Its more where you are in your life at the time. I got pregnant at 24, was single, and NOBODY I knew in my own social circles was even vaguely thinking about getting pregnant. The few who were were wives of bosses and supervisors, having kids at 29-35, and I couldn't relate to them at all.

Wasn't much fun at the time, wish I'd have known that in advance.

Now I've just had kids at 32 and 34 it seems everyone else my age is madly having babies, the complete opposite of 12 years ago.
