Le'an rolled over and fell asleep, his little face pressed against the mattress, his mouth slightly open. Chen Hao was still squatting by the bed, his hand supporting his chin, his eyes fixed on him.

"This kid, did he really flip it over by himself just now?" he asked in a low voice.

Susan sat on the sofa, her legs feeling a little weak. Having just given birth not long ago, and seeing the baby go through all this, she was more exhausted than anyone else. "You've already watched the replay three times, and you're still asking?"

"I just want to hear it again," Chen Hao grinned. "Isn't my son awesome?"

Carl closed his notebook, the pen cap clicking shut. "The movement was 86% complete, with the main deviation being in the arm support angle. Further upper body strength training is recommended."

"He's been working for less than a month!" Chen Hao exclaimed, his eyes wide. "You're making him do push-ups?"

“I’m just recording the facts.” Carl put his notebook into his coat pocket. “The developmental data is 12.3 percent above the average of the same period’s models, which is definitely something to celebrate.”

Nana's screen lit up, and a reminder popped up automatically: "The baby has achieved three milestone events in a row. The system suggests marking it as a 'highlight day'."

Chen Hao suddenly stood up, almost hitting the ceiling. "Yeah! What's the point of just the few of us knowing about something this big? We need to call someone over to check it out!"

Susan looked up: "You want to throw a party right now?"

"Why not?" Chen Hao paced back and forth. "He doesn't turn over every day. It would be such a waste to miss it. Let's get it done this afternoon, make something simple to eat, and Mom, Dad, Lao Li, and Xiao Wang can all come."

“He’s the one who needs rest,” Susan said, pointing to the child on the bed.

"Then let him lie there," Chen Hao said, shrugging. "Everyone can see that he can just say a few words, but no one should touch him. Besides, he's the family's number one hero now, shouldn't we throw him a celebration party?"

Susan didn't say anything, but the corners of her mouth curled up slightly.

Nana immediately brought up the schedule interface. "Suggested time: 3 pm to 5 pm, avoiding the nighttime activity period. The current ambient temperature is suitable and the air quality meets the standards, so a semi-open reception mode can be activated."

"You're doing a pretty professional job," Chen Hao said, leaning closer to look at the screen.

"The guest list, draft menu, and circulation plan have been generated," Nana continued. "It is recommended to set up an infant observation area on the east side of the living room, with soft mats laid out, and to limit the number of people approaching it."

"Okay, I'll do as you say." Chen Hao made the decision. "Then I'll make the call."

Susan leaned back on the sofa, watching him frantically flip through his contacts, and sighed softly. She looked down at the sleeping Le'an and reached out to straighten his little head, which had been turned over.

“If your dad comes, he’ll definitely want to hug you again,” she said.

“Don’t let me hold him.” Chen Hao walked over with his phone in hand. “Just say the doctor advised that newborns shouldn’t be held by just anyone. No one can convince you otherwise.”

"Will he believe that?"

"You have to believe it whether you want to or not." Chen Hao plopped down. "I'm a father now, I have to set rules."

Susan smiled but didn't reply.

For the next two hours, the house was like a wound-up toy. Carl silently picked up the cleaning robot, adjusted the speed and suction power, and vacuumed the carpet three times. He also checked the safety covers on all the sockets and put anti-collision strips on the corners of the coffee table.

Nana printed out a "Visitor Guidelines" and posted it on the door:

1. Wash and disinfect hands before entering.

2. No loud noises allowed.

3. Do not forcibly hold the baby.

4. Do not use flash when taking photos.

Chen Hao was in charge of cooking. He found half a chicken, two cabbages, and a bag of frozen dumplings in the refrigerator. He made chicken soup, stir-fried some greens, and fried a few eggs, arranging them in a smiley face shape.

"Is this considered a feast?" Susan carried Le'an, who had changed her clothes, out of the bedroom.

"It's all about the sentiment," Chen Hao said proudly. "Look at these eggs, don't they look like a family of three?"

"It looks like three suns to me."

"You don't understand art."

At ten minutes to three, the doorbell rang. Chen Hao quickly wiped his hands and went to open the door. His father was standing outside with a basket of eggs.

"I heard your grandson turned over in bed today?" the old man asked as soon as he entered the door.

“That’s right.” Chen Hao stopped him from rushing inside. “Wash your hands first, and read the rules.”

The old man glanced at the notice at the door, read it aloud, and snorted, "It's like a laboratory."

"Scientific parenting," Chen Hao said sternly. "If you violate the rules, we'll have to ask you to leave."

"Get out, get out, get out." The old man waved his hand and walked towards the living room. He immediately slowed his pace when he saw Susan on the sofa and the child in her arms.

Then people arrived one after another. Old Li brought a can of milk powder, Xiao Wang brought a pack of diapers, and someone else brought a little cotton-padded jacket. Everyone sat around the sofa, speaking in hushed tones, their eyes all fixed on Le'an.

"Looks like you," someone said with a smile.

“No way, he looks just like my mom,” Chen Hao blurted out.

“How could someone like your mother look like this?” Susan glanced at him.

Everyone burst into laughter.

Nana quietly turned on the projector, and a video appeared on the wall. In the video, Chen Hao was making faces at Le An, sticking out his tongue and rolling his eyes. The next second, Le An raised his leg and kicked him hard in the face.

The laughter erupted.

"This is a real-life recording of my own father being kicked." Chen Hao covered his face. "I've brought this humiliation upon myself."

“You deserve it,” Susan laughed.

Carl took a stack of papers out of his bag and handed one to each person. "This is my growth log, which includes smile trigger time, vocal frequency analysis, and a rolling over mechanics model."

The entire room fell silent for two seconds.

"You even remembered this?" Old Li flipped through the paper. "You even drew a diagram?"

“The data doesn’t lie.” Carl pushed up his glasses. “For example, here, the leg movement sequence shows that his left leg moved first, which suggests a possible dominant side tendency.”

"He's only been a month old!" Chen Hao shouted. "Don't commit to him for life!"

"I'm just offering this as a reference."

Susan held Le'an in her arms. He didn't cry even though he was surrounded by people. Instead, he opened his eyes wide and looked around as if he was recognizing people. She gently patted his back and heard someone say, "This child has such bright eyes."

Around five o'clock, Le'an started twisting her body and humming a few times.

"I must be hungry." Susan stood up.

"Oh, stay a little longer," Chen Hao's dad said, reluctant to leave. "Let me carry you for a bit."

"No way." Chen Hao stepped in front of him. "He's emotionally unstable right now. Hugging him will only make him more agitated."

"Just for a moment."

Not even once.

The two remained locked in a stalemate when Le'an suddenly burst into tears.

The scene fell silent instantly.

Susan quickly sat back on the sofa to breastfeed, and Chen Hao immediately turned off the music and drew the curtains halfway. Carl silently closed his laptop, and Nana turned down the brightness of the lights.

Only soft sobbing and the sound of a child swallowing remained in the room.

A few minutes later, Le'an finished eating, let out a small burp, and his eyelids slowly drooped down.

Chen Hao's father stood still, his hand still hanging in mid-air, not daring to move.

"Maybe next time," Susan said softly.

The old man nodded, turned and walked out, his back looking somewhat lonely.

After the last person left, the door closed. Only the four of them remained in the living room.

Gift boxes were scattered on the carpet, and used paper cups were piled on the coffee table. Nana began clearing the data, and a line of text popped up on the screen: [Today's total visitors: 11; blessings: 47; infant's emotional rating: A-]

Carl sat in the corner, his notebook spread out on his lap, having finished writing the last line.

Chen Hao sat cross-legged beside the crib, looking at the sleeping Le'an.

"He was really busy today," he said.

Susan leaned on his shoulder, her eyes closed. "But we are the happiest."

Nana's indicator light blinked slowly. Karl closed his notebook and looked up at the child in the bed.

Le'an's little hand suddenly moved, grabbing the strip of cloth on the bed railing and holding it tightly.
