My parents were 24 and 28 and had been married 4 years -- they were both finishing up college (it was just after WWII).

They waited a bit longer than most of their friends to start having children.

I don't have kids, but my sis was 41 when her only child was born. That's not what she wanted -- she wanted to have children in her early thirties. But she was not in a good relationship then, and later she had several miscarriages.

She looks younger than her age, but she says she still feels out of place among all the younger parents of her son's classmates.
