definetly the high knickers.. and some pads to put there for comfort for the first day or so if the hosp doesn't supply you with any.. they are also great for when you come home to stop your belly sweating.

and if possible a hair drier to dry your wound with.. otherwise you stand there gingerly patting it.. It isn't painful but you will be very wary of touching it..

baby wash as well for yourself.. its very gentle for your wound..

A book.. there will be times when you can't fall asleep and sometimes just starting to read a book will put you right off to sleep.. Make sure it isn't a good book

Definetly your own pillow.. also great for if you need to cough.. hold a pillow against your tummy
