In 1995, Armin Brott's "The Expectant Father" did what no bestseller had done before: It became an accessible, reassuring, and indispensable resource for new and expecting dads. Millions of copies, syndicated columns, fatherhood classes, and radio shows later, the book's fifth edition has been updated with more information, more case studies, more reader input -- and more discussion of the importance of the mental health of both parents.

We talk about how Armin wanted to turn his anger into a force for good, why he joined the Marines to learn Russian, and why you should never tell your drill sergeant how to do their job.
