Hmm, I was asking because my gynaec told me that it's never gonna go away how much ever I exercise. :o
She said "Get a tummy tuck after the 2nd one" LOL.
On the other hand, maybe I can use it as an excuse to not wear sarees when I'm with the in laws :D
How long has it been sicne delivery? If not, try one of those cinching thingies that you are supposed to wear after birth. It should help with the healing and re-firming of your tummy. Good luck!
It takes a lot of hard work! You'll always have a little extra skin and unfortunately it'll jiggle if you jump up and down... but I take my (rather large!) jelly belly as a personal reminder of what I've been through to make 3 gorgeous little men :)
