the pad on the scar site is definitely just to make it more comfy. stick it to the inside of your undies (if you are planning the higer cut ones rather than low cut) and it puts nice padding on it. i didn't think of it at the time, but then, i didn't have too much pain so wasn't thinking of the scar at all! lol

the tubigrip mentioned is just a circular elastic type band - if they feel a need to apply extra pressure/support they will put it on you. i didn't have any need for it though! be prepared, you may have a drain in when you come out of surgery. it's just to make sure any swelling or bleeding that is happening in the muscles etc is drained away. comes out a day or two after bub arrives. that was probably the most annoying thing for me - that damned drain! i kept forgetting it was there (again, lack of pain meant i wasn't conscious of things) so i'd stand up and go to move, and drop the drain lol. the tubing was long enough that it could hit the floor without hurting me at all.

make sure you pack comfy clothes for your bottom half - i had plain colored pj pants with a draw string so that i could dictate how firmly they pulled on me - they were a size or three too big but so comfy after DD arrived. i also had light trackies - same deal.

good luck for your c/s!
