I just finished successfully potty training my third child, who is 27 months old. Two year ago when I had to potty train my twins I knew that I needed some rock solid advice so I did what I always do and went searching online to find some answers.
I decided to go with Lora Jensen's 3 Day Potty Training program. I bought her online book for around $20 (not sure what the price is today) and it was the best decision I could have made. Her methods are simple, very natural and very logical, which is right up my alley. Plus, if you need it, you get online support for any snags you run into. I personally didn't need the support hotline, but it was nice to know it was there.
I trained my boy girl twins at 28 months of age, at the same time, in 3 days. It worked. And then I trained my other littl boy two weekends ago and it worked like a charm again. Actually, he had his "ah ha" moment the morning of the first day and the next two days were just for good measure.
I highly recommend this lady's method and can honestly say that it worked for me on three kids. Three cheers for NO MORE DIAPERS!
