I was really, really shy. My dad used to drive me for an hour and a half to go training. I used to finish school, jump in the car, come back, and go to bed. I missed out on socialising with my friends when I was a shy child anyway.
It's really hard to figure out what they need to know. And that's parenting, in general. It's hard to figure out what would benefit your kids and what would just make them needlessly frightened.
