Bucky wasn’t ready to be a dad, he knew that he wasn’t and he had voiced that to Y/N many times. But the sweet smile she put on, cupping his jaw– firmly but with all good intentions– and whispering just how amazing he’ll be. That voice of reason. Whenever he doubted himself, he’d repeat what she always told him.
“James Buchanan, how dare you think so low of yourself. You won’t be like your father and you’re not a broken vase getting replaced by a new one. You’ll be a wonderful father."
So, he went on thinking and believing every word. As time went on and Y/N’s stomach grew, so did Bucky’s insecurities. He was always careful, always worrying if he’d be good enough. He worried about whether or not their baby would be ok with the serum running through their blood. In the end, Bucky had nothing to worry about.
On May 15th, 2025, Luka Buchanan Barnes was born. A beautiful baby boy, healthy ( thank you serum ) and had two sets of lungs on him. His baby blue eyes and smile combined to get him anything. Especially from Y/N. The first few months were filled with both parents staying awake, their son on their chest or in the crib.
The year was smooth, Luka hit the milestones needed for his age. The Y/H/C mop of hair becoming thicker by the day, and giggles louder than his cries. Everyone was content. Well, that was, until Luka started to talk.
The first time Luka talked was while Bucky and Y/N were arguing over something small. Why was there no diapers, their voices raising as Luke’s eyes darted between them. His Cheerios seemed more and more less appealing as his mother and father continued. His brows drew together, eyes narrowed. He picked up his bowl, raised it and tossed it towards his mother.
Bucky and Y/N stopped in shock, mouths open and eyes wide. They both turned toward the boy, who was now happy about the attention, and they smiled. Bucky raced forward and picked up, raising him in the air as he laughed.
"I’m so proud of you, Luka! You said your first word!” he planted kisses all over his face. “You’re amazing, handsome, talented, baby boy!”
Y/N watched on with a grin, biting her nails. Her boys, so happy. Oh, gosh, what troublemakers they would make.
The next few weeks, Bucky would sit with his son and try to teach him words. Luke had the shortest attention span and would rather play with Bucky’s arm than learn stupid words.
On the best day of Bucky’s life, it started as any other. It was a Sunday so Sam came over to watch football. Y/N was going out with Misty and Pepper to have a girls’ day, to let the boys have fun and the girls have theirs. Kisses were exchanged and warnings of no funny business. Both men agreed with eye rolls.
At half time, Bucky sat down on the floor with Luka. The boy shakily stood with his hands fisted on his father’s shirt. Bucky drank his beer as well kept a soft hand on Luka’s back.
Sam watched his best friend closely, tilting his head. “What have you taught him so far?” he finally asked.
Bucky raised a brow, looking toward Luka with a soft smile. “A few words, dada, mama, water, potty. Simple stuff.” he shrugged. “Y/N doesn’t want to force him to learn too much at once.”
“Oh. So he’s not a piece of shit like his dad?” Sam smirked.
Bucky glared, huffing. “You know what, Wilson? Fuck you!” both men laugh loudly. “You’re such a fucking ass.”
Sam sighed, “Had to get it from someone.” he looked back towards the TV, tsking. “Football sure isn’t what it used to be.”
Bucky chuckled. “Sam, they’re still a bunch of jocks prancing around in tights.” he looked to Luka who looked thoroughly frustrated. “Want to jump, hm? Is that what you want?”
Bucky stood, carefully placing his beer down and grabbing both of Luka’s hands. He started to lift and then go down. The two smiling and laughing, Sam watched Bucky with weird eyes. Then to Luka who stared at his father like he was his world.
“Ever taught him a naughty word, Buck?” Sam asked, his posture more laid back.
“A naughty word?” Bucky repeated slowly, swaying Luka slightly. He scoffed. “Yeah, right. Do you know how pissed Y/N would be hearing, ‘Shit’ come out of his mouth? Sam! She hates it when we say it.”
Sam nodded slowly, “But–”
“–It’d be so much fun!”
Bucky nibbled on his bottom lip, then looked towards Luka who now tried stomping on Bucky’s shoe. He sighed and gave in with, “Ok. Just one word.” What bad could it do?
Apparently, it could do a lot. Luka was now repeating, “Fuck!” over and over again while Sam rolled around in laughter and Bucky pulled out his hair. Teaching a 1 year old to say fuck was not a good idea, at all. Hearing it the first time was hilarious, his tiny voice released the uck but when the f came out. Bucky felt his stomach twist and his heart drop. He was so dead.
“F-Fuck! Fuck!” the boy said happily, his hands clapped loudly.
Sam wiped tears from his cheeks, his breathing laboured. “He-He won’t stop!"
Bucky’s eyes were wide, his hands held onto his son’s sides. His face was pale and mouth wide open, he couldn’t think of words. No words can explain how amused and horrified of this he was.
He shook his head, "No, Luka, Luka, say fun! Fun!” he tried desperately. “Fun! Say it daddy, fun!”
“F-Fu..” Luka frowned, pulling his father’s hair. “Fuck!”
Sam laughed even louder while Bucky cried, holding Luka to his chest. “Y/N gonna kill me, I’m dead. This is the last I’ll ever see of him.” Bucky muttered, rocking with him.
Sam patted his back, “At your funeral, when Luka needs to talk, he’ll say his favorite word. Fuck!” he promptly laughed again.
Luka pushed his tiny arms against Bucky’s chest, Bucky pulled away thinking he was squishing Luka too hard. Luka pushed his father’s cheeks together, Bucky raised his brows.
“Dada…fun!” Luka giggled. “Fun!”
“Hell yes, Luka!” Bucky placed kisses all over his face, laughing. “Yes!”
“Dada what?!” there in the doorway was Misty and Y/N. Y/N looked beyond mad, face red and glaring at the two men on the floor. “James Buchanan, what?”
It’s easy to say, Bucky wasn’t allowed to teach Luka alone.
