This book was written by someone whose own practice as a therapist plunged her into crisis and instead of finding a solution to her problems as a therapist changed course and now lectures as "an expert" so she does not have to suffer actual and real problems of children! She justifies what she does by calling it "preventative mental health." It is not preventative mental health but rather parent education pure and simple!! She has to somehow relate what she does now to her former practice as a therapist! She is being highfalutin by calling parent education as preventative mental health. I would rather recommend Twersky, Adahan or even Winnecott over this book and certainly not any sequel because at least I know that with those other authors I am getting a consistent message.
Nevertheless, the sequel is just as painful to read because of the mistakes in Jewish tradition like informing us that the mitzva of taking the lulav is at night! She utilizes a famous rabbinic trait of citing the source from whom she heard the story, however, to cite a story from the public domain in the name of a particular Rabbi gives the incorrect impression that the rabbi is the original source of the story.
As I said from the outset, the simple psychology in the books is solid; it's common sense: allow your children to learn from their mistakes and experiences and don't shelter them so much. Allow them to experience the consequences of their actions so that they may learn from them. The books' uniqueness of citing the Rabbinic wisdom on the subject is, however, disappointing to one familiar with the tradition.
