My mother used this 1-2-3 counting when I was a child and perfectly worked for us. So I also use it with my children, but I didn´t know, until I read this book, how and why it worked. The techniques are well explained and easy to practice. What I liked the most is the “no talk, no emotion” posture. It´s good not only to stop bad behavior but also to stimulate your children to cooperate in the daily routine. It´s worth reading.
