http://www.pottytrainingconcepts.com/CTGY/Potty-Training-In-One-Day.htmlThe concept of Potty Training using potty dolls was introduced in 1974 by two psychologists named Nathan H. Azrin and Richard M. Foxx in their book "Toilet Training in Less Than a Day".
They were researching how to potty train children with special needs (autistic, down syndrome and mentally retarded) . Read more about the research and the book in this article with the same title as their book - "Toilet Training in Less Than a Day".
Dr Phil has done two shows on Potty Training in One Day. His first show aired on November 8th, 2002 and the second show in prime time on September 22nd, 2004.
Dr. Phil's first show was part of a series called "How to get your child to..." where he covered topics such as sleep through the night, eat what you eat and of course potty training.
On this show, he showed 3 mothers how to potty their children using a potty doll and how to do it in one day. (This is the show that inspired me to invent the potty training dolls - Potty Scotty and Potty Patty).
On this show he covered topics such as parenting mistakes, raising your child's IQ, spoiling your child rotten and of course he had many celebrities like Patricia Heaton from Everybody Loves Raymond, Amy Brennerman from Judging Amy talking about the challenges of being a working parent.
