So after 15-odd years of rolling my eyes at the whole concept of a biological clock and thinking it was just a made-up way to make women have kids, I'm starting to wonder if it's for real.

I'm 36. My kids are 7 and 3. Having a third kid is impossible financially, logistically, emotionally — on every level. (And also my husband got a vasectomy when our younger child was a baby.) That ship has sailed.

But lately, I go all gooey when I see a baby, I spend a long time thinking about infants, and it honestly feels like my body is telling me to use my last few fertile years making moar humans. Anybody else had a similar experience? Or am I just being weird?
