I received useful feedback from Helen Alston, Karin Chenoweth, Tracy Gallagher, Fred Greenewalt, Lisa Guernsey, Michael Kamil, Margie McAneny, Mike McKenna, and Steve Straight. Special thanks to Lauren Goldberg, Kristen Turner, and Shannon Wendling and to seven anonymous reviewers, each of whom provided detailed comments on the entire manuscript. Gail Lovette generously offered consultation throughout this project. David Dobolyi did yeoman’s work on the survey reported in the Introduction, and Anne Carlyle Lindsay created many of the figures. My thanks, as ever, to Esmond Harmsworth for his unfailing support and sound advice, and to Margie McAneny, who took special care with this project. Most of all, I thank Trisha Thompson-Willingham, my parenting lodestar; her wisdom informs much of the approach outlined in this book.
