This book was recommended to me by a friend when my eldest child was 4. She had a great time going through the lessons- and, the biggest surprise of all- so did I! I have no real instinct or patience for teaching, so the fact that everything I was supposed to say, down to how to correct an error, was scripted for me was my saving grace- Hallelujah!That same child is now 7, in second grade (after skipping first grade) and is in the top reading group in her class. I can only credit the foundation that this book taught for that success!I'm working with her younger sister now, and she loves it just as much. I even bribed her to eat all her dinner one night by offering to let her have another lesson after we finished. :D Our little boy (age 2 1/2) will sit at the table and try to mimic what my current 4-year old is doing. Looks like we'll have no trouble getting him started in a year or so as well. :)
