DS was 95% potty trained for several weeks. We still use pull-ups overnight, but he rarely had accidents anymore. Then I went out of town last week for work and he started having 2-3 "accidents" / day at preschool. They told DH when he dropped him off today that he does it when he doesn't get his way. Gah. I'm not sure how to even address this. He had a few accidents with DH while I was gone too, but DH didn't say it was intentional. Any thoughts on how to address this? Incentives don't seem to work.
