My twins were born when I was 41. It was the *right* time for my husband and me. What anyone else thinks is none of my concern.
Women are having babies later than they used to, and I think that's a good think. More stable parents makes for more stable families, and that can only benefit the child. I have NO trouble keeping up with my kids. Indeed, I'm pretty sure I'm one of the hipper parents out there....at least that's what my kid's friends all say. I know what's important, and what's not, at my age, and raise my kid's accordingly.
My husband and I traveled extensively in our 20's and 30's (double income, no kids will do that for you), and made wonderful memories. So, we've gotten the best of all worlds. Just our view.
I think we've had the best of all worlds, too.
I had my children in my early 20's. Now, I'm in my mid-40's and my husband is 2 and a half years away from retirement, and we're both still in good health, and enjoying the freedom of having grown kids.
We have money now and can afford the kinds of vacations we never could have taken when we were younger. We frequently find ourselves saying things like, "I'm so glad we had the kids when we did!"
I don't think there's a right or wrong way to do this. Our family has always been very stable and I think we did well by those kids, for all that we had them younger than you. I knew what was important, even back then, and raised my kids accordingly, too.
I'm very glad to have all those sleepless nights and diapers behind me, too!
The one thing I DO tell my daughter, however, is that menopause has a history of hitting the women of my family early. So, she should not assume that she'll continue to be fertile into her late 30's. I was just 35 when I started experiencing the first symptoms of pre-menopause, and I have to assume my fertility probably began to decline at that point (though I didn't test it!). Just something for her to be aware of.
Getting back to the OP:
When a woman chooses to have a child, should be a matter decided between herself and her partner. As long as she has the resources (financial and psychological) to provide for the child, it's no one's else's business. And the
only proper, polite response to anyone's announcement of impending parenthood (even if it's the ninth time around) is, "Congratulations! When is the baby due?" Opinions on the mother's choice of timing, whether she's had too many children already, whether she's too old, too young, and predictions or wagers on the success of the pregnancy, should all be kept to oneself.
After all, what's done, is done. And all babies deserve to be welcomed into the world with joy.
