Yes...I did it with my daughter who wans't quite two yet. It worked like a charm in my opinion, but not exactly like the book said it would. There were several wet panties, but she did potty train in a couple days for the most part. I have an expedition, so when we went somewhere I could put the potty chair on the floor. If she told me she needed to go, I would pull over and let her use her potty chair....I live 45 miles from the nearest "city" so going to the city is a LONG time for a child to wait to use a toilet. She NEVER went poo in her pants ever again, but had issues with remembering to go pee while playing outside for a while. I highly recommend this system and lots of candy. The neighbor girl who was three had a harder time, (we trained them together), so we decided to give them a "Potty Party" when they had made it two weeks with out wetting their panties....We took them to Chucky Cheese and had a princess party for the girls. It is all just a starting point and I believe the LOTS of fluids and candy leads them to having several chances to get candy and learn the ropes quickly.
