AGAINST
I would have called this book "60 Tips Montesseri" rather than "60 activities ..". Moreover most of the advice seemed logical and natural to me when you are parent.
CONCLUSION
I think that people who know the Montesseri pedagogy will be a little disappointed. As against it is ideal for those new to this approach, and then open up to other books (The child / Awakening, flourish, encourage the child: The Montessori home / Teach me to do alone: The Montessori explained to family)
