You guys, I need help.
A little background...we started practicing with the potty over a year ago, and decided to jump into modified "oh crap" potty training. We went a solid 3 weeks in underwear and shorts with virtually no accidents (there was one when he fell asleep in the car).
Last week he went to a new preschool where he was the oldest in the class and possibly the only one potty trained. He went two mornings. Then last weekend we went out of town. We kept up our routine other than that. Last week he started becoming a bit resistant to going to the potty, but still would. By the weekend it was a battle, and I had to reintroduce rewards. By the end of the weekend, even with the rewards he was still having 6-10 accidents a day. This has continued all week. It literally does not matter how often I take him to the potty. If he is wearing underwear, he pees in it every time. Today we went to target and he peed before we left, then in the car (it's a 7 minute drive), peed in the potty when we got there, and then by the time we got to the checkout he had completely soaked through his gerber underwear, shorts, and the stroller seat.
What. Is. Happening?!? And what do I do about it?!? We went back to naked from the waist down and that seems to help at home, but the second the underwear back on it's like he completely forgets.
I knew it was too good to be true... Has anyone navigated this before? Help!!
