I wonder about this too. I’ve had five children, and while I don’t get bigger with each one, I’ve never lost all the pregnancy weight either, not even with the magic of breast feeding, har, har. I typically lose a little at first, then nothing budges till I wean, when I lose a little more. Also, I really packed on the pounds eating for heat. I don’t know what a stone is equivalent to in pounds, but I gained 25 pounds in four months. I’m a little shocked. I’m reconciled to not having a slim teenage body, but this weight is uncomfortable and I want some of it off.
