I got home to find that Colton slept through the night, and lasted all the way until George changed him, without an accident.
** Update, this was a one-time occurrence. The next three nights following he wore the pants while watching Dora (with his backpack) and peed at least once each night. But eventually it will come.
We are using the backpack as a motivator. Big boys get to use backpacks because they don't have to bring diaper bags. He gets it, he's just not ready to take that leap.
