This book is very close to five stars, maybe only because of my preferences of a few things, it's less than amazing. Those things are first, the formatting of the book, which has these infoboxes and things in every chapter that makes me lose focus just so slightly from the main thread. Secondly, that they introduce a model and with it a language, and I just wish they told things plainer. I understand the need for a model, and it is great, but how does one explain these things to other people without having to at least give a quick summary of the whole model? Well, not easily, and neither am I going to remember it all by the model. Anyway, the model does exemplify a lot of issues, and explains them in a quite easy way - maybe a little bit complicated when entering into the sensitivities, but even then I managed to follow so and so. Usually, if you map out your sensitivity, you are mostly caring about that one and the secure one - what to aim for. The same goes with the book spanning a lot of ages, not always relevant to you and your child in the nearest future. A shorter, 100-page book of this, aimed solely at a one-year-old, would be much more helpful.
To the point though, I did learn a lot and get a lot of pointers from the book in understanding how attachment work, and how to work toward a healthy style of parenting. It is much more detailed and makes things close to the science as well as real situations, and that is very valuable. It is not "just one person" who has an idea about how to parent the best and wants to share it with his/her experience without touching the scientific material on the broader issues. I would recommend this book as a good book on parenting, one of the better so far.
