How in the heck am I supposed to know if I am breeding a child with a parent? it kinda creeps me out. I would like there to be some sort of clue, Sorta like when it tells you "This villager is too young". Maybe there can be something that says "These villagers are related" or maybe they can have clans or last names to help sort them out. All villagers from one family can wear the same color clothes or something.

Just an Idea.
