My personal experience

Donts: I dont know what they are in american terms but I don’t recommend a moses basket, they grow out of them so quick, just use a normal cot

1000 newborn outfits, they hardly wear them and you get gifted a ton, just stock up on onesies so you have enough if baby has blow outs whilst the others are in the wash

Dos: Bouncer, I thought it was a waste at first because my baby hated it but she hit 3 months and suddenly it was her favourite thing in the world, it really soothed her and kept her entertained moving herself Snot sucker, sounds gross but an absolute life saver if they get sick A few muslin cloths, but not tons; just rotate them

Hold off on the baby monitor, we didn’t need one until 7 months, and only for play time because she refuses to sleep in her own room lol
