There are so many variables! With my first I gained 38, but I started underweight. Starting out small, I was told by my OB that I would naturally hang on to some weight as I nursed. Sure enough, by 6 weeksPP I had 6 lbs to go to be back to my pre-pregnancy weight.....and those 6 lbs hung around until 6 mo. PP, which was 3 mo. after I stopped nursing.
This time, same deal...started underweight, gained 32, and at 7 wks PP I have an extra 9 above my pre-pregnancy weight to go but seem to have hit that wall. I'm convinced my nursing boobs have to add an extra lb a piece! Lol
With DD I lost it all in 2 weeks.
Since having DS, I have about 10lbs to go, but I gained a little more with this pregnancy.
