Times have certainly changed! I was 31 when I had my first baby in the early 1980s, and like trisher I had "Elderly Primagravida" written on my maternity card. More than once, including in the delivery room, I was asked why I had left it so late to start a family. Now, starting a family in your thirties or even forties is not thought unusual, and even women in their fifties who can afford IVF have done so. My daughter recently had a first baby at 34, and nobody said anything to her about her age.
Mind you, women seem to be thought "elderly" far earlier in those days. I married in my late twenties, and my mother had almost despaired of me. Most of my classmates were in their late teens or early twenties when they married. If you weren't at least engaged by the time you were 25 your mother's friends were dropping hints about missing the bus if you weren't careful. Thank goodness attitudes have changed now!
