Here is some scary two-under-two math: two pregnancies in two years = 50 pounds.  What, you say? Didn't you lose the baby weight the first time round?  Well, no, actually, it would be mathematically impossible, since I was pregnant again by the time the big one was just four months old.  So back to the equation:  two pregnancies at 25 pounds each = 50 pounds.  That's heavy. They say 9 months on, 18 months off -- so does that mean that it will take me 36 months (3 years) to be somewhere in the vicinity of the weight at which I started?  Daunting, to say the least.  I've been thinking about this for a couple of days now, and I still can't quite wrap my brain around it.
