I mentioned that Pete had started to like the Stevie Wonder song "Supersitition." For a while, we could convince him to go along with a diaper change by conflating the changing table experience with listening to Superstition, which was cued up on the stereo in the nursery. Noting the need for a new diaper, we would say, "Hey, Pete! Do you want to go listen to Stevie Wonder?"
Perhaps you see where this is going. "Listening to Stevie Wonder" is now an established euphemism for the process that leads babies to diaper changes, as in, "I just have to listen to Stevie Wonder, and then I'll be ready to go."
Sadly, due to the diaper rash caused by a stomach bug, listening to Stevie Wonder is now horribly painful for Pete. It's hard to watch, like the kidney stone episode of Deadwood.
