I have just had cs no2 and cant wait to start exercising. You sound like you had lots of probs healing? After DD1 i started doing water aerobics from about 6wks i'd just go lightly on the tummy stuff but by 3 months i was doing body jam classes (a dance x aerobic workout) I was 23 when i had dd1 and my tummy never went back 100% i was size 8-10 b4 been pg and got back to a 10-12. This time my cs recovery has been even better than my last. DD2 is 9 days old and i feel fab and already back to my size 10-12. I'd say just eat sensibly, drink lots of water and exercise by all means but start light and then increase it.
