Yet Filliozat invented nothing either, it is a lot of common sense, and yet everyone should read this! Listening to the child, emotions, all agree ... The whims do not exist, especially among toddlers ... The child must be heard, even (especially!) In its anger or sadness ... that's what she explains in her book, simple yet beautifully written. I can only recommend it to all parents or prospective parents. You need it !!!
