My 3yo son and I have really enjoyed working through this book. The activities have been fun for him, and he has gone from ready to read to a beginner reader. We tried to do a little each day, and generally got through 1-3 pages, depending on his focus on that day. He is extremely proud of his progress and has started to read some very easy books. I looked through a few learn to read books, and this was by far the best for the level he was at. My only issue is that a few of the pictures were a little abstract for a 3yo, but it wasn't a frequent issue and doesn't take away from my love of this book! I wish there was a level 2 because I am having a hard time finding something suitable for our next steps!
