There is a book that L. Ron Hubbard wrote about the raising of children called Child Dianetics. My parents applied the data in this book to me as I grew up... and I like to think that I came out all right. Here's a quote from Child Dianetics that I think is really cool:
"The sweetness and love of a child is preserved only so long as he can exert his own self-determinism. You interrupt that and to a degree you interrupt his life." - L. Ron Hubbard.
