Re: wont poop on potty
My ds did this, but instead of putting underwear on him, I let him run around bottomless for a while. When the real poo came, all he had to do was make a run for it - no fussing with the underwear.
Also, the underwear can feel like a diaper and her muscle memory might revert. Pooping in the underwear feels more natural to her right now.
Yeah, so ditch the underwear.
