I want to introduce the potty chair to my 15 month old-no pressure to succeed so soon, but get him used to it. How can I do this? I bought a chair and have it in the bathroom and even put him on it, which he quickly got up from turned to face it and peed on the chair-not in it. It was really funny.

So, how can I get him acclimated to the presence of the chair? I want to start training around 20 months. I know it's possible to train children that young, but I'm a realist also and know that it may not happen the way I expect. I have no persistent time-frame.

Should I let him be diaper free for periods of time? How do I teach about wet and dry diapers??
