Celestia: Do you have anything to say to me yet missy?

Nightmare Moon: “I don’t…”

Celestia: “Funny, cause I think a curtain somepony might be approaching the one hour mark on her out time. Your snack is gonna get dry soon.”

Nightmare Moon: “I don’t care for cookies anyway.”

Celestia: “You know why you’re in diapers don’t you sister? Stale cookies are bad for a little filly’s tummy!”

Nightmare Moon: “Does thou look amused?”

Celestia: “Allright stinky pants, you can stay in the crib if that’s what you want!” Lifts Luna up with her magic

Nightmare Moon: Pouts

Celestia: “And don’t think about trying to escape! You’ve already been regressed once and it’s from a filly to a foal from here on out!”
