She doesn't take the diaper

As reasonable as that was, Christy still wasn't having it and she shook her head vehemently. "No! I'm not wearing a diaper, Stacy! Absolutely not!"

A bit of a sigh escaped Stacy now, knowing just how difficult this was going to be. She took a moment to think before finally speaking up once again. "Alright, how about this: We'll make a bet. I'll let you stay in those pull-ups and you won't have to wear diapers, but we add your name to the potty chart. You'll have until one of our current potty trainees graduates to big kid underwear. If you can go 7 days without a messy accident during that time, I won't bring the diapers up again." A smile crossed Christy's face after that. She'd had a bit of bad luck lately with these accidents, but 7 days was certainly possible.

Stacy quickly put a hand up to stop that smile, though, as she wasn't finished. "If you can't manage that, though, and one of our trainees gets fully potty trained before you can manage to stop pooping your pants? Not only do you have to wear diapers, you have to let me take care of you like I would any other baby that gets dropped off here until we can get your potty training back to where it should be." She stated that rather authoritatively, making it clear that she wasn't joking around with this suggestion. Christy didn't seem thrilled with it, but Stacy quickly added on: "If you're not okay with that, then you wear diapers now. Those are your options."

At this point, she didn't see much of an option. There was no way she was going to willingly wear diapers, so the bet was the only option she could consider. She just hoped she could make it to bathroom more often than she had in the past week. "I'll take the bet."

That response got a smile out of Stacy as she nodded her head. "Alright, that's a start then. Let's go get your name added to the potty chart." With that, she led Christy back out to the playroom and over to the potty chart. She handed the marker over to Christy and pointed to an empty row on the chart. "Just put your name there." Christy blushed a bit as realized most of the kids were watching again, some of them giggling, but nonetheless she did as she was told and wrote her name on the row.

Stacy smiled again, putting the marker back into its usual position. "Okay, consider this the start of the bet. I'll be keeping track of any accidents you have at home too, so just try to make it bathroom alright?" She patted Christy on the arm reassuringly, seeming to be legitimately concerned with getting her back to normal. Christy, though, was nervous. If she couldn't do this, she'd not only be in diapers, she'd be treated like a baby as well. That would be beyond humiliating... but maybe that was just the motivation she needed to keep her pants clean.
