My baby only wore newborn clothes a couple days. He was 9 lbs when he was born. 0-3 month clothes lasted maybe 2 months.

Depends on how big the baby comes out i bought all 0-3 months my son came out 6 IBS 14oz i had to go buy newborn because he was floating it in and he wore newborn for a few months he was born in October and wore newborn all the way to the first weeks of February

and honestly... buy as much as you want. a baby doesn't typically stay in one outfit all dag long. some go through 5 or more a day.

my baby was never in newborn and outgrew 0-3 month clothing by the time she was a month and a half old. she migjt be an exception though. she was 10lbs 9oz when she was born.
