There was a time when Bi Bi suddenly developed a laziness towards eating. His mom reminded him:

Bi Bi, please eat!

Yes!

Bi Bi replied to his mother, took a spoonful of porridge, and then resumed playing. Mom, busy with other tasks, refrained from urging Bi Bi to finish his entire bowl of porridge.

Gradually, less and less food made its way into Bi Bi's stomach. Mom observed:

I've noticed fewer friends visiting lately, so I haven't been chewing much either.

The two teeth seldom worked, instead turning around to playfully tease each other, constantly knocking against one another. The throat expressed its distress:

I'm so sad.

Subsequently, the Throat swallowed air into the stomach, causing it to swell and become even emptier. The stomach, in its misery, constantly groaned:

Poor me. I'm starved!

As a result, the stomach involuntarily contracted, leading to boiling and the release of acidic substances. When the stomach walls pressed together, inundated with sour gastric juice, it cried out in pain:

That hurts! I'm so sorry!

The gallbladder, irritated, turned to the liver:

What's wrong? Why do you keep leaking fluid into my pocket? I'll eat you back now...

The gallbladder squeezed, causing bile to flow back into the liver, prompting the liver to suffer and cry out for help.

Meanwhile, Bi Bi continued without eating anything, merely drinking a glass of orange juice. Seeing a new substance flowing in, the mouth eagerly took a sip. The Throat also enthusiastically accepted it, pushing the orange juice down the Esophagus. The Esophagus, content, briefly stored the orange juice before moving it back to the stomach. The stomach, expanding to take in the orange juice, attempted a strong contraction, resulting in unexpected pain due to the mixture of orange juice and gastric juice. Unable to control it, the stomach squeezed forcefully, forcing everything to rush back up the Esophagus, through the Throat, and out of the mouth. Bi Bi groaned and complained of stomach pain.

Alarmed, Mom quickly took Bi Bi to the doctor. The doctor patted Bi Bi's stomach - "Pap... tap... tap... tap... tap...". After checking the mouth, throat, nose, and ears, finding nothing wrong, the doctor concluded:

Good! However, to be sure, let's conduct an ultrasound.

While undergoing the ultrasound examination, Bi Bi heard a small voice:

There's nothing wrong with the baby's stomach. If you eat regularly, your pain will subside.

Indeed, the ultrasound doctor confirmed on the form: "All organs are normal."

Bi Bi returned to the clinic, and the doctor advised:

You're not sick at all. It's just because of laziness, not eating enough vegetables, and not drinking enough water that you have stomach pain and vomiting. Ensure you eat regularly, consume plenty of fruits and vegetables, and stay hydrated!

Back home, Mom cooked porridge for Bi Bi. As soon as Bi Bi tasted the spoonful of porridge with cooked meat and vegetables, he eagerly devoured it:

So delicious... More...

The Throat urged:

Uncle Mouth, chew quickly and push it down for me!

The Esophagus and Stomach buzzed in anticipation of Bi Bi's porridge. After a few squeezes, the stomach processed the received porridge and urged:

Hurry up and give me a contraction. There's a lot of gastric juice being secreted!

The Liver and Gallbladder woke up, secreting bile to aid in digestion.

Mom reminded:

You haven't eaten much lately; now eat slowly. Rest, take a nap, and then eat again.

During the afternoon nap, Bi Bi experienced a sharp pain in his stomach and exclaimed:

That hurts!

Mom inquired:

Why are you screaming while sleeping?

Someone punched me in the stomach.

Mom listened to Bi Bi's belly and reassured:

You're probably just hungry. Go back to sleep and be good.

Upon waking up, Bi Bi had another meal.

In the afternoon, Bi Bi asked Grandma for food again. The girl marveled:

It's so fragrant; the fried fish is delicious.

During that meal, Bi Bi enjoyed rice, fish, beans, boiled cabbage... After finishing one bowl, he had another. He advised:

Eat slowly so the food can stay in your stomach; otherwise, it will come back out.

At night, Bi Bi drank milk again and inquired:

Why did you make me eat so much today?

Because the doctor advised me to make you eat heartily...

Mom patted Bi Bi's head and smiled gently:

So, do you trust the doctor more than your grandparents?

Bi Bi smiled awkwardly...
