Ask what she means.

"What do you mean?" You ask. "Do you know what's going on?"

"You're going to be mad." She says.

"What have you done?" You're already getting mad. "Why are we dressed like this?"

"It's a kind of magic." She explains. "I've changed reality."

"You've changed reality?" You roll your eyes. "How would you do that?"

"I found this weird store yesterday, after you told me about your new job." She explains. "The guy in there somehow knew I was upset about you moving away. He said he had a way for me to keep you here."

"And what's that?" You play along despite not believing a word of this.

"It was a baby's rattle in the shape of a {if Girl=true}pink {endif}magic wand." She says. "He explained that if I shook it while concentrating on someone I could change reality around them so that they lived like a baby{if Girl=true} girl{endif}."

"So you used it on me?" You ask.

{if Kate=true}"And Kate. I wanted you two to still be able to be together."{else}"Yes."{endif} she says. "I must have been thinking about how you wanted me to come with you when I shook the rattle."

"So we look like babies to everyone else?" You ask.

"No." She says. "They still see what we really look like. They just think we are babies and nothing we can do will convince them we aren't."

"And where do the over-sized diapers come from?" You ask, still looking for a slip up to show she doesn't really believe what she's telling you.

The magic makes it so that anything we need is always available in our size right next to the normal baby things." She explains. "Even things like cots." She indicates the bars all around the two of you."

It hadn't registered until now but not you realise you are in a cot. You look at the room past the bars. It's your room but at the same time it's not. It's the same size and the door, wardrobe and window are in the same places. Even the view from the window is familiar. However, everything else is different. this giant cot is where your bed was and your desk has been replaced by a similarly large changing table. A variety of baby toys are stacked neatly where you once had a bookcase.

"You've gone to a lot of effort for this prank." You say.

"It's not a prank." She insists. "If you don't believe me call for Mom."
