New (old) parents

Earlier this week, I was a guest on NPR's "Talk of the Nation" talking about the ever-expanding age limits on motherhood. (You can listen to the link here.)

According to U.S. Census data, the fastest-growing age group for new mothers is 40 to 44. The poster child for older moms is the woman in Romania who gave birth at age 66. I personally know a woman in her 50s who is pregnant with twins. And just a few weeks ago, I was contacted by someone from Motherhood Later Than Sooner, which seems to be a great resource for older moms. It's a topic that is near and dear to my heart (or should I say ovaries?) as I creep up on the big 4-0.

In fact, as I sat down to write this, two women had this exact convesation over in the next cubicle:

Woman #1: Are you thinking about starting a family?

Woman #2: I just got married, so not yet.

Woman #1: After I was 35, my energy level just dropped. In some ways, I wish I had kids in my early 30s. I'm just putting that out there.

I'd love to hear from Working Parents--moms as well as dads--on this topic. How old is too old? What are the pros and cons of waiting to have kids? And what impact can later parenting have on a career path?
