how much newborn/0-3 month clothes do I actually need?

X

I’m due with a baby boy in 3 weeks. I bought a huge bundle of baby clothes off Facebook marketplace for $35, so we’re pretty much covered from 6-18 months as those were the sizes included, with a few 3-6 month items. However, that meant we still needed items for when he was born and those few months after. Idk how fast he’ll grow so really just trying to focus on those first few weeks when I won’t be able or ready to go out and get other clothes if need be. I don’t want to waste money and buy items he won’t need. He will be going to daycare everyday starting at 3 months, so he’ll need normal clothes after that, but early on he should be good in just a bodysuit or sleeper.

How much realistically should I plan to have now for him? What’s a good number of onesies, sleepers, pants, etc?
