Not all is lost. Imagine my surprise yesterday when one of my children changed the date on the computer and advanced my game 2 DAYS ahead. Luckily food was no longer an issue, but I ended up with 4 villagers who were only 10 and 5 villagers well into their 50s and unable to have any more children. I found about 15 people dead from old age. Always sad when they die

Now the little ones are now 18 and the one girl is my only hope for repopulating my tribe. Poor girl, she's going to be taking care of kids forever.

If you're far enough advanced and don't need to worry about food and tech for awhile, you can always have both women have babies. It'll put you completely out of work for quite some time, but if you can pop out a couple of boys and girls you should be all set. As long as they don't stave.
