Maybe peer pressure will work in my favor. Overhead at lunchtime:
Maddie: I'm wearing panties today, sissy, what you have on?"
Izzie: I'm wearing a bop (diaper).
Maddie: Oh, you mean a panty-bop (pull-up)?
Izzie: No, a regular bop.
Maddie: Oh, well I am a big girl today.
And then the conversation turned to food.
