When I have my first success I usually use the same guy everytime, checking and unchecking his task. Then he is building points in Parenting (as is the woman) I look for those not much good at anything else, loafers, maybe a builder who just wants to goof off and not stick to a job. Then, later when he reaches 50 you can help him get a masters in parenting by just kissing all the old women. May be in VV3 they can also tell stories to children for points. I've had several parenting masters, sometimes a female who that's all she does, birth babies, and they are pretty quick at it.
Depending on where you are, they aren't going to make babies unless you have an adequate food supply and a cabin for more population. I think it is the small cabin just below the science table that is quick to build and when complete it rewards you with higher population capacity. Keep the kids busy with mushrooms for food, and collectibles for tech points. The repeat ones are big big points, 100, 250,500, some 1500 tech points.
