Being that I was experiencing a particularly difficult time in my child's life (or in mine, depending on your perspective) - the so-called terrible twos - I was hoping that this book might have some magic answers. It doesn't. It basically covers the same ground as other parenting books, a combination of, say, Lise Eliot, and the Happiest Toddler on the Block. The suggestions are hard to implement, as acknowledged by the author, when you have been so pushed to the edge by sleeplessness and tantrums so as to have become a toddler yourself.
What I did like about the book were the cartoons and pictures, and the fact that it covers all ages and stages, so I can see myself returning to it. However, the techniques were spread across all ages all the time, so it was harder to focus in on what might be appropriate for me and my child at this very moment.
Overall, I like the general ideas/principles behind the book, but I'm not sure that it stands out in the field of parenting books based on similar research.
