I am dreaming..Cats ebook

We recently received this ebook in PDF format to download. It says it is recommended for children 4-8 which my son is 5 years old and just learing how to read. I do feel the book is age appropriate and it had a lot of learning information in the story itself. However My son was not that thrilled about it because he likes and enjoys audio, or hardcover books best. It may be best for a child who is more laid back and don't bore easily, as my son is always on the go and it takes something really good to grab his attention. I think the book had a great story line and you can learn a few things from it to. I also think it would be better if it was not in PDF format as we received it. it may be better on a kindle which it is available on Amazon right now. I am still not sure I would recommend this book to anyone in my family or circle of friends. I received this product in exchange for a honest review and opinions are 100% my own and unbiased.
