Probably 5 weeks an he was 8.7lbs

my daughter was born wearing size 1. she was 10lbs 9oz when she was born.

my nephew has been wearing them for exactly 3 months since he was born and still does... it just depends all babies grow differently... but for sure stock up on some size 3 they will stay in that's size for quiet while at least my niece did.

I suggest stocking up on size 3! the weight range is 16-28 pounds! my daughter has been in them for MONTHS. LOL!

u can take them and exchange them for a bigger size if they r unopened hun

Omg really I have 7 boxes of size 1 @amymabundio
