i didnt do it either, i also breast fed though not so much at the hospital or first few days due to the tremendous amount of pain i was in, i was also prescribed percoset, good luck girl, c-sections hurt and suck. Definitly try to take SHORT walks, i discovered keeping a pillow or folded up blanket pressed on it when i walked helped ease alot of the pressure i felt while walking.
i didn't do it- i think the nurses did it once or twice a day and that's it. However, I was breastfeeding, which helps everything shrink back down. I don't know if you are supposed to do it more if you are not bf'ing.
