In addition to the above: going home outfit for you, slippers, robe, cell charger.. im also bringing my own pillow and blanket for a little extra comfort :)
All your hygiene products, soap, towel, brush, comb, toothbrush/toothpaste, deodorant, underwear u don't mind throwing away, pads, lotion, lip balm, anything entertaining for you for your stay, like a book, magazine etc, socks, comfortable bra and loose fitting clothes.
For the baby, diapers just in case usually the hospital provides these, but I'd bring a few, a go home outfit, a couple of onesies and a sleeper, birp cloth, pacifier if you're using one, receiving blanket, socks stuff like that. I plan on breastfeeding but I'm bringing a bottle just in case she doesn't like me or the hospitals bottles lol.
