I'm just past 20 weeks and am up 25 lbs from my true pre-pregnancy (pre-ivf) weight. I'm 5'8" and was normal BMI pre-preg. This is right on track according to Barbara Luke's book on multiples, as her research says gaining more at the beginning affects birth weight most. But while my OB isn't yelling at me for it, she's definitely mentioned that I'm on the high side. So I feel totally bi-polar about whether or not I'm gaining too fast! I will gladly gain as much as I need to make these babies chubby, but want to stay healthy too.
So twin mamas, what was your weight gain at the halfway mark? and if you've given birth - what was your total gain and the weights of your babies?
