As expected of Yukino Yukinoshita, her ability to learn was absurdly strong.
She had clearly not even known how to hold a baby just moments ago, yet by the second time she held her, her posture was already quite standard.
"We can't keep spoiling her like this," Dong Yunshan sighed. "I still have to go home and make formula for her."
"Then what are you standing there for?" Yukino Yukinoshita shot him a sidelong look. "Go get a taxi."
Dong Yunshan: "...?"
P.S. Thanks to [-Tsukasa Ayatsuji-] for the tip!
Final Exams, Spring Break: Entering the House
"Welcome aboard, may I ask..." After helping put the stroller into the trunk, the driver returned to his seat and finally had time to take a careful look at the two people sitting in the back... three passengers in total, including the baby.
When he saw Dong Yunshan and noticed the obvious signs of training on his arms, the driver gave a polite smile.
Youth really was wonderful!
To have the courage and energy to put yourself through that.
Thinking back, the driver had once burned with passion and wanted to train himself into having a strong body too, only for life to press him down into this car.
His gaze shifted, and the driver saw the woman holding the baby... no, wait.
She was way too young!
When the driver looked back at Dong Yunshan again, his eyes were already filled with unconcealed condemnation.
"Say the address." Yukino Yukinoshita glanced at the driver, then urged Dong Yunshan, "Your sister seems hungry."
After Dong Yunshan gave the address, the apologetic-looking driver immediately focused on driving.
The car moved at an even speed. Dong Yunxi yawned and closed her eyes.
She seemed even cuter asleep...
The tiny hand clutching Yukino Yukinoshita's hair relaxed little by little.
Dong Yunshan reached out and opened his mouth, silently mouthing, "I'll hold her."
But Yukino Yukinoshita did not look at him at all.
Dong Yunshan lightly touched Yukino Yukinoshita's arm with his own. The moment Yukino Yukinoshita noticed him, Dong Yunxi also felt the small movement and opened her eyes.
The hand that had already loosened once again grabbed Yukino Yukinoshita's hair.
This was definitely Dong Yunshan's biological sister...
Under Dong Yunxi's gaze, Yukino Yukinoshita kept smiling, her cold eyes narrowing as they fixed on Dong Yunshan.
The meaning was obvious.
Look what you've done.
It was even scarier than her usual expressionless face.
As expected of the genius beautiful girl Yukino Yukinoshita, she had actually discovered so quickly a method that would not scare Dong Yunxi, but could warn Dong Yunshan.
Dong Yunshan behaved himself.
After all, his sister was in her hands.
When they reached their destination, Dong Yunshan opened the door, and only after Yukino Yukinoshita carried the child inside did he bring in the stroller along with a whole pile of things.
Yukino Yukinoshita swept a glance over the living room. Most of it was very tidy; only the area near the sofa had a conspicuous pile of baby supplies stacked up.
Without Dong Yunshan bothering her, Baby Xi slept very soundly in Yukino Yukinoshita's arms. Even the walking around just now had not woken her.
Yukino Yukinoshita carefully placed Dong Yunxi on the sofa, confirmed that she had not startled awake, let out a long breath, and sat down on the sofa on the other side, panting slightly.
Although her thighs had taken on part of the weight while they were in the car, her hands still could not relax.
With Yukino Yukinoshita's stamina, being able to hold out until now was already extremely difficult.
Dong Yunshan walked toward the fridge. "Want something to dr—"
He had only gotten halfway through the sentence when Yukino Yukinoshita glared at him fiercely.
What now?
Yukino Yukinoshita only glared at Dong Yunshan once, then turned her head to look at Dong Yunxi.
So she was afraid of waking the baby.
"It's fine. Once she's asleep, noise won't bother her." Dong Yunshan walked over, placed a cylindrical bolster beside Dong Yunxi, and gently pushed the baby's back with his hand. Baby Xi turned onto her side and hugged the bolster, her chubby leg naturally draping over it. "I worried about that before too."
She really did not wake up... Yukino Yukinoshita asked curiously, "How did you find out?"
"Simple." Dong Yunshan casually took a palm-sized drool towel and covered Baby Xi with it. "Ah, ah, ah, ah..."
He raised his volume bit by bit, and the moment Dong Yunxi's little arm clearly twitched, he immediately stopped getting louder and returned to a normal speaking volume. "Practice 104 is the only way 278 to true knowledge."
Yukino Yukinoshita: "...Do you have black tea?"
"No black tea. I have iced Coke."
"No."
"Mm..." Dong Yunshan thought for a moment. "Should I make you some formula?"
Yukino Yukinoshita: "...?"
"I'll add some strawberries too, toss in some ice..." Dong Yunshan's voice grew weaker and weaker, because Yukino Yukinoshita's gaze was turning increasingly murderous.
Yukino Yukinoshita: "Water."
"Coming right up." Dong Yunshan poured Yukino Yukinoshita a glass of water.
After drinking the glass of water, Yukino Yukinoshita finally recovered a little. Out of the corner of her eye, she noticed the open notebook on the coffee table and picked it up casually.
Baby Xi Manual
It seemed to have been written by Dong Yunshan's mother.
And she had actually called it that.
If it were her own family...
"Thanks for helping out today." Dong Yunshan set the washed fruit on the coffee table. "Have some fruit first to tide you over. You haven't eaten yet, right? What do you want? I'll make it for you."
"No need." Yukino Yukinoshita shook her head. "I'll rest a little and then leave."
If Dong Yunshan had not made her angry just now, she would already have finished resting by now.
"All right, then." Dong Yunshan knew Yukino Yukinoshita was not the sort of person who easily changed her mind. If she said she would not eat here, then nothing he said would be useful. If he tried to keep her with something like "you're already here anyway," it would have the opposite effect. "Then I'll make some formula for Xixi first. She'll probably wake up hungry in a bit."
Dong Yunshan boiled the water, then started sorting through the things they had bought.
Yukino Yukinoshita ate fruit as she sat on the sofa, sometimes looking at the busy Dong Yunshan, sometimes looking at the sleeping Dong Yunxi.
It did not take long for Dong Yunshan to sort all the various things they would need into categories, and the boiled water had also cooled down.
Yukino Yukinoshita nodded lightly. Putting everything else aside, once Dong Yunshan got moving, he was still very reliable.
With so many things, if she had been the one tidying them up, she would have needed to rest several times in between at the very least.
Dong Yunshan washed his hands, checked the Baby Xi Manual, found the corresponding can of formula, took a bottle from the sterilizer, and scooped two spoonfuls of formula powder into it.
Yukino Yukinoshita frowned. "Wait!"
"Hm?" Dong Yunshan froze.
"Water first." Yukino Yukinoshita sighed. "If you put the formula in first, it clumps easily and affects the baby's absorption. The amount of water is also harder to control, which affects the mixing ratio."
"So there's that too..." Dong Yunshan pointed at the bottle. "Then what do I do with this?"
"Pour it into a bowl and drink it yourself later. You can add some ice and strawberries." Yukino Yukinoshita gave him an annoyed glance. "Also, when you scoop formula, you need to level off any powder above the edge of the scoop."
"The measuring scoop that comes with the formula can is a standard measure. Generally, the standard is for the formula to be level with the top edge of the scoop." Yukino Yukinoshita got up and walked over to Dong Yunshan. "As for the ratio, it's on the formula can... here. Too little water makes it thick and hard to digest. Too much water means insufficient nutrition. You have to follow the ratio strictly."
"Got it." Dong Yunshan poured the appropriate amount of water into the bottle, added the formula, and after Yukino Yukinoshita nodded lightly, screwed on the lid and shook it hard to mix it evenly.
"You..." Yukino Yukinoshita pressed a hand to her forehead as if she had a headache. "You can't shake it."
Dong Yunshan: "Huh?"
Yukino Yukinoshita snatched the bottle from Dong Yunshan's hand and pointed at the obvious bubbles inside. "So many bubbles will make the baby swallow too much air, causing spit-up and bloating—do you shake your cola before drinking it?"
"No..." Dong Yunshan obediently took the scolding.
"You drink this bottle yourself." Yukino Yukinoshita handed the bottle back to Dong Yunshan. "If you want no bubbles, you need to... Don't drink it!"
"Huh?" Dong Yunshan had almost put the nipple in his mouth.
"Don't touch the baby's bottle nipple." Yukino Yukinoshita snatched the bottle back again. "Go get a bowl."
Dong Yunshan walked into the kitchen and came out with a bowl.
Yukino Yukinoshita poured the milk into the bowl, and a rich milky aroma immediately spread through the air.
Grrrgle~
Yukino Yukinoshita's stomach rumbled.
She had gone to the bookstore early to look at cat photo books, then held a little baby for a long time. Her already limited stamina had been badly drained, and the little bit of fruit just now had not made her feel full. Instead, it made Yukino Yukinoshita even hungrier.
"Stay for lunch before you go." Dong Yunshan chuckled softly. "I'm hungry too, just in time."
Yukino Yukinoshita was just about to refuse when she suddenly noticed something interesting.
After having the baby around, Dong Yunshan seemed especially obedient.
In the span of just a few sentences, she had already rejected Dong Yunshan three times, and Dong Yunshan had accepted all of them gladly.
Was this not exactly the kind of failure within Dong Yunshan's range of acceptance that she wanted?
Maybe... this was a good chance to correct him.
"All right." Yukino Yukinoshita nodded lightly. "Make the formula first."
Under Yukino Yukinoshita's watchful eye, Dong Yunshan first added the appropriate amount of water, then added the formula, screwed on the lid, and looked at Yukino Yukinoshita.
"Have you played with a bamboo dragonfly before?" Yukino Yukinoshita raised her hand and gestured. "Like playing with a bamboo dragonfly, clamp it between both hands and roll it, keeping the motion horizontal."
Dong Yunshan did as she said, and sure enough, there were not as many obvious bubbles as before. He looked at Yukino Yukinoshita in pleasant surprise.
"Why are you looking at me?" Yukino Yukinoshita rolled her eyes at him. "Waiting for me to praise you? Open the bottle and let the air out."
Dong Yunshan unscrewed the cap to vent it, then screwed it back on. Hearing movement from Dong Yunxi's side, probably because she had smelled the milk, baby Yunxi let out a muffled sound.
Dong Yunshan walked in quickly, picked up his little sister, and raised the bottle. "Come on, Xixi, cheers."
"Cheers, really..." Under Dong Yunxi's gaze, Yukino Yukinoshita stopped Dong Yunshan with a sweet smile. "I'll make you another bottle. The two of you can drink yourselves under the table."
Dong Yunshan was puzzled. "Didn't we already make one bottle?"
"You really want to clink bottles with her, don't you?" Afraid of scaring the baby, Yukino Yukinoshita couldn't glare at Dong Yunshan, so she could only secretly pinch him. "Test the temperature on your arm first."
"That's a thermostatic kettle..."
"You still have to check it." Yukino Yukinoshita applied more force with her hand. "What if you mess it up one day?"
Dong Yunshan squeezed a few drops onto his arm and felt that the temperature was just right.
Yukino Yukinoshita picked up the book they had bought, opened it, quickly found the relevant section, and guided him aloud. "Aim the nipple toward the baby's mouth. From the side close to the mother's... brother's body, gently move it from the corner of the baby's mouth to her lips. Touch the baby's lips with the nipple, and the baby will naturally latch on and start feeding."
Dong Yunshan followed Yukino Yukinoshita's instructions. "Like this?"
Yukino Yukinoshita's brows furrowed slightly.
This was exactly what she was worried about. If he failed repeatedly, a person would start to doubt himself, then become afraid to act, and even give up thinking, only knowing how to follow orders.
Luckily, baby Yunxi was very cooperative.
Before Yukino Yukinoshita could speak, Dong Yunxi had already latched onto the nipple.
"Looks like this is right." Dong Yunshan let out a relieved breath. "Help me feed her for a while. I'll go cook."
Yukino Yukinoshita took Dong Yunxi into her arms with practiced ease, and baby Yunxi, focused on eating, cooperated very well.
Holding Dong Yunxi as she sat on the sofa, Yukino Yukinoshita followed what she had just read in the book, holding the bottle at a certain angle so the milk completely filled the nipple, preventing the baby from swallowing too much air.
As expected of Dong Yunshan's little sister, her feeding speed was astonishingly fast.
Yukino Yukinoshita could clearly see the nipple flattening a little at a speed visible to the naked eye.
