Comfy going home clothes for you, missing bra if you're nursing or just a really comfy bra, toothbrush, hairbrush, contact stuff etc that you would take on a normal overnight thing, makeup if you want it for after birth pics, pads for after birth bleeding, flip flops or slippers to wear if you're going to walk during labor, camera, baby clothes, a baby blanket, diapers (they might give you some at the hospital...), your baby book if you want to get their footprints in it.
