My kid is three years old. We did the first three days of the three day bare butt method very successfully - no accidents.

But today is day four so I put her in big girl panties and she’s been forgetting I guess? and starting to pee in them, only to rush to the potty (while still peeing), sitting down on the potty (with them still on because she’s in a rush because she’s actively peeing), and finishing there. Most of the pee gets in the potty but it’s through her panties.

I’ve never read the book (and honestly don’t plan to), so what is supposed to happen on day four of this method? What do I do? Back to bare butt?
