One can only crack in this book that holds up well in hand, the rounded edges and with children from touching pictures educated with the Montessori method. With a gentle prices (just over 10 euros), and finally we have lots of activities to keep our child, because most books do not Montessorian abound. By cons, yet many times we fall into 30 activities: observe your child, activity 40: Do not interrupt the child ... We come back to the cover, that's it was promised us 100! A little easier anyway, especially as there are so many other activities we saw a picture in the schools, we really wonder why such laziness. The book is easy to read, and it devours but when you get to the end, we would have liked more ... Too bad, it seems to have been taken for children and also we have had Lean reading of a work.
