Baby clothes

I feel like I have no idea how MUCH clothing baby will need? I’m focusing on just getting a little bit of NB and more 0-3mo stuff for now but like, does he need 3 sleepers or 10? 5 sets of onsies/pants or 30? I can’t predict how often I’ll be doing laundry haha. Right now I have 3 swaddles, do I need more? Any veteran mom’s with opinions on this?
