Concerns about raising a baby aged 0-12 months

Is it normal to have an hour between feedings? Reasons why babies don't eat solid food

Worries about night crying and developmental delays










"I'm only going an hour between feedings... is this normal?"

"What's the devilish third week? Suddenly, he won't stop crying."

"My baby won't eat any baby food...I'm worried about nutritional deficiencies."


In front of my newborn child,

Every day brings new worries and questions.


Especially for first-time parents,

"I want to do something for this child, but I don't know what the right thing to do is."

"I have so much love, but I'm worried because I don't know how to express it."

You may often feel this way.



This guide is for moms who are searching for the right things in the middle of the night.

For over 200 specific concerns ,

The expertise of midwives, childcare workers, and nutritionists

Based on the real experiences of 2,000 senior mothers

"I see, that's the reason!"

We provide you with satisfaction and peace of mind.



When you finish reading, you will surely

"My upbringing wasn't wrong."

"There's more we can do for this child."

Your heart will be filled with a warm feeling.


Let's learn together for the sake of our beloved children.


Is it normal to have an hour between feedings?

Is it true that newborns need 18 hours of sleep?




"I just breastfed him, and he's already crying... is my breast milk not enough?"



Holding a newborn baby,

Many moms have this fear.


[Conclusion] A 1-hour gap between feedings is completely normal.


In fact, the "every three hours breastfeeding" that you often see in parenting books is

This is merely a guideline based on formula feeding .


Breast milk is easily digestible and leaves the stomach within 1-2 hours.

The baby will feel hungry again.

Furthermore, frequent breastfeeding plays an important role in promoting milk production.


Don't think, "Why is it so hard for me?"

Your and your baby's bodies are working hard,

It's proof that we are working together and growing .


Is it true that newborns need 18 hours of sleep a day? Is 12 hours a day okay for babies?



"The parenting book says 18 hours, but my child only sleeps 12 hours..."


The actual amount of sleep a newborn baby gets varies greatly from person to person .


[The reality of newborn baby sleep time]

・12 to 20 hours (varies greatly from person to person)

・Children who sleep well: 18 to 20 hours

・Normal child: 14 to 16 hours

・Children who don't sleep much: 12 to 14 hours


12 hours is no problem at all.


It's not the amount of sleep that matters,

This is what the baby looks like when awake.

If you're in a good mood and your weight is increasing steadily,

This means that your child is getting the best possible sleep .


There is even research that suggests that children who sleep less are more intelligent.

Your baby is probably a very curious child.


Why the baby suddenly won't stop crying in the third week

The Science of Twilight Crying




"When he was about three weeks old, he suddenly started crying in the evenings... what happened?"



The baby who had been relatively quiet until now

The "terrible third week" is when you suddenly start crying for no apparent reason.


This is evidence that your baby's brain is developing rapidly.


From about three weeks after birth, a baby's nervous system develops dramatically.

You will become more sensitive to stimuli from the outside world.

Unable to process the day's worth of stimulation,

Crying helps you process your emotions .


That means the baby is crying

"I learned a lot today."

This is a sign that...


It's not the mother's fault or the way she was raised.

Rather, it is evidence of steady growth .

Please watch over them warmly.


How long will the reversed day and night continue? The developmental schedule of the biological clock



"He wakes up every two hours in the middle of the night and sleeps soundly during the day... when will he finally be able to sleep through the morning?"


[The truth about the development of a baby's biological clock]


0-2 months: The body clock is not yet fully developed

A state in which the concept of "day and night reversal" does not exist


3-4 months: The body clock begins to function

The key period when melatonin secretion begins


4-6 months: Rhythm establishment

You'll be able to sleep 4-6 hours straight at night


In other words, it is normal for a baby's day and night cycle to be reversed until the age of three months .


There is no need to compare, "Why are other kids sleeping at night?"

Your baby learns at his own pace

Because it's growing steadily .


Is it too late if your baby doesn't roll over at 4 months?

The best time to start baby food




"My baby is already 4 months old and still can't roll over...is he developmentally delayed?"



When I see other babies tossing and turning,

You can't help but feel anxious when comparing them to your own child.


[Realistic data on when children can turn over]


・Complete at 4 months of age: Approximately 20%

・Complete at 5 months of age: Approximately 40%

・Complete at 6 months of age: Approximately 70%

・Complete at 8 months of age: Approximately 95%


In other words, 80% of babies are unable to roll over by the time they reach four months of age .


Even more surprising,

Rolling over is not a necessary developmental stage.

Many children start by sitting or crawling.


The important thing is not "when can we do it?"

"Is the child growing at his or her own pace?"

If you can show a new expression or reaction every day, even if it's just a little bit,

That is the best evidence of growth.


The best time to start baby food and new common knowledge about allergenic ingredients



"My baby is 5 months old now, so should I start solid food? But I feel like it's too early..."


When starting solid food , the most important thing is the baby's readiness rather than their age .


[A sure sign that it's OK to start]

✓ Neck is strong

✓ Able to sit for more than 5 seconds with support

✓ Sees food and reaches for it

✓ Significant increase in drooling


New common sense about allergenic ingredients:

From the traditional approach of "delay and prevent"

It has changed to "prevention by giving small amounts at the appropriate time ."


For example, eggs are produced from 5 to 6 months of age.

Starting with a teaspoon of hard-boiled egg yolk,

It has been shown to actually prevent allergies .


To protect the health of our beloved children,

Use the latest scientific knowledge.


11 reasons why your baby won't eat baby food

Measures to deal with sudden and severe shyness




"I made it with all my effort, but he won't eat a single bite... Am I making it wrong?"



When your baby refuses the baby food you've lovingly prepared,

It makes you feel as though your love has been rejected.


But don't worry, there's always a reason why they don't eat it.


[11 reasons why babies don't eat baby food]


1. I'm not hungry yet

Loss of appetite immediately after breastfeeding or on days when activity levels are low


2. The hardness of the ingredients is not right

Too hard or too soft for the baby's age


3. I hate spoons

The coldness of the metal and the size that doesn't fit in the mouth


4. Preferences due to developing taste buds

Suddenly, they may start to dislike foods they were eating yesterday.


5. Environmental Issues

TV noise, background noise, and bright lights


These are signs of normal baby development .

Your love is definitely felt.


My shyness has suddenly become intense! Is this normal?



"Until yesterday, she was smiling at everyone, but suddenly, she burst into tears just by seeing her dad..."


Intense shyness around 6 to 8 months of age

This is evidence that your baby's intelligence is developing dramatically .


[The scientific mechanism behind shyness]


✓ Improved facial recognition capabilities

"I've learned to distinguish between my mom and other people."


✓ Memory development

"I remember my mom's face every day."


✓ Formation of attachment relationships

The perception that "Mom is the person I feel most comfortable with"


In other words, shyness is

"Mom, you are the most important person to me."

It is an expression of love.


Even if Dad looks sad,

"This is a special time for you, Mom."

Let's keep a warm eye on them.


Is it abnormal for an 8-month-old not to crawl?

A solution to avoid having to do housework late




"He's already 8 months old and he's still not crawling...while other kids are already moving around easily."



When I see a child of the same age crawling in the park,

It makes your chest feel tight.


However, in reality, about 25% of babies do not crawl.


Top 5 Reasons for Not Crawling


1. Sitting too comfortably

An environment where toys are within reach while sitting


2. Standing up is more fun

A curious child who is attracted to higher perspectives


3. Choose another mode of transportation

Sitting shuffle, crawling, spinning, etc.


4. Cautious personality

A smart kid who checks for safety before taking action


5. Hypersensitivity in the palms of your hands

A sensitive child who doesn't like the feel of the floor


These are all characteristics and are also signs of high intelligence .

Most children are able to walk without having to crawl.


A solution to ease your mind when you can't do housework because you're behind



"Just going to the toilet makes me cry... I can't get any housework done..."


Following is a sign of deep love and trust for mom .

However, it's really hard not being able to do housework.


Practical solutions to ease your mind


Have the courage to let go of perfection

・Laundry is left in the basket without being folded

・Use frozen foods and prepared meals for dinner

Cleaning is minimal after the baby goes to sleep.


Housework involving babies

・Cooking while carrying a baby on your back

・Fold laundry in front of the baby

・Clean the bathroom together (within safe limits)


The magic words "Just now"

The follow-up will last for a few months at most.

Someday I'll say, "I was so cute back then"

There will surely come a day when you will look back on it fondly.


Being a smiling mom is better than being a perfect mom

It's so much more important for the baby.


Worrying about a 10-month-old who can't speak

The truth about individual differences when starting to walk




"He's already 10 months old, but he still doesn't call me 'Mommy'... Doesn't he know how much I love him?"



Even though I say "It's Mommy" every day,

It can be worrying when you can't find the words to say.


But don't worry. Not being able to speak doesn't mean you don't love them enough.


[The reality of individual differences in language development]


・First word (first meaningful word): 8 months to 1 year and 6 months

・Children who can't speak at 10 months: Approximately 60%

・Children who cannot speak at 1 year old: Approximately 30%


In fact, research has shown that children who are slow to speak tend to observe more carefully .


Signs of affection that come before words:

✓ Turns around when he hears mom's voice

✓ Smiles when you call his name

✓ Reaching out for a hug

✓ Behaving as if searching for mommy when she is not around


With these, even if you can't speak,

Your love is reaching out.


The emotion I felt when she said the word "Mama"

The longer you wait, the larger it will become.


Individual differences in when children start walking and why there's no need to rush



"Will he be able to walk by his first birthday? Is he okay like this?"


[Surprising facts about when babies start walking]


・Baby walking at 10 months: about 5%

・Children who walk at 1 year old: Approximately 50%

・Children who walk at 1 year and 3 months: Approximately 80%

・Children who walk at 1 year and 6 months: Approximately 95%


This means that half of children cannot walk by the age of one .


Additionally, children who walk slowly are characterized by:

✓ Careful and safety conscious

✓ Walking after balance is developed

✓ Fewer falls and less injury


A slow walker can also be seen as a cautious and intelligent child .


It's not the time of day that matters,

Seeing myself growing little by little every day

To watch over them warmly.


Your baby learns at his own pace

It is growing steadily.

Isn't that the most adorable thing about it?


Relieving anxiety about children not walking at 1 year old

The Complete Guide to Toddler Food Transition




"It's his first birthday and he's still not walking... is there something wrong with his development?"



If your child doesn't walk by his first birthday,

You may be worried, wondering, "Is this child's future okay?"


However, the reality is that about 50% of children cannot walk by the age of one.


[The future of children who don't walk at age 1]


・Poor athletic ability → ❌Actually , good balance

・Low intelligence → ❌Tends to be cautious and have high thinking ability

・Future poor athlete → ❌Less injuries and high safety awareness


Celebrities who actually started walking late:

・Einstein (1 year and 6 months old)

Many professional athletes


Characteristics of slow walkers:

✓ Excellent reflexes to put hands down before falling

✓ High ability to sense danger

✓ Prudent and don't try until it's perfect


That means your baby

"Walk only when it's safe to do so"

He is a smart kid who thinks like this.


That caution will be a great asset in the future.


Timing of transition to infant food and determining appropriate food amounts for 1-year-olds



"When my child turns one, will they be able to eat baby food? But it seems like he can only eat baby food..."


The transition to infant food is determined based on developmental status, not age.


[Criteria for transitioning to infant food]


✓ Can be chewed with back teeth (crushed with gums)

✓ Can eat with hands

✓ Drink water from a cup

✓ Enjoy mealtimes just like adults


Appropriate amount of food for a 1-year-old:

・Rice: 1 light child's bowl (80g)

・Side dish: 2 to 3 tablespoons

・Vegetables: 1 to 2 tablespoons


But the most important thing is not the quantity.


"Are you enjoying your meal?"

"Are you able to share mealtimes with your family?"


These people are likely to develop lifelong eating habits.

It's far more important.


Children who grow up around a table full of love,

I'm sure your child will love to eat.
