You close your eyes, take a breath and say...
~Madison now has to wear diapers, and I am going to be her caretaker. The three of you will totally, happily accept this.~ You point over to the other family members at the door.
"Maddy," Amber says, stepping further into the room, "he's trying to clean you up, and let you be more comfortable, okay? So please don't make it hard for him."
"WHAT?!" Madison screams. "DAD!! Tell Amber to get out of here!!"
"Listen to your sister, sweetie." Andrew says, approaching her by the door. "It's okay that you have to wear diapers, we all have special things that we have about us."
"What's going on?? Why are you all BEING like this?" Madison frets, seeing even her mom nodding in solidarity with the others.
"Come on Maddy, it'll be quick!" You chirp, crinkling the diaper and approaching her, taking her hand.
You lay her on the carpet.
"What? I don't understand what we're doing."
"I'm gonna put you in a diaper."
"...I don't understand..." A tear drips down her cheek, and she looks up. "Dad... why is this okay? Why is he allowed to do this?"
"Maddy..." Her dad squats down. "Your mom and I used to change your diapers. Even Amber changed your diaper a few times."
"But I was a baby..."
"Well what made it okay back then, but not okay anymore?"
"...." She bites her lip. ".......who IS this guy??"
"Sweetie, he's a good friend of our family, you know that."
"...I guess..."
"Now lay down at let him put you in a diaper, before your pants soak into your carpet." He pats her on the leg.
She slowly wipes off her tear, and nods.
"Good, thank you for cooperating." Her dad stands up, and the rest of the family weave out of the room.
Madison lays down and you undo her pants and underwear, unfolding the diaper, wrapping it around her and taping all four tapes into place.
"How's it feel?" You ask her, pulling her up.
"...squishy..." She stands up. "I still smell like pee."
"Yeah, I forgot to command your mom to buy wipes and powder and all that stuff." You say, rinsing her soiled clothes in the bathtub and draping them over the shower rung.
"You 'command' my mom?"
"Oh uh--" ~I said 'ask' instead of 'command'~
Madison pokes at her diaper. She opens her second drawer and pulls out a pair of shorts.
"You probably shouldn't wear pants right now; you've still got pee on your legs."
"Well whose fault is *that* for not asking my mom to buy me wipes?" She looks back at you. "I'll get a rag." She takes her shorts in hand and goes to her sink.
You wet the rag for her, and reach down to her legs.
"Hey, I'll do it!" She tries to grab the rag out of your hand, squishing her legs together and dodging your swipes.
You think.
"Okay, you can do it just this once." You give it to her. "I'm going to have your mom buy you some wipes, and I'll be taking care of it after this."
"Why are you treating me like a baby?" She asks perturbed, cleaning her leg. "I peed my pants just one time, and now all of a sudden I have to wear diapers. I'm going to show all of you people that you're being dumb when I use the toilet just fine with no accidents every time after this."
Next, you decide...
