You need a going-home outfit for yourself unless you plan on wearing PJs. You also need stuff for the baby (not sure if that's a separate list). I would also recommend a soft blanket for yourself and a boppy pillow (even if you're not breastfeeding, still easier to hold the baby with a boppy when they're tiny.
@Emily yeah the baby is a separate list. Babies already packed mostly just mom and dad.
Any more natural pain relief tools such as a heating pad, tens machine, lavender oil, etc. also snacks for during labor to keep your energy up. Water bottle with electrolytes. Things for post partum recovery such as packs from Frida.
Lotion and any skin care products. Hair ties. Prenatal vitamins.
