That's really great Jeffswife: well done. I think everyone's so different. That's why they don't really weigh you at every appt anymore. I gained 5 llbs during the first trimester and then another 4 lbs in a week!!! I am eating like a horse though, and my bump has suddenly popped. As long as you're eating well, I don't think anyone really worries what your weight's doing.
After I've had the baby, I'll do what I did with my other 2: breastfeed and lots of walking. It took me nearly a year with both, but that's a reasonable amount of time to shed the weight I think. These bloody celebs out on the red carpet in a tiny dress 4 weeks after the birth need a flipping great kick!
