I generally have a fair number of girls on parenting duty at any one time, so as soon as an elderly villager dies, one of them will produce offspring to make up the numbers again. Talk about dead men's shoes ... In the meantime they are all busy kissing one poor inoffensive male and steadily working towards becoming master parents. I usually also make the "alpha male" also a parent. I figure that if the girls have all the fun kissing him he ought to be able to do some kissing back.
