit they will obviously grow.
I would get a small pack of newborn and then stack up on everything else. I had a box of newborn but my daughter was so small I had to get a pack of premies an she used new burns for a month or so
thank you so much! this is very helpful
ersonally from my experience I would get size 1 I purchase new born Pampers.. tons of them before the baby was born only to find out that when he was born he couldn't fit into new born he was size 1 from the start unfortunately I had opened all the newborn diapers and stacked them up in a cute diaper holder so I couldn't even return them. I would say size 1..plus a little bit bigger is better than too small
