While being designed specifically for girls on the Autism Spectrum, and girls with other Developmental Delays-- No More Diaper can certainly also be used for all girls who are learning to go "potty" on the toilet. It was inspired by the author"s oldest two daughters who both have Autism. The author needed help and was unable to find it in available books. She knew her children and many others needed visuals and step by step instructions--so, thus was born No More Diaper. "I know you ll enjoy this book with your daughter, as much as I have with my daughters" says author Esther Smith. The author says--while using this book was no overnight success--it has helped immensely and has been the only thing, so far that has helped.
