"I know, Titus--you can earn a surprise if your pull-up is still dry in the morning."
"Okay!" he said, eager to earn his surprise.
So, bright and early Titus jumped into my bed and in his cute little voice exclaimed, "Mommy, I changed my pull-up so my pull-up is dry now... can I have my surprise?"
"Oh, sweet boy, let me clarify... if your pull up is dry because you didn't wet during the night, not because you changed it..."
Poor kiddo. It's my fault for not being more specific with my expectations!
