I love this book even though I find it a bit fragile for children. This is a BD format rather intended the children spent 3 years or 4. The goal is to find the Mr. and Mrs. indicated. A second set of double page makes us look for other hidden elements like birds, mice ... The identification is not so obvious but it is true that the children after 3 or 4 uses remember very well where the characters are hidden. Let aside a time, the book then gets interest.
A hardback would have been wiser for the pleasure of playing only smaller.
