Chapter Text
‘Well crap,’ Dean thought, staring at the positive pregnancy test.
The digital display didn’t change, no matter how hard Dean stared at it. The word pregnant stared right back up at him.
He slid down the wall, the cool tile pressing through his pants, the plastic stick burning in his hand. He felt entirely out of his depth.
Jack was barely five months old, a tiny, demanding little pup who still woke up three times a night crying for milk. Dean's body still felt soft in places it never used to be, his hips holding the remnants of aching from Jack’s birth.
He hadn't even gotten his heat back. Not a single drop of slick, no spikes in his pheromones, no feverish need to nest. The doctor had told him the nursing could delay it, keep his cycle suppressed while his body recovered. He’d taken that as gospel.
Clearly, he’d been an idiot.
He and Cas had only just cleared the postpartum hurdle a month ago, finally finding the energy and the quiet moments between Jack’s naps to actually touch each other again. It hadn't been about trying for a baby; it had just been about them. Two tired parents clinging to each other in the dark, seeking comfort after months of operating on survival mode. It had been gentle, easy, and completely unprotected because Dean truly believed his body was offline.
And now, a month of tentative, stolen intimacy had caught a second pup.
From the apartment, Dean could hear the distant, comforting rumble of an engine, his dad revving a customer’s truck, and the distant rhythmic clatter of tools. Right outside the bathroom door, he heard the deep baritone of Castiel humming a wordless melody, to a cooing Jack in their living room.
Cas was right out there, utterly oblivious to the fact that his Omega was currently having a minor existential crisis over a tiny piece of plastic.
Two under two. A five-month-old pup, and a fresh embryo currently making itself at home in his womb.
"Cas," Dean called out, his voice a little tighter, a little more breathless than he intended. He cleared his throat, trying to channel some of that classic Winchester grit, though his heart was hammering against his ribs. "Cas, get in here for a second."
Castiel was hardly surprised and, in fact, had seemed deeply satisfied by the news. It was a popular belief that pups should be close in age. It fostered a stronger bond between siblings and was standard practice for ensuring an Omega stayed bred while young. An Omega's fertility was a powerful thing, especially when the bond with their Alpha was healthy. The unexpected pregnancy was a positive sign, in Cas’s opinion. He had intended to speak with Dean about trying for their next pup by the end of the season regardless.
Over the next few months, the initial uncertainty slowly gave way to acceptance. It was hard for Dean to stay anxious when his Alpha was practically turning himself inside out to keep the household running. Cas had wanted this. Cas had been planning to have a second baby. They’d make it work.
Castiel stepped up completely. He structured his schedule around Dean’s needs, be it morning sickness or Jack’s naps. He became a shadow in the best way possible: tracking Dean’s caloric intake, taking over all the domestic chores, brewing prenatal teas, and lifting Jack away to burp, change, and rock him the second feeding time was over. Cas’s deep, soothing Alpha purr became the soundtrack to their sleep deprived nights.
Dean had started to come in to the garage again for part-time relief. Several afternoons a week, the roles would shift. Dean would emerge from the house, looking more like a mechanic than a nursing, pregnant Omega.
Castiel would take Jack and allow his mate time to be just Dean again. While he worked, Cas loved on Jack. He bonded with him in the ways he believed were essential; reading to him, playing gently, and encouraging the pup to reach his developmental milestones.
Jack was a feisty little one, inquisitive of the world and eager to try solids, enjoying food as much as his Omega daddy.
When the sun began to dip below the horizon, Dean would wipe the grease from his hands and retreat back to his mate. He’d find Castiel sitting in the armchair, Jack curled against his shoulder, both of them smelling of the Alpha’s musk.
"He been good, Cas?" Dean asked softly as he leaned over to press a kiss to Jack’s forehead and then to Castiel’s jaw.
"He’s our pup. He’s always good," Castiel replied, his hand came up to rest possessively on Dean’s hip.
They eventually told John who paused in his tracks. He had certainly noticed Dean glowing more than usual, clearly contended and secure. Still the older Alpha’s rugged face etched with a mixture of understanding and immediate paternal concern.
"Another one?" John asked that evening, pulling Cas aside near the back parts-counter while Dean was busy putting Jack down in the office.
John was an Alpha through and through. He understood the instinctual drive to secure a family with children close in age. Heck, he and Mary would have had more, given the chance. In their world, a fertile Omega and a strong Alpha producing pups back-to-back was a sign of a thriving relationship. He didn't fault Cas for wanting to claim his family's future.
But Dean wasn't just any Omega. He was John’s firstborn.
"Cas, I get it," John said, his voice low, his eyes cutting toward the office door to make sure Dean was out of earshot. "But my boy's body hasn't even fully healed from the first one. Carrying a second pup while the first is still on the tit takes a heavy toll."
That was true. Balancing a nursing infant while a second baby was in the womb was rapidly wiping out Dean’s reserves. Unfortunately, the younger Alpha’s conclusion was not one John was expecting.
Cas watched the toll pregnancy and nursing was taking on Dean. In the his mind, the health of the unborn pup and the recovery of his mate were paramount. Jack was old enough for formula and had been taking solid foods for a few months. It was time for a change.
But when Cas gently suggested weaning, Dean shook his head. "He’s not ready, Cas. I'm not ready. Just let me do this," he insisted, shielding the baby against his chest. To Dean, nursing Jack was the one piece of normal control he had left in the middle of a whirlwind year.
Frustrated by Dean's stubborn refusal to prioritize his own health, Cas let his dominant Alpha instincts take the wheel. He made the hasty decision to ensure obedience for the sake of Dean’s wellbeing. Cas packed Jack’s diaper bag and took the boy over to John’s house, intending to keep them separated for a few days to force Dean’s milk to dry up.
Naturally Dean had not been happy with him. The silence in the house was deafening. Dean spent the evening pacing the nursery, his chest tight and aching with the physical pressure of his milk coming in with nowhere to go.
However, the physical ache was nothing compared to the emotional agony. Every time the clock ticked past Jack’s usual feeding time, Dean’s heart broke, convinced his little pup was crying out for him, wondering why his daddy had abandoned him.
At his house, John watched his grandson fuss and reject the taste of formula. Each hungry whimper, brought horrible reminders of six-month-old Sammy doing the same after Mary’s death. He couldn’t imagine what his son-in-law had been thinking or the state Dean must be in back home. With a defeated sigh, the Alpha picked up the phone.
Castiel found Dean curled on the rocking chair of the nursery, clutching Jack’s favorite blanket. The scent in the room was sour with the tang of Dean’s distress and the heavy cloy of a nursing Omega in pain. Dean didn't even look up; he just let out a sniff of misery.
Castiel’s resolve crumbled. A decision he’d thought would be in Dean’s best interest had been a grave error. How wrong he was; instead of making this pregnancy easier, he’d hurt Dean, hurt their pup, and judging from the buzzing in his pocket, most likely given his father-in-law grief.
Cas stepped out of the room to answer John’s call.
"You're being too hard on him, Cas," John said, his low voice tight over the line. “You’re fighting his nature. An Omega’s biology doesn't just shut off because you tell it to. His body is yelling at him that his pup is missing. You can't just wrench a baby away and expect him to sit tight."
The harsh reality of John's words, paired with the miserable scent drifting from the nursery, filled Cas with guilt. He had to remedy this.
Stepping into the dim room once more, Castiel pulled Dean up into his chest. Dean didn't fight him, but he didn't lean in either; he was simply too sad.
"Dean," Castiel murmured, his hand coming up to stroke the back of Dean's neck. He released a heavy wave of comforting, apologetic pheromones. "I am sorry. I went too far. We will bring Jack home tomorrow, and we will wean him slowly. Together.”
The Alpha reached for the manual pump sitting on the changing table, a tool Dean had used during his garage shifts, and handed it to him. "Go on and pump," Cas said gently, lifting Dean's hand to place it over the plastic shield. “We won’t dry you out overnight. It was much too abrupt."
Dean looked at the pump and his eyes filled with fresh tears, but these were born of relief. He leaned his forehead against Castiel’s shoulder. "I just miss him, Cas," he whispered, the physical relief of pumping finally beginning to soothe the ache in his chest. "I feel like he’s calling for me and I’m ignoring him. It hurts."
"I know that now. He will stay at your dad’s for tonight so you can rest, but I’ll get him first thing in the morning. We’ll reduce the feedings one by one."
Dean nodded, his body finally beginning to relax.
True to his word, Cas brought Jack home the very next morning. The process of weaning became less about a hard-and-fast rule and more about a gentle redistribution of comfort. Cas realized that Jack’s midnight wakings weren't about hunger anymore; at nine months old, the boy was well-fed on solids and milk during the day. It was entirely about comfort, and Dean’s body was paying the price for every middle-of-the-night soothing session.
The next night, when Jack’s high-pitched cry pierced the quiet bedroom at 2:00 AM, Dean instantly went to throw off the covers, his instinctual response kicking in. But Cas’s heavy arm settled gently over his waist, pinning him softly to the mattress.
"Stay," Cas murmured into the dark, his voice low. "Let me go to him."
"Cas, he’s just gonna cry for me–“
"Then I will hold him through it," Cas said firmly, kissing Dean’s mouth before slipping out of bed.
From the master bedroom, Dean lay awake, his arms wrapped around himself, his heart tensing every time Jack let out a confused cry for him. The first night, Jack cried for forty minutes, a stubborn Winchester through and through. But Cas never wavered, his low humming and steady rocking never missing a beat. He patiently tucked Jack’s head into the crook of his neck, right against his scent gland that pulsed with a calming aroma.
By the sixth night, the crying stopped completely. Jack would simply let out a tiny, shuddering sigh, settle down and surrender to sleep, comforted by the solid warmth of his Alpha sire.
For the next several weeks, the bedtime routine shifted. Dean would feed Jack his dinner and spend some quiet time playing with him, but when the pup’s eyes began to droop, Castiel would step in.
"See, Dean," Cas whispered one night as he finally transitioned a sleeping Jack into the crib. "He doesn't just need the milk. He just needs a little extra security.”
The transition to bottle feeds also helped slow Dean’s supply. At first only pumped milk then slowly adding formula until Jack was comfortable with a formula only bottle.
With the emotional hurdle cleared and the midnight comfort successfully redirected to Cas, the physical process of weaning became incredibly easy. Within two weeks, Dean’s milk dried up naturally, leaving his body free to dedicate all its remaining energy to the stubborn, growing pup currently kicking against his ribs.
One evening after Jack had easily been tucked in by Castiel without a single tear, Dean met his Alpha in the hallway. He looked up at Cas, his expression soft and full of a tired gratitude.
"You were right, Cas," Dean murmured, leaning his forehead against the alpha’s chest. "He just needed to know you had him. We both did."
Castiel wrapped his arms around Dean, pulling him close for a deep kiss.
Now that his body sustained one pup, Dean noticed this second pregnancy was proving to be much smoother than the first. The bone-deep nausea that had plagued Dean with Jack was absent, and his joints didn't ache half as much, his body seemingly remembering the path it had traveled just months prior.
Because the pregnancy had happened so quickly and his cycle hadn't fully reset, the dates were a bit of a guessing game. Every time they went in for a scan, the stubborn little pup was positioned completely wrong, curled up tight refusing to be measured properly. Dean grumbled about not knowing the due date.
Cas offered a small smile, his thumbs digging into the arches of Dean’s feet. "Does it matter, my love? We’ll be ready all the same."
"Easy for you to say," Dean huffed, crossing his arms over his chest. "You’re an Alpha. You’re just happy we’re having another baby. I’m the one who has to mentally and physically prepare myself for labor…again."
"I’m sorry, sweetheart, you’re right. If it helps, my instincts tell me the pup is strong, healthy, and very stubborn, just like their Omega Daddy."
"Yeah, yeah, blame my genes," Dean grumbled playfully. He still hated the lack of control, the blind spot in his planning, but with Cas's help, it was getting easier to just let his body do what it was built to do.
It was an early December morning when their little pup made an appearance.
Soft mewling that sounded like music to Dean’s ears after laboring for four hours. When Castiel leaned down, his face a mask of awe-struck reverence, and whispered, "It’s a girl, Dean," the exhaustion vanished instantly.
They named her Claire Winchester-Novak.
Cas became even more attentive with a little girl pup. He would sit in the rocking chair for hours, Claire tucked securely against him, his blue eyes never leaving her face. He seemed fascinated by the softness of her skin, the tiny, perfect curve of her ears, and her soft blond head.
For Dean, Claire was the missing piece he hadn't even realized he was searching for. Having her in his arms felt like a divine reward.
With his second newborn, Dean moved with an effortless grace. He navigated nursing, diaper changes, and Jack’s toddler energy with a calm that radiated throughout the house. The rage of the first time was gone, replaced by a tenderness.
He loved dressing her in the tiny outfits Sam had skeptically helped him pick out, showing her off to John with a proud, beaming smile.
Jack, not even a year and a half, was fascinated by the new pup. Cas was careful to involve him, teaching Jack how to be a gentle older brother.
"She is small, Jack," Castiel said, guiding the boy’s hand to gently pat Claire’s blanket. "And very lucky to have a big brother to protect her."
It pulled Dean right back to his own childhood, to the unstable life he’d shared with his little brother. While Sam was thriving out at Stanford, life felt entirely too empty without him. Dean counted down the days to any break that might bring Sam back for a visit; his brother couldn't return home soon enough.
“Unca Sammy?”
The promise of a visit coupled with a knock at the front door had two-year-old Jack’s little ears perked up, ignoring the holiday music softly playing in the background. The howling December wind curled in the moment Cas opened the front door. “Sammy," he whispered.
Dean looked up from the couch, where he was gently adjusting a swaddle around a sleeping Claire against his shoulder. His face instantly lit up, a brilliant, tired-but-happy grin. Sure enough, his little brother stepped through the door way. "Yeah, kiddo. That's Uncle Sam."
Before Dean could even finish his sentence, the toddler scrambled to his feet, his chubby legs moving as fast as they could carry him toward the front door, his winter socks sliding slightly on the hardwood.
"Whoa, hold on!" Cas intercepted Jack just before the boy could hurl himself into Sam’s legs, scooping him up into a secure hold. Cas looked a little rumpled, having just come home early from the dealership to beat the evening snow, but his blue eyes were warm. "Let your uncle actually get out of the cold first."
Dean carefully shifted Claire into one arm, standing up and walking over to join his mate and son at the door.
Sam looked a little less like a scruffy garage kid and a little more like a Stanford university student now, softer clothes, a laptop bag slung over one shoulder, and a thick scarf wrapped around his neck, but as soon as he saw his family, that familiar, dimpled Winchester smile broke across his face.
"Sammy!" Jack shrieked from Cas’s arms, kicking his legs in joy.
Sam laughed. "Hey! Look how big you got!"
Cas set Jack down, and the toddler practically launched himself at Sam’s snow-dusted shins. Sam dropped to his knees, ignoring the cold dampness on his jeans, and caught the little boy in a massive hug. Jack immediately buried his face in Sam’s hair, giggling maniacally as Sam lifted him up, spinning him around in the entryway.
"Did you miss me, Jack?" Sam asked, his breath still a little smoky from the cold.
"Missed 'ou! Look, Sammy, look!" Jack pointed wildly toward the living room, incoherent in his excitement to show his uncle the Christmas tree and every single toy he owned.
"I see the tree, buddy. We're going to play with all of it," Sam promised, setting Jack down but keeping a hand on his back. Sam stood up, his eyes immediately locking onto Dean.
Dean didn't say anything at first. He just stepped forward, wrapping his free arm tightly around his little brother’s neck, pulling him into a scent-heavy embrace. The familiar, comforting scent of Sam eased a tension in Dean’s chest he hadn't even realized he was holding.
"Missed you, kiddo," Dean murmured, squeezing him tight against the chill. "Stanford treating you okay?"
"It's great, Dean. But it's good to be home for the holidays," Sam replied softly. He pulled back, his eyes dropping to the tiny bundle in Dean’s arm. "Oh, wow."
"Yeah. Meet your niece," Dean said, his voice softening. He angled Claire so Sam could see her. She had a tuft of blonde hair and was currently frowning in her sleep, a textbook Winchester expression.
"She's beautiful, Dean," Sam whispered, reaching out a hesitant finger to touch her tiny hand. Claire's reflex kicked in, her miniature fingers curling tightly around Sam’s thumb. Sam’s eyes went shiny, a soft laugh escaping him.
"Welcome back, Sam," Cas said, stepping up and clapping a hand on Sam’s shoulder. "The house has been far too quiet without Jack having his favorite uncle to terrorize."
"Unca Sam! Look!" Jack was already back, dragging a giant plastic dinosaur by its tail, practically beside himself with the need for Sam's undivided attention.
"Alright, alright, Uncle Sam just got off a long, icy drive," Dean chuckled, though he nudged Sam toward the couch near the roaring fire. "Go on, college boy. Sit down and warm up before the kid bursts a blood vessel."
Sam happily let himself be led to the living room, collapsing onto the couch. Jack scrambled up burying himself into Sam's lap like a barnacle.
Dean watched them from the kitchen doorway, leaning back against Cas’s chest. Cas wrapped his arms around Dean’s waist, resting his chin on Dean’s shoulder, letting his Alpha pheromones wrap around his mate in a soothing wave that competed with the warmth of the hearth.
"Happy?" Cas murmured into the crook of Dean's neck.
Dean smiled, watching Sam patiently roar like a dinosaur to make Jack laugh, while John’s truck pulled into the snowy driveway outside, signaling the whole family was finally under one roof.
"Yeah," Dean breathed, placing a hand over Cas's arms. "Perfect."
Claire proved to be a firecracker from her very first breath. Fierce, loud, and energetic. While she brought an immense joy to their family, she also pushed Dean to the brink of his physical limits.
Within a few months, Dean found himself stretched dangerously thin. Claire was an insatiable nurser, constantly latched to his chest and draining his sanity, while Jack was at the peak of his chaotic toddler years, requiring constant supervision as he rambled around the living room. Dean’s days became a blur of spit-up, diaper changes, and the exhausting demands of two under two.
More than anything, Dean felt a profound sense of displacement. He loved his pups with every fiber of his being, but he found himself desperately missing the garage. He missed being Dean the mechanic, a stark contrast to the domestic, milk-heavy omega confined to the nursery.
Cas remained deeply attuned to the subtle shifts in Dean’s scent, recognizing the exact moments when the heavy toll of parenting two under two began to wear his mate down m. He didn't wait to be asked. Whenever he walked through the door after a long shift at Winchester-Novak Automotive, Cas immediately stepped up, swooping in to gather a rambunctious Jack for a bath or pacing the hallway with a fussy Claire tucked securely against his broad shoulder. His presence became Dean's daily lifeline, giving the Omega the breathing room he so desperately needed.
Just as he had with Jack, Cas gently took the initiative to encourage weaning.
"Come on, sweet girl," Dean coaxed, but his daughter’s mouth was clamped tight against the incoming spoon. "Just two more bites. For Daddy. Please? Don't make me bring out the airplane noises, Claire. We both know I'm terrible at them."
Claire blew a wet bubble, effectively spraying a green speck of pea puree onto Dean’s cheek.
Dean closed his eyes with a sigh. He didn't even have the energy to wipe it off.
A few feet away Jack sat victorious over a precarious block tower.
"Look, Papa!"
Castiel sat beside him, posture entirely devoted to the toddler beside him. “I am looking, Jack. It is an exceptionally good tower."
Jack beamed, seriously patting the top block. "For my trucks to be safe from the monsters."
"A wise strategy.” A smile tugged at the corners of Cas’s mouth.
From her high chair, Claire’s kicking stopped. Her big green eyes locked onto the sound of Cas’s voice. Dean watched as his ten-month-old pup bounced once, twice, urgent with importance.
"Pa-pa!"
Cas turned his head over his shoulder. His blue eyes were wide with surprise.
"Papa! Papa, Papa!"
"She said Papa!" Jack erupted, leaping to his feet and clapping with glee. He began to dance around Cas in a circle, his little bare feet thumping against the rug.
For a fleeting second, Dean felt a little pang of disappointment. He was the one who spent all day wiping away tears, the one who nursed them, the one whose body had been forever changed to bring them into the world. Yet both pups had ended up saying Papa first. Sometimes Dean felt like he was just the tired shore the waves crashed against.
But before the thought could curdle into a real pout, Claire reached out, her sticky fingers patting Dean’s arm.
"Da-da," she babbled, an imperfect attempt at the title they had been practicing, her eyes bright and adoring. "Dada-da."
Dean laughed, unbuckling Claire to lift his messy baby into his arms. "Yeah, baby. That's me. I've got you."
Cas cast him a wry smile, knowing just how happy Dean was by that one word. “And you thought she wasn’t going to say it.”
“Shh,” Dean grinned, bouncing the little girl. These little moments of parenthood made up for so much. “Don’t ruin the moment.”
Cas took over the bedtime routine that night. Tucking Jack in, making sure Dean was comfortable, and patiently rocking their daughter to sleep with a bottle of formula. Claire had been more willing to be weaned than her brother had been, and they were able to successfully ease her off the breast within her first year, allowing Dean to finally find a healthy balance between his beloved role at home and his passion on the garage.
