This is by far the best book I've found and used to get my 3.5 year old to read. I started with 1 lesson a day, and whilst it took some time having a 3.5 year old listen and sit still for even one lesson, I eventually got to 2 lessons and now he looks forward to doing his lessons everyday! I now have a 3.5 year old who can read and this book made it happen! I just wish the author could make another book to build on this knowledge for kids to keep learning! Highly recommended!
