I only have one 56 year old female left and she isn't getting pregnant. Are there any suggestions or should I just deal with it and start over again? So frustrating....

I am pretty sure that I read on these boards that woman cannot get pregnant after 50 years.

that is correct

there are events that can bring additional villagers to your tribe though

Sorry to say that after asking for suggestions for improvements for making VV2, one of them was that people didn't think it right for 70yr olds to still be making babies. So in this game they have the menopause at 50 they'll still go in the hut just for fun but there's no chance of any littles ones as a result your only hope is if an island event bring you some in a barrel or something or you're just gonna have to start over

oh ok--women that age having babies is a little weird. I guess I'll just have to hope that I get a few kids in a barrel or something. Thanks anyway

I've also noticed that it's hard not to, when there aren't very many child bearing women, to not end up putting siblings together. I hope with the next chapter more initial villagers are available.

Except that a fundamental of the game is to get a tribe going from a minumim number of people
