CDs can hold onto the covers of books contrary to what I read in a comment. This is exactly the same stories in books cd sold with a thick cardboard cover (for already having one of the princess and the frog). I bought it for a friend to my daughter, and finally I did offer to my daughter for her birthday. I highly recommend the stories are not very many can listen to the evening with the child too. Otherwise the child alone with the explanations débouille early to know when to turn the pages.
