I was 35 when I fell pregnant with my 2nd DD. I didn't feel old then, I don't feel old 7 years later, and I'm not planning on being "too old" for anything for, well, several more decades. LOL However, we are very happy having 2 gorgeous kids so that's what being "done" is about for me.

FWIW - there are more mums around who are my age-ish now than when I had my first DD @ 27. Some of them are onto a 2nd batch of kids (ie with older kids from a different relationship), and I think that's evidence that you can't ever predict how life is going to turn out in 5,10, 15 years from now. And the stats say that the younger you are when you start having kids, the more kids you tend to have before you're done. So I really don't think there's any kind of magic line in the hourglass sand.
