A hot steady seller that has sold 4 million copies worldwide
Revised edition of "Mom, I'm Growing Up" published!

A book that covers the major growth and changes that occur in a child from birth to 20 months.
This is the time when parents have the most difficulty taking care of their children, and it is also the time when children absolutely need a helping hand.
If parents can understand what's going on in their child's head during this time and understand that their child isn't trying to make things difficult just to upset their parents, they'll be able to endure this difficult time more easily.

In particular, in this revised edition, the existing content has been updated and supplemented with the latest information, and the content on 'sleep' has been supplemented for parents who are concerned about their babies who have trouble sleeping.
Additionally, some important precautions to keep in mind regarding baby jumping have been added.
In particular, an album book and a ‘Our Child’s Leap Checklist’ bromide are provided as appendices.

Babies don't cry for no reason.
The reason babies cry so much is because they feel anxious during a period of rapid growth and development.
Of course, growth and development are very positive changes for babies.
Because you can grow and learn new things that much.
So, this is something to celebrate!

Babies are interested in the world around them from the moment they are born.
You can be more interested in that than this.
The baby listens and looks at you.
Babies allow their surroundings to influence them.
Babies try their best to figure out everything as best as possible.
After going through so much trouble trying to figure out the world, I became cross-eyed, got tired and had cramps, and started hiccuping.

At 10 weeks, your baby no longer demands your attention day and night.
The baby became more independent.
The baby's attention is focused on the surrounding environment.
To people, animals and things.
The baby suddenly knows and realizes so much more.
Also, now he doesn't want to just lie on his mother's lap all the time.
The baby is lively and active, and keeps asking to be raised.
He will only want to be around his mother when something interests him.

All babies leap at the same time.
This is something that cannot be deliberately brought forward or delayed.
It's similar to puberty.
There is a set time when we will experience puberty.
No matter how fast one's mental development is, puberty does not come at the age of eight.
Puberty comes to everyone at roughly the same age.
However, the specific impact of puberty varies from child to child.
Some children stubbornly rebel against everything, while others remain silent.
Although the leap in mental development is different from puberty, there are many similarities.
Babies also experience a leap at about the same time.
However, the behavioral patterns observed during jumping vary from child to child.
Even for the same baby, there may be times when it is particularly difficult.
This is normal.

A period of calm returns between 40 and 45 weeks.
For 1 to 3 weeks, babies are praised for being independent and cheerful.
Now the baby is interested in everything from people to animals, flowers and mosquitoes.
Most babies now prefer to play outside rather than stay inside.
Suddenly, the importance of other people increases.
The baby is ready to relate to others and play with them.
The world that a baby can see has become much wider than before.

Around 15 months of age, mothers notice that their babies are becoming more comfortable.
The baby once again shows a strong desire to explore.
The baby gradually becomes more determined, thinks differently, handles toys and objects differently, and smiles at different things.
This is because the ability to perceive and apply 'principles' is awakened in babies during this period.
A whole new world opens up with so much to discover under the theme of 'principles'.

In adults, the day-night rhythm influences the secretion of melatonin, also known as the "sleep hormone."
So, as soon as it gets dark, the pineal gland in the brain produces melatonin (but a newborn's brain cannot yet produce melatonin).
Other hormones, such as cortisol (a stress hormone that increases alertness), are secreted less when it gets dark.
So, you can relax and fall asleep easily.
Therefore, in order to sleep well all night, there must be a sleep-wake rhythm and certain substances must be secreted in the brain.
