Ask to see Sarah as a baby.

"This is all a bit strange." You say. "Would you let me see you as a baby?"

"Of course." She says, although obviously nervously. "I hate hiding this part of myself from you."

She collects her keys and takes you back into the nursery. "Do you want to choose an outfit for me?"

"Okay." You say, going to the wardrobe. You look through the options, finally selecting a short pink and white chequered dress.

You turn back to Sarah to finding her standing in nothing but her diaper. She smiles at the dress you've chosen.

"That's one of my favourites." She says.

You help her into the dress. It is so short that a little of her diaper peeks out underneath.

"There's a matching diaper cover in that drawer." She points.

You open the drawer revealing many different diaper covers. After a brief search, you find the right one and hold it out for Sarah to step into. As you pull it up her legs and over her diaper you notice "You're wet."

"These diapers can handle a few wettings." Sarah says. "I should be fine until Tanya checks it again."
