I started reading A Book with my son last May when he was barely two-and-a-half, and this quickly became one of his favorite books. Not only is it lots of fun, but the format provides a framework for introducing new books by genre. For example, we soon started reading classic fairy tales to get the references on the pages where the girl in A Book wonders if she's in a fairy tale. We're now starting to read Alice in Wonderland, to get the references on those pages. And of course the pirate pages have been a huge hit all along, not only teaching him how to dress and speak Pirate but contextualizing a recent visit to the pirate exhibit at the Field Museum in Chicago.In sum, it's a terrifically pleasing read -- my son still giggles when the girl looks up at him and shrieks "Eek! What's that?" (Mother Goose: "That's a reader. Watch out, it can read whatever you say") -- with great potential to lead onward to other pleasing reads. What more could you want in a children's -- or any -- fiction?
