2,5/5. The book is really more of a guide made for parents who wants to try relaxation/meditation with their kids. A child alone won't be able to enjoy or use it properly. It propose a couple of exercices, simple enough but decent, that you can try easily at home. It loose a couple of stars, because of guide aspect (that's not bad in itself, but not really what I was looking for) and because it was way too simple in its content to be really good. Maybe for the parent who want to try and have really no idea where to start at all. If not... you can pass on this one.
