Don't forget that your peeps can die at any time, though 60 would be about correct. If I'm correct the oldest peep is VERY old, though that was done by mods or something. The children can come back when one of the parents die. You have to choose one of your peeps to enheiret(sp?) when the last parent dies. And to tell you the truth, the Baby Boost isn't the only thing that increases the chances of having (a) new child/ren. If both are healthy, that increases the chances just as much as the Baby Boost. If you are lucky, you can have (a) peep(s) with (a) parent(s)over 50, but the chances are low.
