My son was born at 7lbs 11oz. He was about a month old when we moved him up to 0/3. He could’ve stayed a little longer.

Depends on how big your child is when it's born and how fast they grow my oldest was only in newborn for about maybe a month my second child was in it for longer.

Yeah like others said it depends. I got like 6 newborn sleepers, mainly from Goodwill. The littler sizes still look brand new because they don’t use them for long. It’s good to have them than not.

Mine was in them for about 2.5 months. We had mostly just sleepers

I also started buying 1 box a diapers a week at a store that will exhachange boxes if not open (Wal-Mart here) and had 2 boxes of size 1, 2 boxes of size 2, 2 boxes of size 3 and 1 box of size 4. I endes up exchanging alot for bigger sizes but i only started buying diapers like 2 months ago. Lol i aleo had 2 big boxes of whipes.

It really depends. However, I have 4 kids. 2 were born at 6 pounds and the other were born at 8, and almost 9 pounds. All 4 of them wore newborn for at least 1-2 months.

My baby wore newborn for like 2-3 weeks.

Clark only wore newborn for 2 days. So we only got 3 pjs while i was pregnant and 1 small pack of nb diapers but we had 200$ set aside for clothes and diapers just incase he was small.
