I've been a believer of this method for years - after seeing it practiced quite naturally overseas - but wasn't sure it would work in our society/culture. Although he had his moments, my son was diaper-free by 26 months. :)
This is how I got my 14-mos. toddler potty trained.
Wow, I wish I knew about this book when I had the baby. At 14.5 months my daughter's behind in her toilet training. Who knew?
