slippers
(i went to hospital via an ambulance, dressed in JUST my dressing gown, and didn't have slippers for the entire five days i was in hospital. Many times, they would have been really useful).

even if you don't feel like eating fruit, or the little packets of cut up fruit in juice on the meal trays, when they are brought to you, store these things in your bedside drawer, for times you DO feel like a snack. The first bowel motion is a milestone after your c-section, so if you can bring it on naturally (by eating fruit) instead of having to take medicine (or have a suppositry), that's one less medicine to take.
