Great fan of Balthazar soon as I saw the publication of this book I precipitated against then there was no comment. So I was surprised format. It is a book with only 12 medium-format pages with very thick pages foam. We find the usual sobering teaching the child with removable parts we dress, we undressed and Balthazar Pépin we discover with What's in the butter ... This book is generally good but very different from "I learn to play alone" or stories of Balthazar, but néanmois children (2 years and 4 1/2 years) we enjoyed the novelty of detachable parts
