Hi! My little guy is one so we're not there yet but this has been on my radar lately as my step-sis just potty trained her little girl age 22 months - her 4th child and potty trained much earlier than her other three (2 girls and a boy). She read the e-book about potty training in 3 days (I think you purchase online, here's the website http://www.3daypottytraining.com/) The biggest thing is you need to commit to staying home for 3 days and basically follow your child around...and use the language the book suggests (which may be different than other approaches but tells you what to say and what NOT to say). Totally has worked for them! She's dry at night and naps. A few accidents of course...but usually when she signs "toilet" and people aren't paying attention! According to the book 22 months is a good age. She just did it in the last month - she'll be 2 on Sept 10.
