diaper advice

i’m a first time mom (and a teen mom at that haha) and i’ve put off buying diapers because i don’t know how/what i should buy! i’m at 39 weeks so i’m stressing out about it. my main concern is what brand of diapers to buy. should i buy small packs of multiple different brands to see which work better for my baby, or should i go ahead and just stick with one brand and buy big boxes of that one brand? same goes for wipes. i’m just scared that i’ll end up buying something that my baby doesn’t react well to and he’ll end up with bad rashes or something like that. any help is appreciated! thanks ladies❤️
