Baby #2, 9 1/2 weeks

I just looked up on babycenter.com to learn about what's going on with the new baby. Sadly, I have not been as diligent at following this baby's growth like I was with Wright. I found out that as of this week, the baby is about an inch long and the size of a grape. What I want to know is how is it possible that a baby this tiny is making my stomach pooch out so much already!!! I look like I have been drinking way to much beer :)
