An FYI for people looking for a PT book, it's called STRESS-FREE POTTY TRAINING by Sara Au and Peter Stavinoha phD.
I liked the book because they give you a quiz to find your child's temperament and then offers advice on how to potty train based on that temperament. They also have a universe PT method and a relapse chapter. Anyway just wanted to let you know. GL
