I turned on my game this morning and found the population had gone up to 25, which was a little higher than I'd expected. The reason was that a villager had given birth to triplet girls. They were identical to their mother apart from their dresses. Their mother was the "lazy" clone of another villager, the result of an event.
I'd only just got L3 medicine, and can't remember getting triplets so early in a game before, especially without getting any twins first.
