With my first daugther, a few weeks after her second birthday I informed her that she was not allowed to wear daipers anymore and we threw them all away. That worked beautifully. She was potty trained around the clock within 5 five days. I really did not understand why my sister, whose daugther was a year older than my daugther, could not get her child potty trained. I was convinced I had the answer to potty training.
Then, my second child came along. When she turned two I tried the same thing and it was an absolute disaster. She, like your daugther, is extremely stubborn. She knew what to do but wasn't about to do until SHE was ready. I finally just left her alone and all of a sudden she just did it. You would think that that experience would have taught me a lesson but it didn't. When my son turned two and a half, I gave him some extra time because he was a boy,I did the same thing I did with the girls. I was convinced that because he was more easy going like my oldest, he would simply start using the potty when I told him it was time. Unfortunately, it did not work. I then went to reward charts, M&M's and finally out-and-out bribes. I really wanted him to start preschool this fall. When mid-July hit and he was still wetting his pants, I gave up and left hime alone. By the second week of August, he informed me he was ready to use the potty and has been dry, other an accident here and there, since. He will be three tomorrow.
Before my second and third children, I didn't believe in the theory that they "have to be ready" but now I am. She is still young. Does she play with children her age? Are they potty trained? My middle child became motivated when her best friend start using the potty. I don't know if this was helpful but I thought I'd share my experience. Good luck.
