Much of the book is devoted to explaining why we can’t turn to the experts for guidance, or at least, why we should expect no more from them than from parents or grandparents. As one of the world’s leading developmental psychologists, Gopnik is in a position to state, with authority, that no one knows what’s best when it comes to raising kids. That goes for co-sleeping as well as for screen time and making your kids do homework or take music lessons. Not that there aren’t good reasons for you to choose one course of action for your child, in the context of your situation. But science isn’t going to validate your decision for you.
