This is a Positive Discipline book.
First off, I love the concept in the title of this book. Children learn from us, they copy our behaviors and our attitude. If we yell at them, they will learn to yell. I love that the author addresses the parents, and the parents' behavior, as a way to get better behavior out of our kids.
I enjoy how he explains one example after another where, on the surface it may seem like your child is intentionally being disobedient or not listening or misbehaving - but then he explains developmentally why they are doing that behavior, and why it makes sense. It helps see into the intent of the child instead of looking at their behavior through adult eyes. So that's great. Just because the kid isn't misbehaving, that doesn't mean you let them do whatever they want with no teaching, and this author is good with ideas of how to teach your child, clear from when they are 1 year old and whining or crying instead of making an effort to communicate. His techniques fit into my philosophy of respectful parenting.
The book has a big chapter on "Time Outs" - but not for children under the age of 3. He also believes that they're a last resort, not a first reaction, and the way he talks about time-outs sure isn't the way I've seen other parents do them (it's a much nicer way, although we don't do timeouts, I don't think I'd have a problem with his way) He also says if you're not a fan of timeouts, don't do them.
There are a few other minor things I do not like in the book. Using "big boy/big girl" as a way of manipulating your child to behave the way you want. I disliked all of the TV references sprinkled throughout the book. For example, TV was listed as an option of after-school activities to help your kid calm and destress from their day. Here I just think the author must not know how overstimulating TV is for kids. His other options on the list I thought were all great, but... TV!? I didn't count, but it was mentioned at least 4 times throughout the book, as a normal activity. I didn't like what the author had to say about positive reinforcement or using food as rewards, but those were tiny bits of the book.
There was one example, he talks about how a preschool girl goes out to eat at a restaurant with her family. She's on great behavior through the entire meal, but barely touches her food. Her parents remind her that if she doesn't eat her dinner, she can't have dessert (I disagree with that concept, but whatever). Then her parents get ice cream cones and eat them in front of her. Seriously!? I totally understand following through with your warning - don't tell your kid they can't have something and then cave. But what parents would really eat ice cream in front of their preschooler??? Couldn't they have just, you know, decided not to have dessert themselves until after she was in bed that night or something?
Personally, I prefer Gentle Discipline over Positive Discipline, but this book does have many GD techniques within it, and overall I'd recommend it. I'd especially recommend it to parents who are yelling at their kids, spanking their kids, or otherwise frequently doling out punishments when you'd rather not. There's a more effective way to be a parent and have well-behaved children, and this book will help.
If you're already into gentle discipline, this book may not have much new material for you.
