I liked the first book (happiest baby) although I felt that it could be summarized into an article. The second book, is not at all aligned with what we know about psychology and child development. It gave me insight into what it is that American parents do that makes their parenting so difficult and words of their children so mechanical and hollow, “thank you” “please”. It is punitive for children and exhausting for parents. There are some good things in there but it’s not a book I would recommend to anyone. I much prefer “no drama discipline” which I found much more aligned with current research in psychology.
