I bought this one at "first sight" and the beginning was very disappointing, as it repeated the same central idea about parenting a million times (how many pages could have been shaved off?). As I was starting to fear nothing good was to come out of it, it slowly progressed into giving actual matter-of-fact advice and pointers, sometimes mentioning important studies recently done in the field and delving a little deeper - making it a worthy reading in the end, even if the writing style was somehow incompetent.
I particularly liked the case-study used throughout the whole book (Alejandra's story), which at first is so exaggeratedly bad you can't take it seriously, but slowly becomes... Plausible, and incredibly sad. Like the story of the life of so many people you know.
