1) the puppets are pets and the page where each animal corresponds to a place where he lives in real life, and the child from his little age teaches the world that surrounds it and knows how to build logical connections, eg "pet - house", "wild animal - forest / wilderness / savannah etc.".
2) each animal is alone on his page. we can offer the child to choose an animal they want, and after his choice from improvise a story.
3) the book is actually a fairly flexible material suddenly the child can hold it in his hands, to do what he wants safe hurt themselves or qq else.
4) in addition to its flexibility the material the book is made produces a specific sound that perfectly serves to attract and then keep the child's attention.
By cons I have a reproach in relation to the design of the puppets themselves. I'm still a little confused because I am not a puppet if a duck is not that of a chicken. This puppet is made so you can not be 100% sure.
