What baby clothes do I really need?

Ava • Baby boy born in August. TTC rainbow baby

So I’m 16 weeks and I find out the gender next week!! Currently I’ve been buying a bunch of gender neutral clothes enough to stuff the entirety of one Target bag lol. The clothes I bought are mostly onesies (some socks, jacket/onesie/pants set, etc) from NB, 0-9 months.

When I find out the gender what specific clothes should I look to buy? Also how many swaddles do I really need? Thanks in advance 😊
