I think the EASY method explained in the book is good, it helped us a lot to start with our children. There are practical tips and easily appliquables but sometimes there are somewhat contradictory recommendations, and in the end we do not really know what to think. Apart from the content, I metterai a 0 to the French version of editor. Not only is it very ugly typographic point of view, but also correctors certainly have not done their job. And yes, the page numbering is not the same as in the original release and suddenly, it often refers to pages that do not exist or do not correspond to the desired article.
