K.G.
Check out the book, "Toilet Training in Less than a Day." We used it with our son, and although he didn't train in a day, he got the whole concept down, and was trained very easily at 29 months old. We had originally tried at 27 months, and then let it go for two months when he showed no interest. When we tried again at 29 months, he was telling me he had to go the first day.
We just tried with our daughter, who just turned 2, and she isn't physically ready yet, but we're hoping having taught her the basics will make it as easy as it was with our son.
I checked the book out of the library, and found it at Amazon for about $7.
Good luck!
