that list is pretty complete - i would also take flip flops for the shower ,chapstick, nursing pillow , extra bottoms for lounging around , comfy outfit for you to go home , lanolin
Dan says take pain relievers for Steve they won't be able to give him any from the hossy stash :) also maybe reusable water bottles for you both :)
The hospital will always have the baby swaddled and wrapped, so you only need to bring a blanket for the ride home (or sentimental purposes). The hospital will also have these really sexy mesh panties for you, and I preferred them because I didn't have to worry about bringing any (you'll still probably be maternity size) and I could throw them away. The same with pads; they had a whole package of them. I would also add magazines and DVDs -- nothing heavy; just something to distract you in between contractions. Oh, and don't forget phone chargers.
For your going home outfit, don't bother with regular clothes. Keep the maternity ones handy. Trust me.
