take clothes you could wear at 6 mths, toiletries, hair brush, tooth brush, pads, breast pads.. for baby take blankets, diapers, wipes, clothes, pacifiers... Just know anything that is recurrences from the hospital goes on your bill, so the more you supply, the better.
I'd say a few onsies and socks they have everything you need there which is the basics I overpacked my first time and didn't use anything but 2 outfits and poor husband had to run up and down the hospital taking the stuff out when it was time to go
