Hello,
Since I have had 2 c-sections in the past, I can't really help you on what to bring that will help with labor, but I can suggest some good stuff for your stay (after baby is born)...
I've brought the following the in past, and I plan to bring them again.
-good magazines, a book
-gum/hardtack candy
-lip gloss
-make-up (sounds strange, but it will make you feel better the next day when you look and smell good)
-lotion/body wash/razor
-I brought snacks when I went to the hospital to have my first. I needed a c-section, so I couldn't eat. But, my hubby needed them (make sure he has all the food he'll need while waiting with you).
-slippers/socks
-don't bother bringing your own nightgown-it will get messy (I won't go into details here) Plan on wearing the hospital gown most of the time. A robe is helpful
-ipod
Hope this helps!
