Mememe, I know it might be hard, but STOP giving into her demands for a diaper and if she has accidents in her underwear, so be it. Each time you give her a diaper you are reinforcing to her that this behavior is acceptable.
When my son was two and half, he articulated very well one day that "Mommy, last diaper, got to buy more." If he could say all that, he could tell me it was potty time. He hated it, but we got through it and so will you.
