What is the oldest villager you have had? I currently have a 50 yr old that says "elderly", but my 54 yr old says healthy.

What is the oldest a villager has to be before she will not have a child? I've had a few get sick with child. I can heal them, but does a villager ever get sick & die caring for a child? I know this is bad, but I was just wondering.

Female villagers can breed until they die. You can look here to see what happens when a nursing mother dies.

And there are discussions here and here about people's oldest villagers.
