Query: Step-by-step instructions

When my son was 2, I had to get him potty trained in order to enter preschool at 2-1/2. I tried other books and methods which were very vague. What I loved about this book are its step-by-step instructions that REALLY WORKED! Although it took more than one day, by day three, we were taking day trips and were having NO accidents in the car (though a few at home).I recommended this book to my best friend and sister for their kids. They waited until their children were 3 and had even more success with no accidents at all. There's a lot of prep work and you have to be a shut-in for a couple of days, but it's well worth it. Fewer headaches and it's done quickly. No prolonging the toilet-training process over many weeks or even months!!I LOVE it!
