I also had (have) this. After DD was born same as some of you i weighed less than i did before i got pg. My nice flat tummy now had stretch marks and a HEAP of excess skin which i couldnt get rid of, i was told to just do more ab exercise's but nothing worked. A friend of mine was a body builder at the time (this was 3 years after DD) i asked him about it and he said that no amount of toning would shrink the skin. 12 years later i do still have it. I couldnt wait to get pg this time to finally not have that flappy skin dagging off me! I dont know many people who also have this - it was nice to read that you ladies have it as well - thought it was just me!! (my SIL doesnt) I did watch a episode of RPA (or some medical show) and a lady had the same thing - she had a op to get rid of it.
Once i have finished having babies - tummy tuck for me!
