Non-sexual age regression. This will just be a random collection of one shots including TK and Owen. May add more from the 126 as time goes on, but for now will focus on them. Though, Judd and Owen will be proper friends, as they should be. I won't go into the whole how they moved as it really is nothing different, Owen is just now his caregiver. I've written that plot a lot in other fics and there's no new way for me to really write it without it being boring for you guys to read and me to write haha.

The backstory is the nearly same: TK and Owen move to Austin as an intervention of sorts. Owen is TK's caregiver. I've changed things so Owen's cancer is in remission and won't be an issue any longer. Gwyn has also passed away by this point.

I promise I'm still writing all my verses. This one I may not update as much, but I will try!

Feel free to leave prompts or ask me questions! I am on Tumblr and love communicating on there, as well as in the comments!

Owen hangs back as he watches TK play air hockey with some of the crew. He glances at the clock every few seconds. He knows TK can see it too. Still, he just fist bumps when he scores on Marjan's side.

He's really going to make his dad do this?

Owen walks over to the table. Marjan tries to shoot on TK's side, but he blocks it easily. She shakes her head and looks over at her captain.

"Your son's good."

Owen nods. "That he is." He looks at TK, who stays focused on the game. "TK."

"Yeah?" He slides the puck over and Marjan shoots it back.

"Can I speak to you in my office?"

"I'm a little busy, Dad," TK says, narrowing his eyes as he tries to find a way around Marjan's paddle.

"I can see that, but we need to talk."

TK ignores him. Marjan raises an eyebrow but continues playing. Owen clears his throat.

"Tyler."

That gets TK's attention. He grumbles as he looks up at his dad.

"What?"

Owen clicks his tongue. "My office. Now."

"The game…"

"We can play later," Marjan says. "Go talk to your dad."

"We can finish it now."

"I should probably hit up the showers before someone else jumps in," she says, squeezing his shoulder.

Owen nods as a thank you. TK watches her walking away, his lips slowly forming into a pout. He drags his feet as he follows his father into his office. Owen shuts the door.

"It's time to get ready for bed."

TK's mouth drops open. "No way! No one else has to go to sleep."

"That's not relevant to this conversation. It's getting late and we've been a little quiet tonight. I'm expecting we may get some calls around midnight. In that case, you need your rest."

TK shakes his head. "No, I'm fine! I'm not little. I don't need a bedtime."

"We've discussed this, Monkey. In order to keep you in the best mental and physical state, you have a bedtime."

TK narrows his eyes, folding his arms over his chest. Owen sighs as he pinches the bridge of his nose. Occasionally, TK will give him a hard time about going to bed at home but is usually persuaded. Since they started at the 126, he's resisted it every overnight shift.

"This isn't up for discussion," Owen says. "You're going to brush your teeth, wash your face, go potty and get ready for bed."

TK's cheeks burn. "You don't need to remind me to go to the bathroom! And I'm not wearing some stupid pull-up either."

"Yes, you certainly are. You don't want to have an accident do you?" TK glowers at him. Owen tries to hide a smile. His son thinks he looks threatening right now, when he actually looks adorable. "Show me you can be a big boy and do these things for yourself."

"I'm going to stay up."

"No, you're not," Owen's voice grows firm. "TK, I just said I'm giving you a chance to be a big boy, yes? If you can do all that on your own, great. If not, I can help you."

"You wouldn't do that."

"I'd get you ready in my office, but I wouldn't hesitate to escort you to the bunks."

TK stares at him for a moment. Owen remains firm. They discussed this before they moved here. Owen wants to give TK his independence, but he will step in as needed. The best way for TK to be alert for calls is this bedtime and naps, if the day permits. He knows it's not fun. Owen can also acknowledge that it may be a bit embarrassing but the odds of anyone noticing are slim. Some are already sleeping anyway.

When Owen doesn't back down, TK snatches his bag and storms for the door.

"Remember…"

"I'll use the stupid bathroom."

"Do you want help with your pull-up?"

"No!" TK snaps.

"Tyler," Owen warns. "You don't have to like me right now, but you will watch your attitude."

TK scoffs before exiting the office. Owen sighs, rubbing his hand over his face. He waits a little bit before heading for the dormitory. Despite the showers running, all beds are exits the bathroom, a little bit of toothpaste on his chin. He's wearing the standard pajamas. Owen can make out the edge of his pull-up over the band of his pants.

"Good boy."

TK rolls his eyes. "Why don't you just diaper me and put me in footie pajamas?"

"If you wanted me to, I would."

TK shakes his head, poking out his tongue. Owen holds back a chuckle.

"Want me to tuck you in?"

"I can manage on my own."

"Alright. I'll be in my room for a couple of more hours if you need me."

Owen gently cups his cheeks and rubs them, moving to playfully grab his ears as he usually does. TK pulls away from him, once again turning bright red. Owen shakes his head.

"You don't want PB?"

"Dad! I don't need a stupid stuffed animal," TK whines. "I didn't even bring it with me."

"Alright, alright. You head on off to bed. I love you."

"I love you too."

TK hesitates, then kisses his dad's cheek. Owen smiles, watching after him as he heads to his bed. He makes sure he gets under the covers and Buttercup lays next to his bed before heading back to the office.

Owen digs through his own overnight bag and plucks out the stuffed monkey. He bought it for TK when he was about 3 years old. The little boy was very clingy. They couldn't put him down for more than a few minutes without him whining and asking for "up". TK named the monkey "Peanut Butter", after his favorite smoothie but started calling him PB. Because TK went by initials, so did his monkey.

TK used to carry his monkey everywhere. That tapered out when he was 6 or 7, but he still slept with it. To this day, regardless of space, he's cuddling his monkey at night.

Except for work, it would seem.

Owen still brings it, just in case. He won't embarrass TK or force it on him, but a dad has to come prepared.

There's only an hour left in the shift when Owen heads into the garage. Everyone is attending to their last minute chores. It's on Paul, Mateo and TK to clean the truck. Owen flicks through the clipboard when he sees Paul and Mateo finishing up the bottom. He raises a brow.

"Where's TK?"

"I think he's cleaning the inside."

Owen nods and is about to check, when he sees TK standing on top of the truck. His head is mere inches from the ceiling as he walks towards the ladder. Owen's eyes widen. He tries to keep his voice calm, not wanting to spook him.

"TK," he says. His son skids backwards a bit. Owen's heart does a somersault. "Get down from there."

"I'm just cleaning the top."

"You know you're not supposed to do that. Paul or Judd are in charge of that."

TK rolls his eyes. "I can do it."

Paul peeks his head around. "TK, listen to your dad. I was going to get to that next."

"I can do it!" TK argues. "It's really not a big deal. It'll take 2 seconds."

"Tyler Kennedy," Owen warns. "You know I don't want you up there. If you fall, you're going to get seriously hurt."

"I'm not coming down until I'm done."

TK kneels down and begins scrubbing the top of the ladder. Owen clicks his tongue. He's used to stubborn TK. Usually, it's not over something so unsafe. It really doesn't matter in the end.

"Tyler Kennedy Strand." Owen watches him tense up. "You have until the count of 3 to get down or you will stand in the corner of my office."

He watches TK's cheeks light up like a Christmas tree. Owen doesn't pay that any mind. Mateo peeks his head around the truck, intrigue in his eyes. Paul quickly pulls him back. Owen hears him mumbling something about minding his own business. Mateo starts to argue, but the simple mention of Judd silences him.

"1…" Owen starts. TK remains in place. "2…." Owen sighs when he doesn't move. "This is how we're ending the shift, TK? Really?"

"I thought you were counting to 3," TK mutters.

Owen scoffs. "3. Get down now, or it'll be much worse."

"Dad…"

"Tyler Kennedy, if I have to come up there, I can promise a timeout will be the least of your worries. Now, slowly come down here."

TK is still for just a moment longer. He finally scales down the side. Owen rushes over, ready to grab him should he fall. Luckily, TK lands on his feet. Owen grabs hold of his wrist, ignoring his wiggling. He looks over at Paul.

"Do you need me to bring him back out here once his timeout is over?"

Paul shakes his head. "No, Cap. Truth is, the roof is all that's left. I'll attend to that now."

"Of course. And I'm sorry about all this."

TK wiggles. "Dad…"

"Are you going to apologize to Paul?"

TK bites his lip. As much as he can be disrespectful to his dad at times, he is better about the team. TK ducks his head. Owen leads his head back up, nudging his ribs.

"Sorry, Paul," he mumbles. "Sorry, Teo."

Paul nods. "You need to be careful, TK. You could've easily fallen off and gotten hurt. Don't do that again."

TK's cheeks are crimson by this point, but he mumbles a "yes, sir". Mateo shoots him a sympathetic look.

Owen keeps a hold of his son's wrist as he leads him up to his office. TK tries to hide behind him, though it's a fruitless task. Judd seems to be the only one who notices and he quickly looks away. Owen shuts the door behind them. TK yanks away from him.

"You completely embarrassed me!"

Owen shakes his head. "You were standing on top of the truck, Tyler. Was I really supposed to let you do that?"

"You pretend like I can't do anything, but I can!"

"There is a lot you can do," Owen says, trying to stay calm. "But there's some stuff you can't. We've been over all this. I think you need to spend some time in the corner reflecting on that."

"No! I'm not sitting in the stupid corner like a toddler! I'm an adult!"

Owen sees the exhaustion in his eyes. His lips are quivering as he stomps his foot. Little by little, tears fall down his cheeks. Owen tries to give him a hug, but he's pushed away.

"No! No hugs!"

Owen nods and takes him by the hand. He wordlessly leads him to the corner. TK drops onto his bottom. He kicks his legs and flails his arms. Owen stands above the tantruming boy. He whines and lets out little screeches every so often. The big, fat tears spill down his cheeks as he sniffles and screams. He's still in his black uniform, shirt tucked in and belt done up. If he's going to drop, that's not going to be comfortable for long. Owen also knows better than to try to change him mid-tantrum.

He allows TK to cry and scream, putting down the blinds to give them some privacy. At one point, it would've broken his heart to listen to this and he'd try to jump in and calm him down. Now he knows, sometimes it's best for TK to self-regulate. Owen will get nowhere when he screams.

TK isn't making out any words right now. It's a true, God's honest tantrum complete with incoherent whining and lots of kicking. TK punches the floor and cries harder. Owen sits beside him.

It's another few minutes of shrieking until it slowly morphs into just whining. Then hiccups. Owen rubs his back, listening to make sure his breathing regulates.

"Inhale," he whispers. TK complies. "Exhale." Owen smiles when the air releases from his son's nose. "And again. Inhale…"

They go through the process a few more times until the hiccups are gone. Owen reaches over and grabs some tissues from his desk. He wipes at his sticky face, softly cooing.

"Blow for me." TK allows him to hold the tissue to his nose. "That's a good boy. Feeling better?"

TK rubs his eyes with his fists. "Uh huh."

"Now, do you want to tell me why you've given me a hard time the past 24 hours?"

"I'm sorry," TK whispers.

"I appreciate that, but I'd also like to understand where you're coming from." Owen caresses TK's hair. "Can you use your words?"

TK takes the tissues from him and blows his nose again. He dabs at his eyes with a fresh one.

"I…I don't want to look like a little kid."

Owen sighs. "TK, insisting cleaning the top of the truck and refusing to come down when asked doesn't exactly help."

"I just wanted to show I can do things!" TK argues. "Everyone knows I'm Little."

"You're not the only Little here, bubba."

"I'm the only one with my dad here. Everyone probably thinks I get special treatment and don't have to do things because you're my boss."

Owen frowns. "Has anyone said that?"

"Well…no, but I know they have to think it."

"You're not the only Little with accommodations," Owen repeats. "Yes, I may be your dad, but I'd feel the same if Mateo or any of the other Littles were doing something so reckless or fighting against the accommodations they need. Such as their bedtime."

TK sighs, looking down at his shoes.

"I don't want them to look at me like a baby," he mumbles.

"They don't," Ownen promises. He caresses his hair. "They know what a smart, dedicated, hard working guy you are. You put in just as much effort as the rest. You may be small sometimes, but that doesn't take away what you bring to the team. Acting out isn't going to prove much, except that you have a dad that will tell you when you're being naughty."

TK bites his lip as he looks up at him.

"Sorry," he whispers.

"I know you are." Owen rubs his back. "I also know you're very tired. You only had 2 hours before we had to go on that call. Did you get any sleep after we got back?" TK shakes his head. "My poor little Monkey. I think someone needs a nap."

TK rubs his eyes. "We have to go home soon."

"And we will. Let me just do a final rounds then I'll get you ready, okay?"

"'Kay."

Owen bends down and picks him up, carrying him to the couch. He lays him down and kisses his forehead.

"I'll be right back," Owen promises. He reaches into the overnight bag and pulls out PB. TK's tired eyes light up.

"You brought him," TK whispers.

"Of course I did. How could I forget my little monkey's favorite?"

This time when Owen rubs his cheeks and plays with his ears, TK doesn't pull away. Instead, he sleepily giggles. Owen kisses his nose.

"Stay right here, give Monkey lots of cuddles for me."

"'Kay, Daddy."

Owen makes sure his rounds are quick. The next shift is already trickling in by the time he heads back up to the dormitories. He takes the time to get himself ready first before heading to the office. TK is awake, though just barely. Owen grabs the changing supplies along with a pair of light green two-piece pajamas with little monkeys on them.

It's easy to get TK out of his belt and pants. Owen notes his briefs are wet, but he's too young to notice.

"Does Daddy's boy want some lotion?" Owen coos.

TK nods. "Uh huh. Please, Daddy."

"Then that's what we'll do."

Owen gets him all the way undressed before grabbing the strawberry lotion. He starts at TK's neck and rubs it down, making sure every inch is covered. When it comes to his bottom, he grabs the rash cream and gently tends to it. TK plays with his monkey all the way. Owen slides on the fresh pull-up.

"You can put on big boy underwear after your nap if you'd like," Owen says, knowing he likely won't. "But for now, so you don't have to sit on the potty."

"Too sleepy," TK mumbles, holding PB tight."

"I know, Monkey. Daddy knows."

"You take good care of me," TK mumbles, his fingers heading for his mouth.

Owen smiles, stroking his baby soft cheek.

"And I always will."

Owen gets him in the pajamas quick. He removes TK's fingers and puts in his pacifier, clipping it to the shirt.

"Do you want a bottle before we go? It may help you nap in the car." TK nods, his eyes dropping. "Hey, hey, keep those baby blues open for me, hm?"

TK yawns, nodding his head. Owen goes about whipping up a quick bottle with the water from the fridge, heating it up in his espresso machine. He mixes it in with the special protein formula and shakes it up nice and good.

He walks back over and sits TK up. The little one nearly loses his monkey in the process and clings on tight. Owen moves him onto his lap. TK latches on right away, drinking quickly.

"Slow down," Owen says with a slight yawn. "I think Daddy's going to take a nap with TK." His son nods, only slowing down a bit. "We had a very long shift. You did so well. My brave boy."

TK smiles around the nipple. Owen blinks a few times. He'll be good to drive, it's not too far. Good thing both are in their comfy clothes and can knock out the second they hit the "big bed" as TK calls it. Owen has read the conflicting reports about co-sleeping but he's never going to deny his son any bit of comfort. There were too many nights he didn't get to tuck him in during his first childhood. That won't continue now. It's why Owen makes sure they work all the same shifts. TK will never be far from his daddy when he needs him.

Eventually, Owen hears the sound of TK sucking on air. He sets the bottle down and moves him up a bit, delivering some firm pats between his shoulder blades. It takes a few minutes to hear a decent burp that's not quiet in the slightest. TK giggles. Owen pulls a funny face, adjusting him the right way. He brushes the spit up away from his chin.

"It's not polite to find your burps amusing," Owen only half-heartedly chastises.

TK burps again, once again bursting into a fit of sleepy giggles. Owen chuckles and stands up. TK wraps his legs around his torso and arms around his neck, laying his head on his shoulder. Owen tosses the dirty bottle into a side pocket of the bag before hoisting it over his free shoulder.

Owen carries him downstairs and through the firehouse to get to the back parking lot. TK is sucking on his pacifier and holding his monkey tight, wearing childish pajamas that don't exactly hide his pull-up.

And yet, he's content. Full and sleepy, but content.

Owen knows no one will bring this up come the next shift. If TK is big, he'll be an equal part of the team. He just hopes his son can see what everyone else does soon.
