Medina writes as though on a quest for the universal theorem for instilling success: empathy. He cites work from several great authors (Haidt, Brosnan, Lehrer) and includes many personal experiences. If you are suffering from parenting book fatigue, I would choose this book over Nurture Shock, simply because of the breadth of information it covers. Medina went into much more detail and focused on the younger age group.
Written for the layperson and covering much of which I hope most parents are already aware of. Excessive TV=bad. Empathizing & Friends = good. Highly recommend for all future/current parents that take advice as a learning experience rather than "this is what you need to do to be the best". The chapter on relationships and happy marriages could be an eye-opener for fathers.
The first chapter on pregnancy, while well intended, is not as solid as the rest of the book. Medina is much more of a brain biologist than pregnancy expert. If you ARE pregnant I would check out the Mayo Clinic Guide to a Healthy Pregnancy instead. Good enough to put a few more of Medina's books on the 'to-read' shelf.
