Babies: I can't get my female villagers to produce children.

The first thing to check is to make sure that there is adequate food and housing. Villagers won't produce children if there is not enough housing. Your population is limited to 10 villagers until the first new hut is completed, 17 villagers for the second hut, and 35 villagers for the third hut.

If the female villager is at least age 18 and younger than age 50, she may just require persistence in order to produce babies. Try introducing her to a different male or set her preferred skill to breeding (if she has some experience) and let her choose her own mate. Females younger than 18 cannot mate. Once a female villager reaches age 50, she can no longer produce children.
