MOST essential baby stuff for 0-3 Mo??

If you had to write a concise list of things you NEEDED/were essential during first few months what would they be?

Trying to be super minimal since we might be moving in the meantime and don’t want to over do it before moving lol

And if u can write amount as well. For example, onesies: how many can I get away with buying where it won’t be excessive but I won’t be cursing laundry-time LOL

Also she is due in March (so will be cold at least in the beginning)
