Yes, Steve, chapstick is a necessity. Of course, I have it with me at all times normally, so it wasn't a big deal. Other than that, I had my toothbrush, a comb, which judging from my pictures, I did not use, and socks, because those are almost as important as the chapstick. I stayed in the hospital gown too because I figured it would be less laundry for me to worry about when I got home. I tied it closed securely for walks, but believe me, the nurses could care less about you mooning them. Just don't scare the visitors while you're doing it.
I tend to travel pretty light for hospital trips anyway because they have everything there - soap, toothpaste, combs, etc.
I think the thing I appreciated having the most was a picture of my kids. And fortunately, the hospital was not far from my house, so if I needed anything, my husband could have gotten it for me.
