Here's my list in addition to that:
toothbrush
deodorant
hair brush
laptop/tablet/phone
heating pad
toiletries
cell phone charger
Comfy sweat pants/house dresses
Soft bras
Big hoodie for the drive home
Chapstick
Extension cord for all your plug ins
a large pair of panties so nothing chafes incisions.
small travel pillow for ride home
slip on shoes
trash bags for car in case you throw up on way home
Putting it all in a small carry-on so husband just has one piece to keep with him while he waits...
FINGERS CROSSED FOR ALL OF US!
