Pregnancy, Take Two

The memory of spending my first pregnancy with my head over a toilet bowl was still very fresh when I found out I was pregnant again. And before I even had a chance to worry about morning sickness, I was turning green -- not in the privacy of my bathroom but at playgrounds and sing-alongs. The morning sickness was no shocker, but what did take me by surprise was that this time it didn't really faze me. While I holed up during my first pregnancy, now I was on my feet, chasing my 2-year-old from sunup till sundown -- morning sickness be darned. It helped that I'd learned a thing or two my first time around -- what to eat, what not to eat, where to stow barf bags for easy access. Most important, I'd learned that the discomfort wouldn't last forever and that it would be repaid a million times over with a perfect, precious little person.

Your second pregnancy may not be the thrilling adventure that the first pregnancy was, but it can come with its own surprises.
