I trained my 3 year old boy in less than a day after trying many methods. My goal was to stop having 2 children in diapers (my daughter was 1 yr. at the time...sounds familiar). Answer: "Toilet Training in Less Than a Day", book by Arzan & Fox. Amazon has it. I followed it to a 'T' and it worked. In fact, so well that I trained my daughter at 23 months! But, you must do it exactly like the book advises. Basically, they have you use multiple motivational methods at the same time WHILE making staying in a messy diaper worse than going potty. If there is no discomfort (especialy with todays super absorbant diapers & pull ups), then why should a 3 year old boy be motivated to change? When my son made a 'mistake', I asked him why? Being he was articulate and smart, I know knew he was building up reasons to not change and manipulating me. His answer was "I didn't want to". The training from the book made him "want to". Good Luck!
