"You want to what?" Kurt screeched. It was Saturday night and he and Rachel were having a sleep over at Mercedes' house and Rachel had just shared a shocking secret with them.

"I want to know what it's like to be a baby." Rachel repeated, looking him straight in the eye.

"And how do you plan on doing that?" Mercedes asked.

"You can buy all sorts of things for babies that are adult sized." Rachel clarified

"Who's going to look after you?" Kurt asked, slowly coming to accept that nothing was going to change Rachel's mind.

"Well, that's where you guys come in. I was wondering if you would mind terribly if you looked after me? It would only be for a few weeks, I will change back after about a month." Rachel told them eagerly. They both stared at her with their mouths hanging open.

"You've got to be kidding!" Mercedes cried.

"We're sixteen!" Kurt said at the same time

"I know. But it's a risk I'm willing to take."

"Er…Rachel, you know you could just be an adult baby without all the stuff." Kurt suggested.

"I would still need someone to look after me." Rachel pouted at her two best friends.

"I'm sorry Rach, I just don't see this working." Mercedes said.

"Kurt? What about you?" Rachel rounded on her other friend. He shook his head. Rachel sighed.

"Fine." Rachel got up off the bed and quickly changed out of her pyjamas and silently left the room leaving behind two shocked teenagers.

Rachel drove to a house she had only visited once when she was very little. Taking a deep breath, she knocked on the front door and waited for her secret blond girlfriend to answer. She didn't have to wait long before the girl appeared, grinning.

"I take it they didn't agree?" she asked smugly. Rachel shook her head.

"Don't worry, baby. I'll do it for you. The nursery upstairs is all ready for you." the blonde dragged Rachel upstairs and into the nursery. There were little gold stars over the walls and every surface.

"Thanks for doing this. I don't know what made me want to do this but I've been wanting to do it for a while. Thank god I live by myself anyway so no-one will miss me." Rachel babbled as she lay back on the changing mat and shimmied off her underpants, allowing her girlfriend to powder her and enclose her most private areas in a cute little diaper with a cartoon character on the front. Rachel was silenced by a pacifier and she grinned around it as she knew she had her mummy.

"I will be looking after you while you go through this, don't worry. But you have to listen to everything I say, okay?" the blonde girl said as she finished changing Rachel. Rachel nodded and sighed contentedly.
