After refusing to use the bathroom at my mom's house (claiming he didn't need to go despite his little dance) we began the drive home. Asa started reciting what he would do, "Go home, drive car, use potty."
He wasn't able to make the drive.
I put Asa on the potty while I cleaned up only to come back and find him enjoying splashing his feet in the potty.
So I moved him into the tub only to come back and find him wearing a soaking hat.
