Query: Trained two sons 24 years ago

I used this book for my two sons over 24 years ago and now that I have a grandson I was so happy to find it again. I adapted some of the book to my convience, but, I followed mostly every other part. My first son was trained by noon time, but, my second (and very stubborn) son didn't give in until almost 5pm. I never had to put a diaper on them again! Yes, it is a long and time consuming day but it is so well worth it! My boys were so proud of themselves too.
