I bought it, I read it, people laughed when I told them about it. I stressed about it, researched it, studied it, and you know what?? It was a succes...it took me 13 hours, which means 2 days, one day of 7 hours and 1 day of 6 hours and it works. I don't know how, but I followed the steps and HE got it. He figured it out on his own and he was only 23 months old. Now he's 2 years and 4 months old and he wipes his own bottom and does a fantastic job at it. The important part is to follow all the steps. I duplicated the forms in the book, made my own on my computer, posted them on my kitchen cupboards and followed along the routine and it all worked out. The first day I was too stressed out, but when I put him to bed that night I told him we were both going to relax the next day and get through it, and it worked like a charm. If you're concerned about the chips, pop and candy mentioned in the book, then replace the treats. This book was written a long time ago. They mention those as treats, but my little guys idea of a treat was strawberries, grape, and apple juice, oh yes I did use Cheezies, because those were a definite treat for him. I've recommended it to many other mom's and they're getting ready to do it as well.
