"Are you hungry, baby?" Nini asked her adorable baby boy, Min Joong. He was seated in his high chair, nibbling on his own fingers. Nini giggled and ran her fingers through his silky dark hair. "I'll take that as a yes."

"Umma~" Jaehyuk's little voice filled Nini's ears and she whipped around to see him holding his sister's hand. Nini smiled warmly at them. "What's up, Jaehyukkie?" She kneeled down to match his height. "Umma, we want to help you with baby Min Joong," Jooyeon said for her brother. Nini looked up at Jooyeon. "Aww, you do? I'd love that. You guys can help feed Min Joong so I can clean up the kitchen a little bit."

Jooyeon and Jaehyuk nodded excitedly to the agreement, their eyes big and full of anticipation. Nini kissed their foreheads before retreating to the kitchen and grabbing Min Joong's meal of baby food with a little Mickey Mouse spoon. She returned to the dining table to see Jooyeon and Jaehyuk had already pulled up chairs on either side of their brother, ready to feed him. Nini couldn't help but let a bright smile appear on her face. She was more than happy that her babies were more than eager to take care of their little brother. Before she could take a step towards her children, she felt a pair of arms wrap around her waist from behind. "What's going on?" Jonghyun asked, indicating the babies. Nini turned in his arms and pecked his lips. "Yeonnie and Jaehyuk want to feed Min Joong while I clean up a little." Jonghyun smiled and look towards his babies again. "Do they really? I have to get pictures of this. I'll take the food to them, love." He kissed her cheek and took the food from her, heading over to his kids.

"Appa!" Jaehyuk said with a bright smile on his face. Jonghyun grinned and leaned down to kiss his forehead. "Appa, we're gonna feed Min Joong!" Jooyeon exclaimed, reaching for the baby food in her dad's hands. Jonghyun handed her the food and leaned down to kiss her forehead as well. "Yeah? Make sure to not feed him too much and let him swallow before you give him more." Jooyeon nodded  "Okay appa. We have to take good care of Min Joong. Right Jaehyukkie?" Jaehyuk smiled and clapped his hands. "Yeah!" Jonghyun pulled up a chair to watch over them as they fed his baby.

Nini couldn't help but stop her cleaning and lean against the counter to watch the adorable sight of Jooyeon taking a small amount of baby food on the spoon and telling Min Joong to open his mouth. Min Joong removed his fingers from his mouth and eyed the spoon with the food. He looked up at his noona and opened his mouth a bit. Jooyeon smiled and gently offered the spoon to him and Min Joong happily ate the food, bouncing in his high chair. Jooyeon and Jaehyuk giggled at their brother's reaction. "Again! Again!" Jaehyuk said, bouncing in unison with his brother. 

"You try it, Jaehyukkie!" Jaehyuk seemed unsure and looked towards his dad with big innocent eyes. Jonghyun grinned and nodded. "Go ahead, baby." Jaehyuk smiled brightly and took the food and spoon from Jooyeon. He dunked the spoon into the food and Jooyeon grabbed his wrist. "That's too much." She hit the spoon against the side of the small jar and got rid of a hunk of food. She handed the spoon back to her brother. "Tank you, noona!" He smiled at his sister and slowly approached his brother's mouth with the spoon. Min Joong seized his bouncing and opened his mouth to welcome the food. Jaehyuk had the brightest smile as his brother ate the food and continued his happy bouncing. 

Jonghyun was smiling just as big and capturing a video of his babies being absolutely adorable. Nini's heart squeezed when she noticed Jonghyun and Jaehyuk have identical smiles. She shook her head before she would burst into tears or something ridiculous like that and got back to cleaning up the kitchen. As she cleaned, she adored hearing the sounds of her huband's and babies' giggles. 

The kids finished feeding their brother not too long after and were extremely proud of themselves. "Look, umma! Jaehyukkie finished all of his food! He was really hungry." Nini giggled and took the empty jar and spoon from Jooyeon. "That's good. He needs to eat to grow nice and healthy." 

"Umma~" Nini's eyes looked up towards Jaehyuk who was still by his brother's side. "Stinky!" He said, waving his hand in front of his nose. Jonghyun chuckled at Jaehyuk's actions. "I think baby Min Joong needs a diaper change, love." 

"Ooh, can we help, umma?" Jooyeon asked, clasping her hands together and putting on her best pouty face. Nini ran her fingers through Jooyeon's hair and grinned. "How can I say no to you, Yeonnie?" Jooyeon giggled and hugged her mom's waist. "Thank you, umma~" Nini couldn't believe how tall she was already getting despite being only 3 years old. "Let me just go pick him up and meet you guys in his room." Jooyeon nodded and ran over to Jaehyuk, taking his hand. "Come on, let's help umma again!" The two babies ran off to Min Joong's room.

Jonghyun chuckled and picked Min Joong up and out of his high chair. "Do you want to teach them how to change a diaper?" Nini asked with a slight smirk. "Are you teasing me? Do you remember how hard it was for me to change Jooyeon's diaper for the first time?" Nini laughed and pecked his lips. "Min Joong is our 3rd child and you still can't do it?" Jonghyun shurgged and pouted. "There's so many flaps and turns and I can't keep up." NIni only laughed harder. "Come watch me show the kids, maybe then you'll get it." 

Jonghyun laughed along with her and followed her to Min Joong's bedroom where Jooyeon and Jaehyuk were sitting on the floor, playing hand games. They immediately stood up when their parents entered the room with excited smiles on their faces. Nini set Min Joong down on the bed and began to undress him out of his onesie. Jooyeon and Jaehyuk hopped onto the bed around him and watched their mom intently. Jonghyun stood to the side with his arms crossed, hoping he'd learn how to change a diaper. 

Nini began to slowly remove his diaper and explaining exactly what to do clearly. It was mostly for Jonghyun but she kept her eyes on her babies. They nodded to almost everything she said until she removed the diaper and started making little comments. "Umma, that smells!" Jooyeon plugged her nose and laughed. Jaehyuk hid his face in his hands and made little grossed out noises. Jonghyun laughed at his children along with Nini. "Come on, babies. Pay attention so you can help me next time." Jooyeon and Jaehyuk continued to plug their noses and watch their mom change their little brother. Jonghyun paid close attention in hopes he could be the one to change Min Joong next time.

Nini finished up and dressed Min Joong back in his onesie all nice and comfortable. Jooyeon and Jaehyuk clapped for their mom with big smiles on their faces. "Umma, does it always smell that bad?" Jooyeon asked. Jonghyun burst into laughter and ruffled her hair while Jaehyuk joined in, laughing for no reason. Nini giggled. "Not always it just-" Before Nini could even finish her sentence, MIn Joong began crying. 

Nini held him to her chest and began to bounce him lightly up and down while running her hand up and down his back. "Ssh, baby. Don't cry. It's okay. Umma's here," she cooed repeatedly but baby Min Joong would not calm down. "Is he okay, umma?" Jooyeon asked, holding Jaehyuk's hand tightly since he appeared a bit worried for his little brother. Nini nodded and continued to bounce him a bit. "He's probably just tired," she said, assuring her babies.

"Here, let me try to calm him," Jonghyun reached out to take Min Joong and Nini gently handed him over. Jonghyun held Min Joong and began to walk around the room, shushing Min Joong and trying to soothe him to sleep. He continued for a couple of minutes and he still would not calm down. Nini ran her fingers through her hair and sighed. It pained her that he was crying so hard and she had no idea what to do. She tried to use his binkie to calm him but he just spat it out of his mouth. Jonghyun and Nini exchanged worried looks. 

Jonghyun sat on the bed, his back up against the headboard, rocking his baby gently from side to side and still shushing him. Nini went to prepare a bottle of warm milk for him and quickly rely to find that Min Joong was still as upset as before. Jooyeon and Jaehyuk were worried and upset for their little brother, wondering why he was so sad and why he was crying so much. They wanted it to stop and hear his little laugh again. That's when Jooyeon got an idea. She smiled brightly and leaned in to whisper her idea to Jaehyuk. A smile crept onto his face and he nodded eagerly. 

"Umma, can we help?" Jooyeon asked, slightly yelling over Min Joong's wailing. "Oh baby, I don't know if there's anything we can do." Jooyeon pouted. "Can we try?" Nini sighed and ran her fingers through Yeonnie's hair. "Okay." Jooyeon nodded and crawled over next to her dad with Jaehyuk already on the other side of Jonghyun. Nini and Jonghyun were not expecting what came out of their babies' mouths.

Jooyeon began to hum to a particular song that made Nini's heart squeeze. Jaehyuk listened to his noona closely and began to hum along with her. Once Jooyeon felt that Jaehyuk had the right tone going, she began to sing to the best of her capability. She began to sing Remote Control; a song that she grew up listening to since her dad would sing it to her mom and her mom would sing it to her as a lullaby. She mumbled the words she didn't know but sang with such a smooth and adorable voice. Nini placed a hand over her heart as tears brimmed her eyes and Jonghyun was frozen, his heart swelling. 

Not too long after, once they hit the chorus, Min Joong began to quiet down, as if he was actually listening to his siblings sing to him. Jaehyuk kept up the humming and increased his volume as his brother quieted down. Jooyeon had a small smiling appearing on her face as she continued to sing in her adorable voice. Nini was on the verge of sobbing from the hidden talent her daughter had and from how touched she was that her babies were singing their brother to sleep. Her eyes shifted to Min Joong and he had stopped crying, his eyes moving from his noona to his hyung in wonder. 

And slowly but surely, Min Joong's eyes began to flutter close. Jooyeon's voice quieted down to a soothing tone and Jaehyuk's humming matched her voice. They kept singing and even started over the song until Min Joong's eyes closed for sure. Jonghyun could hear Min Joong's even breathing and he nodded towards the kids, signaling that he was asleep. He cautiously stood up and carried him to the crib, gently setting him down and placing a blanket over him. The rest of the Mouse family quietly eased their way out of the room and shut the door. Nini and Jonghyun waited until they were in the living room to shower their babies in kisses and thank them and tell them how talented they were. 

"Oh baby, that was so beautiful! Jaehyuk you were humming so cutely and matching with your noona! Where did you guys learn this?" Nini asked, kissing both of her babies everywhere around their faces. They were giggling like crazy and Jonghyun hugged them tight against his chest, kissing the top of their heads. Jooyeon shrugged at her mom's question. "Umma always sings it to us as a lullaby so I thought it would work for baby MIn Joong." Nini smiled so bright and kissed her babies once more.

Jonghyun smiled proudly. "You're both amazing with vocals at such a young age. I'm speechless. My babies are gonna be idols someday." Jooyeon and Jaehyuk giggled, smiling just as bright. "Like umma and appa!" Jaehyuk said, clapping his hands. Nini and Jonghyun exchanged wide smiles and a quick peck on the lips. Nini nodded."You're both gonna make us so proud someday. I love you both and baby Min Joong with all of my heart." Jonghyun joined the hug with his beautiful family and kissed each of their foreheads. "I can't wait to see you both on stage one day, performing your hearts out. Just like umma and appa."
