We started to do the exercises with my 7 year old son there is little. This is a child enough speed and the results are quite impressive! Sometimes itself, he poses, close your eyes and calm myself by breathing! This is only a beginning but it is promising. For the record: it opened the brow no longer and, when he did sew, I managed to calm him by doing the "little frog" (speak softly , put his hand on his stomach, feeling her breath ...). I'm halfway through the book and I bcp draws lessons for myself also. Even my 2 year old daughter calls to listen to "the cd frog" at night in bed In short, I highly recommend.
