If you're looking for extra skill points in parenting I think I found a little cheat to get more.

The obvious one is drop an adult on a kid and they'll try to tell them a story, if they succeed they get parenting experience.

The other is if you try and drop a dude on a lady that's too old, I tried like 5 times because the girl had nice skills, but they wouldn't make a kid. BUT the parenting skills did go up each time. Seems to me like after (50?) the women won't make babies anymore. Haven't played with that too much, but seems like a good technique to up parenting skills.
That's also why I was wondering if maybe younger men/women were more likely to make triplets...
any more ideas?

Also, has anyone come up with definite ways to increase the likelihoods of parents passing on skills to children? Is just having master in a skills enough to roll the dice or do you increase odds by maxing the skill. Will having adept in a skill give a chance to pass it on?
