Haikyuu Age Regression One-Shots

Lazy Days

Caregiver: Yamaguchi
Little: Tsukishima

Tsukki woke up and stretched to the best of his ability, finding it a little troublesome due to him being wrapped up in a bundle of blankets. He yawned and struggled to get out of the mess of blankets he was in, giggling when he was successful. He found Deeno, his stuffed dinosaur, and went to search for Yamaguchi. As soon as he opened the door and stepped into the hallway, he smelled pancakes and scurried to the kitchen. He saw Yamaguchi putting whipped cream on a stack of pancakes and Tsukki's eyes lit up as he ran to him.

"'Amaguchiiiiiiii!" the little yelled out as he wrapped his arms around the captain. Yamaguchi smiled and wrapped one arm around Tsukishima and kissed his head.

"Good morning my little Dino." Yams pat Deeno's head. "You too, Deeno." Tsukki giggled and stayed burrowed into Yamaguchi's side until he grabbed the plates and started walking to the table. Tsukki sat down next to Yamaguchi and grabbed his fork, smiling down at the strawberry pancakes.

"Go ahead and eat, bub. I already cut them up for you." Tsukki smiled and put the utensil down, grabbing the pancakes with his hands and shoving them in his mouth (me too tsukki, me too).

"It's guds, 'ama!" Yamaguchi smiled and started to eat his pancakes that had significantly much less  syrup and whipped cream on them. They both finished in no time and Yamaguchi grabbed a wet wipe to clean off Tsukki's face and hands.

"Are you full, baby?" Tsukki nodded and shot up from his chair, thanking Yams for the food and grabbing Deeno during his retreat back upstairs.

He got into the bedroom and immediately crawled into the "little space" that Tadashi made for him when he sleeps to Yamaguchi's house. It was an entire corner of Yamaguchi's room that had stuffies, blankets, and all of Tsukki's comfort items and was close enough to the bed for Yamaguchi to reach anything Kei needed without getting out of bed, which usually happened in the wee hours of the night.

Kei took his glasses off and buried himself in the pile of soft textures, closing his eyes. Tadashi walked quietly up the stairs and peeked inside of his room, smiling when he saw Tsukki's nose poking out of the pile of stuffies and his slow breathing.

"Good, he's sleeping again" Tadashi said as he went back downstairs to clean the kitchen. He was putting away the last plate when he heard Tsukki's whimpers come from the room. He quickly put away the plate and jogged upstairs. One side of the blonde's face was red, irritated from how he was sleeping, and he was rubbing his eyes. He locked eyes with Yamaguchi and whined again, reaching for him.

"Daddy." Tsukki whimpered out. Tadashi cooed and sat down in Tsukki's corner, pulling him into his lap.

"Someone woke up very small after their nap." Tsukishima was curled up in Tadashi's lap, his hand clutching his shirt tightly. Yams looked at the little one with concern. "Angel, are you okay?" Tsukishima yawned and buried his head in the crook of Tadashi's neck, rubbing his eyes in an attempt to wake himself up. He sat up after a while and poked Yamaguchi's face.

"C-Can we gos watch a movie pleaseeeee?" Tadashi chuckled and helped Tsukki stand up.

"Come on then. Your pick." Tsukishima squealed and ran ahead of Yamaguchi, sliding into the living room to pick out a movie. He settled on The Good Dinosaur, claiming that Jurassic Park is "too scawy fowr mes" as Yamaguchi pressed play on the movie.

The little one was immediately engrossed in the movie and didn't even notice when his daddy left the room and came back with popcorn and a sippy cup of strawberry milk. He subconsciously grabbed the sippy cup, refusing to take his eyes off of the television. Yamaguchi grinned and wrapped his arm around his little, his smile widening when little Tsukki snuggled into him.

They watched the movie in a comfortable silence, the only sounds being the crunching of popcorn, Tsukki sucking on his sippy cup, and the movie itself. When it ended, Tsukishima was just as starstruck as he was the first 80 times he watched the movie.

"Wow! That was a weally good movie daddy!" Yamaguchi shook his head with a smile and pulled him in closer. Kei's head found Tadashi's chest and he sighed as he heard his slow and strong heartbeat. "I loves you daddy." Tadashi's heart swelled and his grip around the middle blocker tightened.

"I loves you more, my little dino."
