I wish I could remember and credit the author of this book, something along the lines of Potty Training in Three Days. In essence, the trick is to get the child to take responsibility. So you stay home a few days, and stick to the easily cleaned parts of the home. You put on easy to remove clothing. You give the child fluids, fluids, and more fluids (even 'treats' like juice and soda). Your goal is to have the child get lots of practice. But you don't praise her for 'using the potty'. You talk about 'staying clean and dry', although you can, if necessary, suggest using the potty as a way to do that. Think about it. In a way, you don't care if she never uses the potty- what you care about is that she stay clean without you having to change her diapers. (Of course, you also care that she is healthy and hydrated enough to urinate and excrete, but that's not a problem right now!) If she's clean and dry after two hours, great! Reward her (maybe even with something to drink.) When you see that she isn't, make sure she participates in the cleaning up (ideally she does it all, but I understand that you may need to go behind her a little to keep your home sanitary. When she deals with the mess either way, and the easy way is readily available - she'll use the potty, or even graduate very quickly to the convenience of a flush toilet!
