You should get some from some Facebook groups that are pre loved ! They sell some really good ones on their I love buying them there a lot of ppl also sell them like in bulke I bought my first ones from some reselling app that starts with the p I can’t remember the name of it but I do wish I had known about the Facebook groups that resell N before my baby fit into them I just used regular diapers that were gifted to us at the baby shower n from the hospital
Before 10lbs: I got a ton of free diapers (disposable) at the hospital I gave birth at, I used those until they ran out at 8lbs then started newborn all in ones from Nicki’s Diapers and essembly. For your registry: I put a bin and a bunch of different types of diapers; flats, all in ones, fitted. I ended up liking some more than others and put the others as back ups. I also put washing supplies, weewee pads, cloth wipes and wipe solution/skincare stuff.
