There are great lists online. Try bump.com that's where I got mine :)
I packed a night gown, pj pants that were loser fitting, tops, sports bra, shampoo, face whips, tooth brush etc. Phone and camera charger. Snacks and my own cup. I work at the hospital I delivered at and with budget cuts they have extremely tiny cups, gatorade, clothes for hubby. Think that's it.
