I'm always conscious of the fact that a book starts, basically, with a kid in a lap, and a parent reading to them. If I'm not at least understanding that the parent's got to be there, and the kid's got to be there, together, then I don't feel like I'm doing my job. I hope that the language or the dialogue or the way characters interact entertains parents - when I'm playing with my own kids, I'm entertaining myself too, as well as them.
