My mother purchased a copy of this book in 1965 when I was an infant. Mom implemented Dr. Doman's gentle art of teaching and by the time I was two I was reading from Little Golden Books. It's no wonder the kindergarten teacher surprised I was reading at a 1st grade level at the age of 5 years.Fast forward to the 21st Century, I am now a mom with an infant and I too decided to implement Dr. Doman's gentle art of teaching in our home and viola! Our child who is now 5 1/2 years is reading at a 2nd grade level.The bottom line is the principles in this book really do work. The teaching method is gentle, easy to use and it is fun for both parent and child!
