Love that photo! She still has a bloody 6 pack under the wrinkles though! lol
I suppose it is about the work you put into it too. I know people with 4 kids who have the podge, the apron, and look quite bad, and others who have a perfectly flat stoamch still ('tis ok, we all hate her too lol) ;p But she works for it and was very fit pre-babies too.

I suspect mine wouldn't look much different to what it does now. I got more stretch marks with DD2 but it was the cs that gave me teh apron, the gunt, and my iss-ewes! lol
