Hospital travel bag, how much do you take? Hot items that helped a lot?
The only things I used were shampoo, toothpaste & toothbrush (they'll give you that, but it's nice to have your own). If you're only staying overnight, you won't even need shampoo. If you're staying two nights or more, pajamas or a robe would be nice for walking up and down the corridor. They'll want you to get up and walk as soon as you can to prevent blood clots.
