I had a great start with 3 women and 2 men, but strangely the first 4 babies born were boys. At this point I'm a bit concerned, because my females are all over 40 and my males are getting closed to 50. When's the end of "breeding"?

I did get two girls finally, but there's still a 10 year gap with boys/girls. I'm hoping it won't cause problems.

Some games seem to have an imbalance in the gender ratios early on, but it usually resolves itself as the game progresses - sort of like real life. You just never know if you're going to get boys or girls, and the villagers don't have ultrasound technology! The way the game works now, breeding is possible as long as the villagers are still alive!

hehe, I have three "undetermined" children right now. Luckily enough, the first born are finally starting to work, so I can keep the women in kids without worrying about food.

in a slightly related question -- Housing seems odd. I had to restart once (long story) and couldn't have more children at 7 because of housing. now at 15, I can't have anymore.
If villagers can get up to 65, is there something big coming up for housing? Just curious.

Sounds like you need to encourage one of your villagers to do some building. If you already have a builder, he/she may already be working on this...but you won't be able to increase your population until the construction is completed.

Is it possible you might need to do more Building research? I haven't gotten that far in the game yet, but that's my guess if you've already completed all the building sites you can see.

A housing shortage will trigger the construction of another hut (up to 3) if you have villagers who know how to build. Construction research helps solve puzzles.

I have had several couples getting "it" on in the huts, but no kids. I don't get it. They are spending all of thier time clearing the blockage of the stream.

Children are not produced on every trip a couple makes to the hut. Just keep trying!

AH! I jsut dragged a 63 year old woman down to a new hut to celebrate (I didn't think that she'd make it) and accidentally dropped her on a guy and in less than a second, she was already going indoors. Of course, I stopped them since I didn't even know if the old girl was going to be around for another two years. But when I set her back down just below where she was, she had a baby in her arms! Now I have a 63 year old woman nursing a new born baby while her already red health bar continues to decrease! Poor little baby, I'm not so sure s/he'll make it to two.
