I think I found a way to potty train that works for me. I wait until the child is well aware (and I am too that they know) of the sensations of going potty.
Then I say to them, "OK, your a big girl now", and put them in their "big" girl panties. Give them their favorite drink (In Bean's case Capri Suns) and let them have as *much* as they want. They will have a couple of accidents, but they will be going all day, and finally learn how to control themselves. It took about a day for Bean to learn. On the second day she had about two accidents. Now she has very few, as long as I am consistent in making sure sits on the potty every two or three hours.
During the training process she got a piece of candy every time she went to the potty. She caught on to the this pretty quick, and would come tell me she needed to go potty so she could get the candy. So it was a very positive experience for her, because she drank juice that she rarely has, and ate tons of candy.
