I found that I already do some of the things this book recommends - like reading to my children -- but that they also suggested interesting ways to "stop nagging" my kids yet still have them do their homework, ways to help them do well on standardized tests yet face them calmly, and ways to ensure their self-esteem. One thing I found especially useful was two chapters on choosing schools. They give very specific instructions on how to judge a preschool and what to look for when you visit elementary schools. It gave me a list of questions to ask take when I looked at a preschool for my son recently, so I feel now that I can make decisions based on research and not just instinct.
The best thing about this book is that is a good read. There are lots of examples and suggestions for what to do and what to say, even a quiz to give yourself. This is a book I would definitely give at baby showers, because it's a guide you can refer to from babyhood onward.
