The soft glow of candlelight filled the cozy Black-Potter living room, casting flickering shadows along the walls. Outside, snowflakes drifted down like bits of silver confetti, frosting the windows in delicate lace patterns. Y/N sat curled up on the couch, one hand resting on the small but unmistakable curve of her stomach. Across from her, Regulus paced with the anxiety of a man who once battled dark forces but now faced something infinitely more daunting: telling Harry he was going to have a sibling.
"You're going to wear a hole in the rug," Y/N murmured, a smile tugging at her lips.
"I'm trying to figure out the right words," Regulus said, stopping mid-stride. He ran a hand through his hair, his brow furrowed. "How do you tell a six-year-old that everything is about to change?"
Y/N patted the cushion beside her. "We tell him with love. And honesty." She tilted her head toward the staircase. "He's probably still awake, you know."
Regulus sighed, resigned, and climbed the stairs. Moments later, he returned, Harry perched sleepily on his hip. The boy's messy black hair stuck out at odd angles, his green eyes blinking in the dim light.
"Mama? Baba?" Harry rubbed his eyes. "Why am I awake?"
Regulus settled Harry between them on the couch. Y/N shifted to face him fully, brushing his hair back fondly.
"We have something important to tell you," she began.
Harry's eyes widened. "Is it bad?"
"No, sweetheart," Y/N said softly. "It's something wonderful." She exchanged a glance with Regulus before taking a breath. "You're going to be a big brother."
Harry froze. He looked from Y/N's belly to Regulus, and then back again. "A brother?"
"Or a sister," Regulus said. "We don't know yet."
Harry's mouth formed a small "o." Silence stretched between them like a fragile thread.
"Are you excited?" Y/N asked, her voice gentle.
Harry's legs swung against the couch. "I dunno. Will you still have time for me?"
Y/N's heart cracked at the uncertainty in his voice. She pulled him into her arms, cradling him tightly. "Oh, my love. There is nothing and no one that could ever replace you. You made us parents. And we will always have time for you. Always."
Harry sniffled into her shoulder. "Promise?"
"I swear it," Y/N said.
Regulus leaned in and kissed the crown of Harry's head. "You'll never be alone, Harry. You'll have us. And you'll have a little brother or sister to protect, to teach...maybe even to prank if you inherit any of your Uncle Sirius's tendencies."
That earned a watery giggle. Harry looked up. "I get to teach them stuff?"
"Absolutely," Y/N said with a smile. "Like how to fly a broom and sneak extra biscuits from the kitchen when Baba isn't looking."
"Oi!" Regulus shot her a look of mock disapproval, but his eyes were warm.
Harry's grin grew. "Okay," he whispered. "I think being a big brother sounds kinda cool."
Y/N pressed a kiss to his forehead. "You're going to be the best big brother ever, sweetheart."
That night, after Harry had fallen asleep between them, one hand resting protectively on Y/N's belly, Regulus whispered into the darkness, "He's going to be okay. We're going to be okay."
Y/N laced her fingers with his. "We already are."

The sun was barely peeking over the horizon when six-year-old Harry Potter-Black was woken up by the sound of soft footsteps. His wild hair stuck up in every direction as he rubbed his eyes and squinted at the doorway of his bedroom.
His Baba stood there, hair disheveled, an uncharacteristically wide grin on his usually serious face.
"Harry," Regulus whispered, voice thick with emotion. "She's here. Your sister's here."
Harry didn't need any more convincing. He scrambled out of bed, heart racing with excitement. "She's really here?" he asked breathlessly.
Regulus held out his hand, and Harry grabbed it tightly as they padded down the hall toward the master bedroom. The door was slightly ajar, and Harry peeked in.
His Mama was propped up against pillows, hair damp and face glowing with a tired but radiant smile. In her arms was a tiny bundle wrapped in a soft, moon-patterned blanket.
"Hi, sweetheart," Y/N whispered as Harry hesitated in the doorway. "Come meet your sister."
Harry crept forward, eyes wide. "She's so small," he breathed, standing on his tiptoes to see better.
"Would you like to hold her?" Y/N asked softly.
Harry's green eyes shot up to hers. "Can I?"
Y/N nodded, shifting slightly as Regulus moved to sit beside her, guiding Harry into the safe space between them. With infinite care, they helped him cradle the tiny baby.
"This is Danica," Y/N said, brushing a gentle finger along the baby's soft cheek. "Danica Potter-Black."
"Danny," Harry whispered, staring at the delicate face. "Hi, Danny. I'm your big brother. I'm gonna take care of you forever."
Danica gave a tiny sigh, her tiny fingers curling into a fist. Harry's heart melted.
"She's like a morning star," he whispered.
Regulus wrapped an arm around his son. "That's exactly what her name means, Harry. Morning star."
Harry beamed. "I love her already."
Y/N felt her heart squeeze with happiness as she met Regulus's gaze over their children's heads. At that moment, their little family felt complete.
