I just finished a book (my fiance and I are expecting our first child) called the expectant father
facts, tips, and advice for dads-to-be
second edition
the authors are armin a. Brott and jennifer ash
it is the male counterpart to the book "what to expect when you're expecting"
it has a chapter dedicated to every month of pregnancy and at the beginning of every chapter tells what physical and emotional symptoms your partner may be having and then the rest goes on to tell ways to support your partner, get involved, and even things like recipes with good prenatal nutrients. Even though that there are more contemporary views regarding fathers now there still seems to be a slim selection for fathers-to-be. The few pregnancy books for women that offer sections for the father are more focused on whats going on with the partner and the information tends to be very watered down and condensed.
I would highly recommend this book to any expecting father, it covers both what you and your partner may be going through and it is very interesting and has helped my and my fiances relationship greatly.
