so many things..

Alot have been said..

Use a maternity pad against your scar to minimize sweating and rubbing ( when at home a hair drier on low setting is a nice way to dry it after a shower)

Walk as much as possible without over doing it.. Stand as upright as you can.. Try your best not to hunch.

If you have to cough or sneeze hold a pillow against your tummy

Ask for pain relief.. One they gave me with my last c/s was a bum suppository.. very embarrassing but gee it worked wonders

oh and when you stand for the first time it hurts but breathe and keep repeating it is all good it is all good.. The First couple times you stand it hurts like buggery but if you just remember that yes it is going to hurt but breathe your way through it then you should be ok.. I wish someone had told me that before my first c/s.. I was much better prepared when I had my 2nd ..

Good Luck
