This book is part of the "Everything" series of books, so you would expect it to have a little bit of "everything" about potty training in it. Unfortunately, I had to read the entire book to find out that the author's clear bias towards infant potty training continues into the sections on toddler training. I was hoping for a less opinionated book, one with more general information.

The author clearly believes you should train an infant and not use diapers. But then there isn't a clear plan for training a baby. This is kind of a mix of lots of ideas without a committment to one specific plan. Kind of confusing, not too helpful.

I think this was a good first book for parents about to tackle potty training. While as some have posted the author does clearly think infant training is best, other methods are also clearly presented and outlined. Use this book as a starting point. It outlines a few major methods. From this you should be able to decide which method you want to use and then focus your next book purchases.

I found this book to be infinitely helpful in toilet training my daughter. Because the author presents four different methods of potty training, she isn't obligated to advocate her method and dismiss competing methods as "wrong". Acknowledging that there are many correct ways to toilet-train a child is something that few authors have the latitude or courage to admit. This book also presents practical, non-judgemental advice regarding which method may work best in different family situations. After reading about all the approaches, I was able to fashion an approach that was consistent with my parenting style and worked well with my daugher's personality.

I had to make a comment about those reviewers that gave this book a low rating. Dr. Sonna's approach on potty training may seem different to many, but it is very, very effective. Her so called "bias" is to train kids in a different way than what we are accustomed here in the USA. If you are buying this book it's because you are needing help in this area. Maybe her advice is the advice you don't want to hear, because you've been approaching potty training with no results, and feel you couldn't possibly be doing it wrong. Some of the people who negativiley criticize this book because it's teaching a different approach to toilet train probably would criticize their doctor for perscribing a pill that cures an illness that is causing pain, when all they wanted is a pain killer. If you ever travel abroad you quickly learn that here in the US our kids are toilet trained much later than anywhere else in the world. Her pointers, suggestions, and even, thank God, her humor really help you deal with what is really not a fun and messy issue in child rearing. Throw out your (mis)-conceptions on potty training, open your mind to a different approach, buy this book, and follow the advice. The bottom line is: IT WORKS! And isn't the whole point in buying this book to find a method the works?
