yeh, u will need the rest. the painkillers are pretty strong too, u will have to be careful with looking afta bubs too, normally u would be put on panadine forte which can make u drowsy, and does go to bubs if ur breast feeding, but if it doesnt make u drowsy its ok for bubs only for a very short time tho, i had a c/sect and was on it then too and my bubs was very quiet for a while LOL
ull have to speak to ur surgeon if thats an issue. but definatly get as much rest as u can and keep up ur fluids, dont be affraid to eat as soon as u can too! ull need the energy!
