For my first baby - I packed all the recommended stuff, a tennis ball for my husband to massage my back, mp3 player with calming music, my exercise ball (for sitting on more comfortably), etc. ad nauseum. I used NONE of it. As soon as you are put in the birthing room at the hospital, they'll hook you up to the monitor, and then you won't even be able to get out of bed to pee!
The second time around, I packed an overnight bag with my toiletries and changes of clothing. I also packed a comfortable nightgown with a robe and slippers. I used what I packed this time.
Good luck - childbirth is amazing!
