Did you give a reward the first time or two to positively encourage it? Or did you just wait til they filled a chart/mastered it?
We started casually training and yesterday I figured what the heck. Threw some underwear on her. She had one pee accident and I got her to the potty in time for a #2 (she was about to go in her undies). I made a huge deal bc she was nervous so I was thinking of taking her to pick a reward today - hoping it'll encourage her to keep trying!
