how many diapers do we need?!?! LOL!

Sh
First time momma here. I am 20+4 and my husband and I want to start buying diapers and wipes, just to start preparing. What size do I get and how many of each size? And how many packs of wipes? Also, what brands would y'all recommend of diapers and wipes? I guess I should know this stuff huh? 😂
