The internets just erased the review I'd been working on at length. This book is marvelous, for parents, for teachers, for policy makers. Christakis knows what she's talking about with young children, and she conveys that knowledge in a thoroughly documented, and entertaining, way. Read this book if you're at all interested in the topic.
If you don't have the time, watch the movie <i>Daddy Day Care</i> in which the previously fond-but-not-very-involved fathers of preschoolers become very involved, by letting the kids take the lead. It's brilliant, really.
