I think I am in trouble. I am down to one girl that can get pregnant and all the babies being born are boys. She is getting up in age also..

The gender of children born in the game is random, and there is sometimes a gender imbalance as a result. Usually the imbalance is corrected over time as the population grows. If the desired gender of baby is not produced by your villagers, there are several Island Events that can bring additional villagers to your tribe.

YEah I got the barrel of babies..every single one was a boy..sigh

I have actually run out of females. Eek. There's a thread about it here - lone villager. I don't know that it will help solve your problem but at least you can find sympathy

Good Luck!

OK..so now my lone fertile female is pregnant with TRIPLETS so hopefully one is a girl. I have gotten three boys from her already including my first "ginger"
