So we have been doing potty training, on and off, since the middle of Summer. And then I realized Chase was choosing to use her diaper over the potty - she actually TOLD me she wanted to use her diaper instead of the potty. That's when I knew I needed back-up.
So I told her that the make-believe diaper fairy was coming. And that if she put her diapers outside her bedroom, she would get presents and the fairy would re-distribute the old diapers to other children that needed them.
Interestingly, on diaper-free Day 1, she had 5 accidents. On day 2, she had 1 accident. Today, day 3, she had no accidents and she really seems to be getting the hang of it. I guess time will tell.
