K.V.
Sounds like everyone has given you a list of things to pack - my only advice would be to pack sooner rather than later. Both my children were vaginal births but were early as my water broke in the night. The first we hadn't even packed yet so were doing that before leaving - LOL! The second I packed earlier and still had a a few things I wish I had thought of.
Anyway, I know you are having a C-Section. I would pack early anyway. I had a friend of a friend who was scheduled for a c-section and ended up having a VBAC as her baby came 2 weeks early and was almost born in the car on the way to the hospital. There was no time for anything! They were all fine, so not telling you this to worry you. I just think the earlier you pack the more likely you will be ready for whatever comes at you ! Best of Luck!
