In VV3, the women stop having babies age 50 (the men can do it until they die, but if you don't have a woman under 50 that doesn't matter anyway).

.....but there are island events that can bring more people to the village, and I have seen one that makes a woman have a baby (and when it happened to me, the girl was only 14 so I don't think that event is governed by age!)

Maybe you'll get lucky with the events!
