Query: Great Concept - Poor Execution

My son loves the books, so when we bought this one, we thought it would be a real winner. We were, unfortunately, wrong. The problem is that it is an activity book whose pages unbind and drop out too easily, and it is not a good size for laying down and writing in or drawing in. Because it is the same size and binding type as the "reading" books, it just doesn't lend itself to being an "activity book".Content is fine and right in line with the other books. I just think the execution is lacking.
