When actress Geena Davis gave birth to twins earlier this year, her age -- nearly 48 at the time -- became the bigger story. Likewise, a swell of publicity surrounded Elizabeth Edwards, wife of recent vice presidential candidate John Edwards, when it was learned that she too got pregnant at age 48, and again when she was nearly 50.
Soon after, however, both women began to seem like "younger moms" when in November of this year headlines touted the birth of twins to a 57-year-old, single, first-time mom, Aleta St. James from New York City.

3 women, each trying to build a family, have been waiting on some important — and nerve-racking — developments. Will Jody's latest fertility treatment succeed? Will Carrie's labor go smoothly? Read about their latest challenges and triumphs.
Indeed, while the term "older mother" once referred to women who conceived around age 30, today our birthing timeline has moved significantly, with the number of much-older women becoming first-time mothers on the rise.
"There is no question that the age where getting pregnant is considered a possibility is definitely expanding -- we are continuing to push the time line up and up and have been doing so since the 1980s," says Frederick Licciardi, MD, associate director of the NYU Program for IVF, Reproductive Surgery, and Fertility in New York City.
A new report issued this month by the CDC control verifies that a greater number of older women are getting pregnant. The birth rate for women aged 30 to 34 increased by just 4% in 2003, while those giving birth between 40 and 44 rose 5%.
And while births to women aged 45 to 49 held steady (at 0.5 births per 1,000), the rates for women in their early 20s -- once considered the prime age for motherhood -- decreased by 1%.
But just because we can push the birthing envelope, should we? And are we tinkering with Mother Nature in a way that may come back to haunt us -- if not as a society, then on an individual case-by-case, mother-by-mother basis?
Doctors say it's a hard game to call.
"It's not an issue that is going unnoticed, that's for sure -- but right now we don't have enough medical data to tell us one way or the other if older motherhood is a good thing; there just aren't enough women over 50 who have pushed the envelope to give us a clear picture of what happens when you do," says Michael Brodman, MD, chairman of obstetrics, gynecology and reproductive science at the Mount Sinai School of Medicine in New York City.
