“Nice job, Sam,” you said, Sam sighing in relief.

“I think she was trying to hex me before I put her down,” said Sam, shaking his head. You hummed, glancing around and pursing your lips. “Where’s Dean?”

“We split up. I thought he came back to you,” you said.

“I thought he was with you,” said Sam. You both took off in opposite directions, combing through different rooms of the house. You were in the kitchen when you heard a baby start to cry somewhere. You opened a door and saw it go down to a basement. You had your gun out, following the sound as it got louder, finding an infant shouting it’s head off in the middle of the room.

“S’okay, baby,” you said, shoving your gun away and picking him up off the cold floor. “You’re alright. The witch is gone and...”

You noticed a lump of clothes nearby, Dean’s navy jacket and his gun in the pile. You stared at the six month old in front of you, wet green eyes staring at you.

“No, baby. No, you aren’t...” you said, the baby scrunching up his face before he was crying again. “Dean?”

He stilled for a moment, recognizing his name but he started crying again and burrowed himself into your jacket collar.

“Okay. It’s okay. We’ll fix it Dean. Stop crying baby. We’ll fix it.”

“Sam,” you said, sitting in the backseat of Baby with Dean an hour later, Sam trying to install a baby seat in the back. “Sam! Hurry up!”

“What?” said Sam, glaring at you, Dean shouting even louder. “Dean! Stop crying!”

“Don’t shout at him, he’s a baby,” you said. “Get that damn seat together so he can get some sleep.”

“He’s shouting his head off and it’s not exactly helping,” said Sam, fiddling with a strap. You managed to get Dean in a diaper, any attempts at finding an adult stuck in that tiny body not resulting in anything beside Dean recognizing his name. “Put him in some clothes. He’s probably cold.”

“Well hand me the bag with the onesie’s in it then,” you said, Dean yelling some more. “Dean, baby. Please calm down.”

“I got it,” said Sam, clipping something in place. He took Dean from you and got an earful, Sam strapping Dean in as he kicked his legs. “Dude. Relax. Here.”

Sam leaned into the front seat and grabbed a bag, shoving a little blanket over Dean and tucking it in, Dean calming right down and conking out like a light.

“Finally,” said Sam, grabbing the bag and shoving it in the back. “Let’s get home so we can get this figured out.”

“Hi Dean,” you said softly the next morning, Dean grabbing his toes in the makeshift crib you’d made out of a laundry basket. “Good morning.”

He scrunched up his face as you caught the smell, wiping at your nose.

“Okay so you’re really like a baby,” you said, picking him up and setting him on your bed. You got a towel under him and some wipes, gagging when you plucked off the diaper. Dean wasn’t crying so far which was an improvement but he got red in the face when you tried to put a fresh one on. “Dean, you have to wear it.”

He tried to pout and you sat next to him, running a hand over his head.

“Agg!” he said, kicking his feet.

“Are you an adult in there?” you asked. Dean seemed to ignore you, staring up at the ceiling. “Or do you really think you’re a baby?”

“Neither,” said Sam, knocking on the door frame as he came in. “I figured out the spell. He’s a baby in most senses of the word. He likely only remembers us as family and that we’ll take care of him. But he’s not arguing that he doesn’t want to wear a diaper because he’s adult Dean. He just doesn’t want to wear one right now...I think.”

“How long is he going to be like this?” you said, Dean grabbing hold of your finger and sucking on it. Sam swallowed and stared at his feet. “Sam.”

“...Six months,” said Sam.

“Six fucking months!” you said, Dean dropping your hand and starting to cry. “Sam we can’t take care of a baby for six months. We’re damn hunters.”

“We’ll have to figure something out,” said Sam.

“I don’t know how to take care of him though,” you said. “I can change a diaper but I don’t know how to feed him or-”

“We’ll buy some parenting books I guess,” said Sam, staring at Dean. “I have some other news you won’t be happy about.”

“What?” you said.

“Jody called. She needs backup on a hunt,” said Sam.

“One of us has to stay here with him,” you said.

“Can you stay?” said Sam. “I ran out this morning and got more stuff for Dean but...he doesn’t cry as much around you.”

“Fine but if I call you better answer your phone. Better yet, give it to Jody, she was a mom,” you said.

“I know,” said Sam, walking inside, putting a hand on Dean’s head. “Be good for Y/N. We’ll try to figure out how to make this as painless as possible.”

By the time you got Dean in a diaper and a onesie, Sam had already headed out. You carried Dean on your hip to the kitchen, finding the jars of baby food and instant formula Sam had bought, Dean giggling as you sat him in a high chair at the counter.

“Well you sound like you’re in a better mood,” you said with a smile, picking up the different jars, finding some sweet potatoes and swirling it up before you set it in front of Dean. You turned around and grabbed a frozen breakfast sandwich from the freezer, tossing it in the microwave.

“Afba agah uf,” said Dean. You turned around, Dean staring at the jar and then you.

“I’m so sorry, you can’t feed yourself,” you said, shaking your head as your grabbed the little spoon and held it to his mouth. “Go ahead, Dean.”

Dean shook his head, pointing at the sandwich you were making.

“No, that’s adult food Dean. You can’t have that,” you said. Dean blinked at you slowly and you swore you saw an eye roll in there. “Dean...are you really a baby?”

He shook his head again, your eyes wide.

“Okay. After breakfast, I’m going to look into that spell Sam found some more. Maybe he missed something,” you said. Dean stared at you, blinking a few times.

Then he spit up all over himself.

“Did you just throw up?” you said, Dean shaking his head again. “Do you have any idea what I’m saying?”

Dean shook his head, patting his hand on his tray.

“Oh course not. Well...might as well feed you like this in case you make another mess.”

“Dude,” you said, Dean giggling on the floor of the bathroom. “You got potato in my hair. I don’t even…”

Dean laughed as he looked up at you, shirt covered in baby food.

“I’m glad you find this hilarious,” you said, peeling off your shirt. You grabbed the little tub meant for washing babies one and under and filled it with warm water. Dean wasn’t sure what to make of it when you sat him in it but he started splashing and he had a big smile on his face.

You used way too much soap, accidentally squirting an adult size amount in your hand but Dean didn’t mind that you had to dump out his soapy water for fresh. When you finished with him, you wrapped him up in a big towel, Dean leaning back in the thing and practically falling asleep on the bathroom floor. You kept an eye on him as you took a quick shower, Dean still passed out once you took care of yourself.

“I really hope this doesn’t take six months.”

Dean’s POV

Pretty much the only reason I wasn’t shouting was because it freaked Y/N out. I’d tried earlier in the day to make her understand that I was a full fledged adult trapped in an infants body and she’d almost caught on but she misunderstood. Throwing up was inevitable with how awful that baby food crap tasted and now we were back to square one.

I didn’t want to act like a baby. I didn’t feel like a baby. But stuff just happened on its own. One minute I’m sitting there, the next I’m wrapped up in a towel in the bathroom with no idea what happened in between.

Y/N was drying herself off after her shower, giving me cautious glances every few seconds while I sat there. Fuck, this was awful.

“What’s with the grumpy face?” she asked, kneeling down next to me. “Do you have to go potty? Do you want your diaper on again?”

Diaper? I’d worn a diaper already? Oh hell no. I was not dealing with that for a day let alone six months.

“Okay, okay,” she said, shushing me and picking me up. I tried to squirm but she sighed and started to walk out of the bathroom and to our room. She threw her towel down on the bed and put me on top, moving around the room before she pulled out a baby shirt. It wasn’t a onesie at least but I would have preferred something with less fire trucks.

She set it it down next to me, cocking her head before she ripped off the tag and undid the bottom clasps, a sigh out of me making her smile.

“Well they didn’t have any black or flannel so we had to settle for the trucks. Unless you wanted kittens and puppies,” she said with a smile. I shook my head, Y/N, laughing. “I know, you want some clothes on. One second little dude.”

She turned around again, dropping something on the other side of the bed I couldn’t see.

Next thing I knew I was being picked up by the legs and when I sat back down, there was something soft there.

“I am not wearing one of those!” I shouted, the words translating to some sort of very loud and high pitched shriek. Y/N blinked a few times and rubbed her ears. I yelled at her again that at least I had control over that function thank God. At least I was pretty sure I did.

“Do you think this is fun for me?” she said, hands on her hips. “Please stop screaming at me. I have to do this.”

She sounded so...off. So already beaten down. I closed my eyes and relented. Maybe after a little while she’d figure out I didn’t need it and we’d figure out some kind of bathroom signal.

God this was going to suck.

Eight Hours Later

“Dean, you haven’t gone to the bathroom all day,” she said, cocking her head at me after dinner, kneeling next to the crib she was forcing me to sleep in. “Are you sick?”

I grumbled at her, trying to say I really had to take a leak and she hadn’t gotten a single message that I was this close to losing it.

“Do you have a fever?” she asked, putting her hand on my forehead. “Sam bought one of those baby thermometers I think.”

“I need to take a piss! That’s what’s wrong!” I said, glaring at her as she stood up.

“Again, screaming does not help,” she said, looking around the room. “Just...stay right there. I’m gonna go see if it was the food I gave you.”

She walked out of the room and I about lost it. I couldn’t get out of this damn thing without help and I was not going to…

“You’re fucking kidding me,” I said, glaring at my lap. “Stupid infant body and I only went because my body forced it and Y/N! Get me out of this thing!”

Y/N came rushing back in at my screams, frowning when she saw how mad I was.

“Oh, you went!” she said. “Maybe you were just shy.”

“Shy my ass!” I shouted, pointing at my lap, instead whacking myself in the leg.

“You’re a very angry baby,” she said, picking me up and moving me over to the changing table she set up. I was glad to be out of the wet one but I most certainly was not going back in one.

I kicked when she tried to move me again, hitting her in the face.

“Ow. Dean,” she said, holding her hand over her nose, pulling it away and a little trickle of blood coming out. She wiped it away with a tissue but more came out.

And for some reason I had to start sniffling. Of fucking course. Did I feel bad? Yes. But it was not a cry worthy occasion and now she was picking me up and telling me it was okay.

“Calm down. It was an accident,” she said, rubbing up and down my back. “I still love you, Dean.”

I leaned back as best I could to look at her, Y/N smiling at me.

“I’m gonna take care of you,” she said. “Just like I know you’d take care of me if I got stuck as a baby.”

“Y/N,” I groaned.

“Okay, okay. I know the diaper pisses you off. How about we make a deal? Daytime, no diaper. I’ll take you every couple of hours to the bathroom. But if we have to go out or at night, you have to wear it, just because you might have to go and I can’t get you to one in time,” she said. “First accident though and it goes on all the time. Agree?”

I nodded, that plan sounding much better.

“I wonder how much of you is an adult in there…” she said. “You can hold it I’m guessing...maybe that’s why you hated your baby food.”

I made a face, Y/N laughing at me.

“Okay. As soon as your teeth come in, you can have some fruit and other stuff,” she said.

I frowned, rubbing my hand up to my mouth, wincing when I realized she had a point.

“Don’t worry babe. Your teeth will start to come in soon I’m sure.”

“Sup Dean?” said Sam, smiling at me when he finally came home. I wanted to yell at him to go give Y/N a break but I hadn’t quite figured out how to spit out the pacifier in my mouth yet.

“Oh, let him watch his cartoons. He’s starting to teeth and that pacifier is his new best friend,” she said.

I narrowed my eyes at her, Y/N giving it right back.

“Is that a potty face?” you asked. I shook my head, Sam wearing a big smile. “Don’t get your hopes up. Being able to hold it and an affinity for pie flavored foods are the only adult things I’ve been able to concretely confirm.”

“It’s only been a week,” said Sam, sitting down next to me. I rolled my eyes, trying to shift away but he pulled me into his lap. “You hanging in there?”

“I hate this. I hate you. I hate everything,” I mumbled under the pacifier, Sam chuckling as he bounced me on his knee.

“He doesn’t like that,” said Y/N, Sam pulling me off his knee to lay back in lap instead. “So how was the hunt?”

“A pain. I’m glad to be back,” said Sam, stretching back on the floor.

“Uh, be careful with him,” said Y/N.

“I’m just taking a quick nap,” said Sam.

“She’s worried about you crushing me, doofus,” I mumbled, Sam sighing as he sat up with me. He picked me off the ground, way higher than Y/N did and I instantly clung to him. The pacifier fell out of my mouth when my jaw dropped, something I’d have to try to remember, and Y/N was instantly over.

“Give him here,” she said, Sam handing me off, Y/N bending down to grab the pacifier and give it back to me. “He got scared. New stuff you have to go slow.”

“He knows I wouldn’t hurt him,” said Sam.

“He knows but...like he goes full blown baby sometimes and you have to slow down. Most of the time he’s just grumpy and wants to watch TV,” she said. “There’s a learning curve to him.”

“Sorry,” said Sam. I sighed when Y/N handed me back but then I sort of liked it, getting to be tall again. “So...what do you do for fun, Dean?”

“Seriously? Jackass,” I mumbled, Sam tickling my stomach.

“That’s a cute little sound,” said Sam, cocking his head. “You smell funny.”

“He needs a bath,” you said, sitting on the couch. “Would you mind giving him one?”

“No!” I shouted, shaking my head, spitting out the pacifier again.

“Uh, does he not like baths?” asked Sam.

“No, it’s one of the few things he likes actually,” you said. “Do you want me to show Sam first?”

I sighed but nodded. Y/N needed the break and it wasn’t like I hadn’t done all this crap for Sam when he was little.

Ten minutes later I was in the tub, surprised at how gentle Sam was.

“Does he sleep through the night?” asked Sam, wiping a cloth down over my hair.

“He does. I don’t,” you said.

Oh boy. This again.

“Trying to research still?” asked Sam.

“Yeah. I’m paranoid something’s going to happen to him all the time and it’s my fault he’s stuck like this. I shouldn’t have let him go off by himself,” you said.

“Stop being stupid. I’m a grown man, or at least was. We did that hunt exactly how we were supposed to. By the way, I’m fine. I’ve started to figure out his crawling thing so don’t worry about me,” I said.

“What the blabbering little guy just said,” said Sam.

“You understood me?” I said, Sam seeming to ignore the comment. “Oh. You said blabbering. Don’t mind me. I’ll just sit here and make squeaking noises for your entertainment.”

“Someone is talkative today,” said Y/N, a relieved little smile on her face. “I’m happy Sam’s home too. But we should get you out before you get too pruny. Sam, you can learn the joy of getting him into his pajamas.”

“Oh, I can’t wait.”

The Next Day

“What happened?” said Y/N. Good. She was home and she could yell at Sam properly.

“He had an accident and then he started yelling and he got even louder when I put him in a diaper. He hasn’t been quiet since,” said Sam.

“Dean, I know we had a deal but you had an accident. I think you’re too little to-“

“It was his fault,” I yelled, pointing at Sam. “He forgot to...I will destroy you both if you-“

“When’s the last time you took him to the bathroom?” she asked Sam.

“I don’t know,” he said.

“Has he gone since I took him at breakfast?” she asked. Sam looked away and thankfully Y/N was getting with the program. “You have to take him Sam. Of course he had an accident. His bladder isn’t as big as yours.”

“I don’t get why he just doesn’t wear the diapers,” said Sam.

“I will kick your ass when I’m big again Sam,” I growled, Y/N settling me on her hip.

“He doesn’t like them and you upset him. This is a baby but it’s Dean too. If there’s a shred of adult in there, we’re going to try to make him feel like himself,” she said.

“Best fucking girlfriend ever. I so owe you,” I said, leaning down to give her a hug.

“Well...don’t piss on me again,” grumbled Sam.

“Maybe now you learned your lesson.”

Three Months Later

“Hi Dean,” said Y/N when I crawled over. “What’s up?”

“Guess what I figured out how to do,” I said, grabbing her leg and standing up, able to take a few shaky steps on my own before falling on my butt. “I’m mobile.”

“Well look at you! You’re growing up all over again,” she said, scooping me up to sit in her lap. “We made it halfway there. Just another few months and you’ll be big again.”

“Trust me, I’m counting the days. Figuratively I mean since telling time is a bit hard right now but you know what I mean,” I said, Y/N humming. “Uh oh. That’s the bad hum.”

“Don’t worry, Dean,” she said. “Sammy’s just checking on a last ditch effort. I’m not getting my hopes up is all. Besides, you and I are going to have my favorite thing right now.”

“It’s nap time,” I said, grunting when I started to get carried. “At least this part isn’t too bad.”

Something was off when I woke up twenty minutes later. Y/N had her head in her hands and was crying on the bed.

“Sam,” she said into her phone. “You said six months.”

“Rowena is going to work on a counterspell to get it to reverse back,” he said.

“But she only has three months left or else he’s gonna he a baby permanently. I don’t want to raise my boyfriend. I’m barely keeping it together,” she said.

“Rowena is the best witch there is. She’ll figure out what the other witch did,” said Sam. “Just try not to let Dean see you upset or he’ll think something’s wrong.”

“Too late for that,” she said, moving her hands away, looking over at me with a sigh. “I’ll see you at dinner.”

“So I’m fucked,” I said, trying to cross my legs in the crib but making no progress. “Fuck.”

“Dean,” she said. She picked me up and gave me a hug, wiping her face off when she pulled back. “Don’t worry. I will always take care of you. Big or small.”

“I really hope Rowena can figure this out.”

Three Months Later (Almost)

“Big day today Dean,” said Y/N, rubbing her hand over my head.

“Yeah. In about an hour I’m a baby for good and I’m sort of thinking that means I’m going full baby mode and I’m gonna forget everything and everyone and how to even talk…” I said, Y/N shushing me.

“Don’t cry. I hate seeing you cry,” she said. “And if things go south today...don’t be scared because we got you.”

“How’s he holding up?” asked Sam, Y/N giving him a sad smile. “He has to understand if he’s so upset.”

“I know. I know part of him is an adult in there,” said Y/N. “Rowena’s in the library sweetie and she’s going to keep working as long as we got left.”

“I think I’ve got it,” said Rowena, rushing into the kitchen. “I need materials though.”

Sam took off with her, both of them taking far too long in my opinion. Y/N eventually plopped me down in the high chair in the library, Rowena shoving a mixture in a bowl at Y/N.

“He has to drink it,” she said.

“Dean, don’t throw this up,” said Y/N, tilting the bowl, some of it dribbling down my face. “Get a damn bottle. Now!”

“Come on. At least a sippy cup, not the stupid bottles again,” I grumbled, Y/N taking one from Sam, pouring the slop inside and twisting the cap on.

“For once, do not fuss with this thing,” she said, putting the bottle to my lips. I wanted to scoff at her but she squeezed it and liquid flooded my mouth. It tasted awful and she just kept squeezing more in, forcing me to swallow. I drank most of the bottle down as a timer went off, all three of them jumping about a foot back.

I peeled open an eye, bottle hanging from my mouth and ass currently sat on the floor and pieces of broken high chair.

“Dean?” asked Sam. I spit the bottle out and stood up, blinking down at myself.

“Excuse me but I’ve had to piss the last two hours,” I said, moving past them all for the bathroom, ripping the obnoxious baby outfit off and sitting down. “Oh, I never thought I’d be so happy to be using the bathroom again.”

Reader POV

“Hey, Dean?” you said, walking into the bathroom, Dean currently walking around the space in a pair of boxers, happy as could be. “You doing okay? All adult in there again?”

“Yes. Thankfully,” said Dean. “I’m just enjoying things like brushing my own teeth and shaving and oh yeah, I can actually talk again.”

“So how much-”

“I understood everything. I acted a lot like a baby whether I wanted to or not but I understood it all,” said Dean. “Thank you so fucking much for not making me use the damn diapers.”

“Well...I figured there was some of you in there,” you said. “Sorry about the bottles. And baby food. And pacifier. And the onesies.”

“Eh, they grow on you,” he said with a shrug. “I wasn’t a very well behaved baby.”

“You kept out of trouble for the most part,” you said, wrapping your arms around him, so glad to have him back to his normal size.

“I want a burger and steak and sweet potato fries,” said Dean.

“Okay. You can have all that,” you said with a laugh. “You can even drive to the store if you want.”

“Oh, I am looking forward to it.”
