^^^ and of course a couple outfits for baby and the carseat (: the hospital my son was born at provided diapers and everything else you need. I would also bring the baby book (: I also brought music to play during labor and birth (:
insurance info/registration forms, a comfy robe and slippers, quarters for vending machine needs you may have, panty liners, some underwear, hygiene stuff, something from home that makes you feel more comfortable at the hospital. this is what first comes to my mind ☺
