Okay, so here in Canada, hardly needed things. At the hospital they have towels, they have the stretchie panties/undies that are not about a fashion statement but they breath well and you don't care if you wreck em. If you bring your own 100% cotton is the rule.
As for other stuff small shampoo conditioner bottles, your preferred soap bar, Toothbrush and small toothpaste, whatever make up will make you feel human enough for some visitors. I wished last time if brought a portable large mirror, as getting to the washroom after c section wasn't allowed for a while. Comfy clothes are a must, I found my maternity track suit was all I wanted to wear. Now keep in mind it was winter. I wished I had brought cozy blanket and pillow, the hospital stuff sucked.
We brought way too much for baby, they supplied everything except clothes. (bottles, formula if needed, bath wash, vasoline, diapers, comb, etc) we came home with an excess.
