i would also consider a pillow, chapstick and your vitamins too
Movies. There's no way I would have been able to concentrate on a book, and I'm an avid reader. We had a couple movies on our laptop going as background noise. And an exercise ball if you happen to have and use one.
Blow dryer,toothbrush,shampoo,soap,undies,pjs,hair brush,pads(overnight) & baby...just maybe couple outfits,toboggan,my hospital gave diapers but few just incase,wipes and socks.
I found just a change of close for both you and baby and some disposible underware and pads. Pack something to read if you planning to stay for a couple of days.
If you have a partner no need yo pack too much. Make a use of him ;) lol
