Our DD is almost three and bright as a button. She's appeared to have "cracked" potty training a number of times and then she'll regress, having days from hell with six or more accidents, looking us straight in the eye, smirking as she's doing it in her pants. We're running out of patience (and clothes)! We've tried frequent reminders, reward charts, ignoring and removal of screen time.
And nothing's working... Suggestions????
