Ajuma- I don't know, I'll check on that
CasiBK- In my last generation my people had 4 kids. The parents were 48 and 49, so I tried, not expecting anything to happen. They had a kid. The rainbow girl!
I had her take on the house. She is currently 55 and her husband is 54. They're both Box Makers!
They have 6 kids including twin boys! So, In my 35 or 36 generations, that's 7 sets of twins and only 1 set of triplets.
