Spinoff of winniebee's thread- of the items in your hospital bag, what did and didn't you end up needing? I'm generally a light packer but I still had some items I could have left out.

Needed:
Toiletries- same stuff I pack for any night away
Change of clothes to go home in
Outfit for baby to go home in
Kindle & iPod (for my induction where active labor didn't start right away)
Big water bottle
Planner/notebook
Snacks
Phone/charger
Camera
For DH- swim trunks for when I was laboring in the shower

Didn't need:
Maternity nightgown- wore hospital gowns the whole time
Socks- wore hospital socks
2nd change of clothes- don't know why I packed this
