N.D.
I just wanted to agree with the mother who said to go ahead and try, but boys seem to take a bit longer. My daughter was two and the three boys were all three years old. I never 'trained' them, any of them. I started with books and movies and everytime I changed a diaper and I would remind them where the potty was, what it was for and just let them know when they are ready they can use it. All my kids just woke on morning and asked me for underwear, no accidents, no struggles, just diapers to toliet in one day. I say let them be the boss and there will be no issues with the toliet learning, no matter what the age is. Good luck.
