Well it seems she playing into what she knows. Now she knows when she has to poop. She seems like she doesn't like to be dirty because she's reacting like you would. (she knows what you expect) She's pretty much saying "I have to go poop i know it's dirty and i don't want to do it. " She's trying to find a solution to her prob. of not liking to go but doesn't like it in her diaper either because she have told her that isn't right. So what i would do in your case is start over reacting to the how GREAT it is she goes in the potty or the fact she CAN go in the potty. Going in her diaper is dirty, going in the potty is VERY CLEAN. This is great. You are giving her the solution to her problem.
