I have one villager, who I am trying to get to be an elder by increasing his parenting skills. I have had him embrace with an elderly woman for a while.. and I have had him teach children every chance I can get. And still it seems like his skill bar stays about the same. Which gets more bang for my buck?

Also - how much can you train the kids by teaching them? Would it give my tribe a significant edge when they are old enough to work?
