According to my own mother: nothing ...

Thank you Mom in passing ...
But lie !!! This book is ideal for small hands as his super plasticized pages withstand the worst manipulations and nice bright little story of the little chick who dream of having another granny than his, too exuberant for his taste, and of course eventually find when even his super cool grandma (while this is a chicken! ...) is often chosen by my awful for the great evening reading time.
So Mom, you know what? Ben squeaker like!
