2-month and 3-month old childcare
Vaccinations, neck support, night crying
Understand all the "whys"
"Four injections for my little child... is that really okay?"
"He's only three months old and his neck is still wobbly... is he growing normally?"
"I wake up every two hours in the middle of the night and my physical strength is at its limit..."
In front of the adorable newborn baby,
Every day is a series of love and anxiety.
We want to wrap this little life in our love and protect it.
But I can't help but worry, "Is this really okay?"
Supervised by a midwife who has cared for 15,000 babies over the past 30 years,
To answer moms' questions like "Why?", "How come?", and "Is this right?"
I will answer your questions wholeheartedly.
By the time you finish reading this guide,
"Oh, so that's the reason!"
"I see, so it's okay."
With these new discoveries and relief, your heart will surely feel lighter.
For my beloved child,
Let's turn anxiety into peace of mind with the right knowledge.
Is it really safe to give four vaccinations at the same time at 2 months of age?
The scientific basis for the 98.7% safety rate
Why a fever of 37.5 degrees is normal
The moment I was told at the pediatrician's office that "your child will be vaccinated when he turns two months old,"
Didn't your heart feel like it was being squeezed?
"Is it really okay to give my child four injections at once?"
This anxiety is a common feeling felt by mothers all over the world.
But actually, there is a deep reason to love vaccinations.
According to the latest data from the Ministry of Health, Labor and Welfare,
The safety rate for simultaneous administration of four vaccines is 98.7% .
This means that 987 babies out of 1,000 will acquire immunity without any problems.
Why give four shots at once?
It's to protect the life of our beloved child from illness.
At around six months of age, the immunity given to babies by their mothers disappears.
Before that, it is important to ensure that your pet is immunized.
It's the best gift of love for your baby .
A fever of 37.5 degrees after vaccination is actually "proof that your immunity has been firmly established."
This is a sign that your baby's body is trying hard to protect him.
This discovery will surely change the way we look at vaccinations.
Is it too late if my baby can't hold his head up after 3 months?
The fact that 50% of babies cannot conceive
The correct way to judge
Seeing other babies at the support center
"My child's neck is still wobbly... is it too late?"
Have you ever felt such anxiety?
In fact, here's a surprising fact that many moms don't know.
Looking at actual survey data from the Ministry of Health, Labor and Welfare,
Only 50% of babies can hold their heads up at 3 months of age .
This means that half of the babies are not yet able to hold their heads up.
It's never too late for your baby.
"Oh, is that so?"
Many mothers will breathe a sigh of relief when they learn this fact.
Furthermore, the real sign that 90% of mothers miss is that their baby is able to hold up its head.
Being able to "lie face down and lift your head 45 degrees and hold that position for 5 seconds."
This is a much more accurate criterion than stability when held upright.
If your baby doesn't like lying on their stomach, we recommend the "three-minute stomach rule."
Just 3 minutes on a soft mat when you're in a good mood.
Rather than forcing them to do something,
"Encourage growth in a fun and natural way."
This is the best thing for your baby.
Please trust your beloved child's pace and watch over them warmly.
How long will breastfeeding every two hours through the night continue?
The scientific reason for day and night reversal
The difference between a child who sleeps 5 hours
"My baby is already three months old and still wakes up every two hours at night..."
"I heard that my friend's baby sleeps for five hours straight, but my baby..."
Moms who are exhausted both physically and mentally from breastfeeding in the middle of the night,
Thank you very much for your hard work .
Here are some eye-opening scientific facts you should know.
There is a lot of individual variation in the sleep patterns of babies between the ages of 2 and 3 months.
Why is there such a difference?
This is because the rate at which each baby's "biorhythm" develops varies .
To adapt to the 24-hour rhythm of adults,
For some babies, it can take as little as two months, but for others, it can take as long as six months.
In other words, whether your child sleeps for five hours or wakes up every two hours,
Both are normal and healthy signs .
There are ways to quickly resolve the day-night reversal.
At 7am, I always open the curtains and let in the sunlight.
Keep the room dark after 8pm.
It may take 2-3 weeks for the effects to be seen,
There will definitely be an easier day .
It may be difficult now, but frequent breastfeeding at this time is
It's also a precious time for mother and baby to bond.
"Let's work hard together just a little longer."
That gentle feeling is sure to be conveyed to the baby.
Is a 25g weight gain per day too little?
Signs of insufficient breast milk
The true meaning of growth curves
"My baby's weight is at the bottom of the growth chart...maybe I'm not getting enough breast milk?"
"I'm only gaining 25g a day... is that too little?"
Mom stares at the scale every day and experiences ups and downs.
I can understand how you feel .
But here's a comforting truth I want you to know.
Growth curves are "averages," not "normal."
Even if a child is at the bottom of the curve, as long as they are growing steadily at their own pace,
There's no problem at all .
There is an even more surprising fact.
The recommended daily weight gain is 25-30g.
In fact, an increase of 15g or more is within the normal range .
Whether the baby is satisfied
You can judge by their mood rather than their weight.
✅ Baby is in a good mood for more than 30 minutes after feeding
✅ Urinating more than 6 times a day
✅ Move your arms and legs a lot when awake
✅ I started to smile
If you have these signs, there's no need to get too excited or upset about your weight number.
When it comes to breast milk, babies have an instinctive ability to drink as much as they need.
The mother's body also produces only the amount needed to meet the baby's needs.
It's a perfect partnership .
Don't be fooled by the numbers, but take a good look at how your beloved child is doing.
Why does the crying occur during the devilish three months?
I cried for two hours straight until 5pm
biological reason
"Every evening at 5pm, he suddenly starts crying..."
"No matter what I do, he won't stop crying, and I want to cry with him."
Moms who are troubled by the so-called "terrible three months" and "twilight crying"
You are never alone .
In fact, there is a deep biological reason for this phenomenon.
At around three months of age, your baby's brain is undergoing rapid development.
In particular, the part of the body that controls the "internal clock" begins to develop.
The brain becomes confused.
Around 5pm in the evening is the time when the human body clock is at its lowest level of alertness.
At the same time that adults get sleepy, babies
"I feel a bit uneasy, but I don't know what to do."
This is the situation we end up in.
"I see, that's the reason!"
Knowing this scientific background will change the way you look at babies.
The crying usually subsides naturally by around 4-5 months of age.
It may be difficult now, but this is also proof that your baby is growing.
When your baby won't stop crying even when you hold him/her,
I thought, "This child is also working hard and growing up."
Just spending that time together is enough.
There's no perfect solution, but your baby is just confused.
I'm sure your mother's warm feelings are conveyed to you.
Is it okay if my baby doesn't laugh or follow my eyes?
Individual differences in development and
The boundaries you should really worry about
"Compared to other children of the same age, my child seems less responsive..."
"He's three months old and still not smiling... is he developmentally delayed?"
"It seems like I can't track it... is this okay?"
Seeing other babies at the support center
I completely understand the feeling of comparing your child to yours.
But here's a comforting fact I want you to know.
The range of what is considered "normal" development is much wider than you might imagine.
Social smiling appears between 2 and 4 months of age .
It is not uncommon for babies to start laughing after four months of age.
The same goes for tracking.
Even if you can't follow it perfectly, if you can just follow it with your eyes,
It's a great sign of development .
There are actually very few signs that you should be really worried about:
❌ Does not respond to sound at all
❌ 4 months and still can't make eye contact
❌ Significantly reduced limb movement
Other than these, most of it is within the realm of personality .
Even if the child's reaction is weak, that is also an important part of their personality.
Some children are reserved, while others laugh a lot.
Both have great personalities .
"Recognizing my child's individuality"
That may be the most important role of a parent.
Don't rush, trust your child's pace, and watch over them warmly.

💡Environmental improvements also affect development
Is it abnormal if my poop is green and I've been constipated for 4 days?
30 common worries
Criteria for determining normality and abnormality
"My poop has turned green, is this a sign of illness?"
"I haven't had a bowel movement for four days... should I go to the hospital?"
"I have red bumps on my face... could it be allergies?"
With the daily changes in your baby,
"Is this okay? Or is it abnormal?"
I understand very well how you feel anxious about each and every thing .
In fact, 99% of what moms worry about is normal .
[About the color of poop]
Green poop is just the color changed by the components in breast milk or formula.
Yellow, green and brown are all within the normal range.
You should only see a doctor if the discharge is white or bloody .
[About constipation]
Babies aged 2-3 months have immature digestive tracts,
It's not uncommon for it to go 3-5 days without coming.
As long as your baby is in a good mood and not bloated, it's fine to just wait and see.
[About facial eczema]
99% of eczema cases in babies 2-3 months old are "infant eczema."
This is a natural phenomenon caused by active sebum secretion.
Keeping it clean and moisturized will improve it naturally .
"Oh, this is normal too."
Just knowing this will make your daily worries much less.
What you should really be worried about are fever, vomiting, difficulty breathing, etc.
Only if the baby is clearly in distress.
This is proof that you are closely observing your beloved child.
Cherishing those loving feelings,
Please relax a little and watch over them.

💡Communicating with your baby is also helpful.
Which is correct: room temperature 22 degrees or 26 degrees?
Baby's thermoregulation mechanism
Seasonal Settings
What is the ideal temperature for a baby's room?
"My hands and feet are cold. Are you okay? Or are you cold?"
"I heard it's 26 degrees in the summer and 22 degrees in the winter. Is that true?"
I stare at the thermometer every day,
If it changes even once, I get worried.
I understand very well how mom feels .
In fact, there is a surprising secret to how babies regulate their body temperature.
Babies have a higher body temperature and a more active metabolism than adults.
Therefore, the temperature that adults feel is "a little cool" is
It's just good for babies .
[Optimal temperature by season]
Spring and Autumn: 22-24°C
Summer: 26-28°C (within 5°C of outside temperature)
Winter: 20-22°C
But what's more important than the numbers is
"Keep an eye on the baby."
How to tell if it's comfortable
✅ If you touch the back of your neck and it's sweaty, it's too hot
✅ Even if your hands and feet are cold, your chest and stomach are warm → OK
✅ Sleeping well → Optimal temperature
✅ Your face is not red → You are not too hot
"I see, so I don't have to worry about my hands and feet getting cold!"
This discovery will surely make daily temperature control easier.
Babies cannot say "hot" or "cold" on their own.
That's why a mother's loving observation is so important.
It is the best thermometer .
Don't get carried away by numbers, but take a good look at your child's condition.
Trust your own judgment and value it.

Encouragement to nurture the budding language
communication
"Recently, he's started making sounds like 'ahhh'. What does that mean?"
"How do I respond?"

A cute "ah-uh" sound.
This is a special message from baby to mom .
This phenomenon is called "cooing"
The first step in verbal communication .
The baby hears his own voice
They enjoy discovering, "So this is the kind of sound it makes!"

Respond gently with something like, "I see," or "That's fun."
Look them in the eye, smile, and respond in the same tone.
The baby will be delighted, saying, "We've had a conversation!"
The accumulation of these small "conversations"
It lays the foundation for future language development.
Even when you're busy, you can listen to your baby's moans
Time to listen and respond
A precious moment to deepen the bond between parent and child .
You don't have to give a perfect response.
Just respond with a loving voice from your mother,
The baby will be very satisfied.
How can I get dads to participate in childcare?
Nighttime breastfeeding sharing technique and

[Childcare tasks that dads are good at]
・Bath (heavy work, fresh for the baby)
・Changing diapers in the middle of the night (quickly changing them while breastfeeding)
- Putting babies to sleep (low voices are soothing to babies)
