My cyber-friend Christy had a miscarriage on January 4th. She is the mom of Elias, who was a micro-preemie, barely 2 pounds at birth, who is now a beautiful 3-year-old with numerous physical challenges. Christy has two uteri (yes, plural of "uterus" - sounds weird, doesn't it?) and knew this pregnancy would probably require bed rest and many precautions. But she didn't lose the baby because of any physical or medical problems, she lost the baby just because miscarriage happens to about every 1 in 4 women, just one of those statistical anomalies that happen.
Which doesn't make the loss a damn bit easier.
