123 Magic is a one size fits all, quick fix approach that does NOT address the root cause of why children misbehave. It may bring fast results as long as strong temperament is not an issue, or if the ONLY problem is that the parent has been too lenient and pleasing in the past. There is no help for parents trying to prioritise which behaviours to focus on when a child is truly out of control. Without a clear strategy to initiate change, a partent can easily be overwhelmed by a childs strong and fiercly oppositional reaction to even minor changes. For this I would highly recommend the book "Ain't Misbehavin" by William P Garvey, "Setting Limits: How to Raise Rresponsible Independent Children by Providing CLEAR Boundaries" by Robert J MacKenzie or "Try and Make Me" by Ray Levy and Bill O'Hanlon. For an in-depth book that explores both the parent and childs role in power struggles, I would recommend "The Manipulative Child: How to Regain Control and Raise Resilient, Rresourceful, and Independent Kids" by Swihart and Cotter. I do however agree with the books suggestion of no emotion or anger during discipline on the part of the parent. But even this is contradicted by the author who suggests that a smack on the butt for a child fighting a time out as being acceptable. Also I found the books tone sort of negative and demeaning towards children at times, making comparisons to "wild animals" that need training. There is some good advice on interrupting behaviors but overall too punitive for my liking.
