I am a father of two boys and a new baby girl. From talking with my wife over the last 8 years, I have gotten the impression that my understanding of girls and women is a bit skewed. In this book, the author expertly shares his experience as a father of two girls, identifying 7 key areas to focus on in one's relationship with his daughter (or in my case, my wife, too): protection, conversation, affection, discipline, laughter, faith, and conduct. Great stories, practical advice (and not too many ideas), and fatherly exhortation.
A few of my key takeaways: the importance of spending time talking in the car or at a restaurant, or even just spending time together; good advice on dealing with suitors (interview them, but always approve); train your children how to respond when introduced to new people; consider giving more but lighter spankings rather than few and hard. That's probably not a very impressive list, but it is what I remember. A review of the book in the future is in order.
Note that I read the updated edition (2014 versus the original 1996), which I think includes quite a bit of revision based on his adult daughters' input (I think they might be grandparents themselves, now) and changes in technology in the home (cell phones and social media). I actually would take a more conservative stance about technology than he does, but he does provide some good and helpful advice and guidelines.
