V.C.
I'd do a search (on yahoo, google, or whatever) for 'potty train video' or something like that. I'd also go to ebay.com and Amazon.com and type in the same words (and similar but different combinations to have the best potential for finding what I'm after).
If you can get them trained when THEY'RE ready, it's a lot easier than just waiting and letting it happen and it gives the child more of a sense of accomplishment, I believe. (I have 4 adult children and 3 grands. My 4 were all fully trained by age 2, just because I love training! : )
