My first was 3 when she was finally 'trained'.
Every child is so different.
However, your article is one many moms I know can relate to, so I've passed the link to your site on to them as well. Brazelton says they'll get it when they get it. So, I have no prejudices toward either camp, both seem to have some merit. I think 18 months to 2 years is a good time to start potty training. I observed a friend of mine a few years ago who let her child wait until she was older.
