A special ability that all mothers in the world have
The Secret of 3 Hours of Magic Time That Induces Happiness Hormones

If you put a gauze soaked in the mother's amniotic fluid on a newborn's nose, the baby will move its mouth and sleep peacefully. If you put gauze soaked in the mother's breast and another person's breast on each side of the baby's face, the baby will turn its head towards the gauze soaked in the mother's breast milk.
A baby that was protected by amniotic fluid at a constant temperature in the mother's womb must continue to feel protected by the mother's scent and constant temperature after birth in order to grow up healthy and happy.
“Mother’s scent is a symbol of parental love, but it is also the reality that must be given” (p. 12).

Dr. Lee Hyeon-su emphasizes the 333 rule of parenting, which states that since the brain develops over the next three years after birth, parents must spend at least three hours with their children until the critical period of three years of age, and that even if they must be separated for unavoidable reasons, they must not be separated for more than three nights.
The problems of the children I met in the counseling room were almost always caused by not fulfilling the 333 rule, and although the duration was different, they were resolved when the children returned to spending time with their parents.

In an environment overflowing with all kinds of educational programs, coaches, experts, and educators, the author emphasizes that the most important thing for a child under ten is the sense of security that comes from the scent of his mother, and that the happiest moment for a child is when he laughs excitedly with his mother and father.


No more half-assed parenting
Mr. Santa, I need some daddy smell too

Just because the title of the book is 'Mother's Smell for 3 Hours a Day', it doesn't mean that only mothers are important in child rearing and that fathers' roles are secondary.
In this completely revised edition, the author says that 'daddy's smell' is essential for growing up as a happy child.
“Adding dad’s scent to mom’s scent is not a simple addition like 1+1, where halves come together to make one.
“It triples and quadruples all the positive effects, creating a dazzling result where the child is happy beyond being safe and healthy.” (p. 185)
Children raised by fathers who actively participate in their children's growth and education are more likely to develop language skills, social skills, and intelligence, and are more likely to be physically and mentally healthy and socially successful.
It is enough to just play with your child and do physical activities outdoors, such as at a playground or in a valley, or to just watch your child with interest in the same space.
Additionally, they can actively share household chores with their partners in co-parenting, utilize the Internet to propose policies that support childcare, or take the lead in creating a social atmosphere that allows them to take parental leave or use flexible work hours while working.

Instead of the shy dad who only shows up to pat the shoulder on important days like birthdays, entrance ceremonies, or graduations, the smell of Mr. Santa, a dad that the child can run to and hug and rub at any time, is not an option.
A child who inherits the DNA of both his or her mother and father grows up in the direction of his or her parents.
Only the time filled with the love of the co-director can guarantee the child a happy ending.
This completely revised edition is a must-read not only for mothers but also for fathers who need to give their children a sense of fatherhood.


Raise a happy and healthy child rather than a child who is good at studying.
The Law of Love That Will Help You Live Your Whole Life as a Strong Adult

South Korea, a country where early education is essential, with children taught not only Korean but also English from kindergarten, has the highest level of unhappiness among children in the world.
There are many children who are good at studying but depressed, and many successful but lonely adults.
The gifted education and early childhood education currently prevalent in Korea ignore the stages of brain development.
Dr. Lee Hyeon-su emphasizes early education over early education, and says that, due to the stage of brain development, the time spent running around until the age of six should be at least five times longer than the time spent learning letters, and that even elementary school students should run around at least three times longer than the time spent going to cram schools until the third grade.
Until the age of ten, when the frontal lobe explodes, the emotional brain must develop stably, so it is necessary to actively provide 'motherly scent'.
Emotionally stable children take the initiative in building their own lives and become adults with strong inner strength even after leaving their parents.
Dr. Lee Hyun-soo's unique know-how for providing "mom scent" for at least 3 hours a day will shine in real-life parenting.


▶ Playing with my son for 3 hours
Most sons prefer dynamic activities over static ones.
Boys should not be confined to confined spaces, but should be allowed to run free.
If you have time, it is best to take them outside.
Until your child grows up to a certain extent, you should give up on keeping the house tidy and accept that it is normal for your child to make a mess.


▶ Read a book for 15 minutes a day
While it's not a good idea to teach your child Korean at such an early age, it's crucial to spend three hours with your child reading to them in your own voice.
15 minutes a day is enough.
Reading a lot of books to your child not only stimulates their curiosity and improves their comprehension, but also gives them a sense of security that they are with their parents.


▶ Nature is a comprehensive gift set
Nature is a fascinating subject that can captivate children.
Finding toys on your own by the water or in the forest can help develop your creativity and give mom and dad a break too.
If you run around freely in nature, you will naturally build up your physical strength, develop a spirit of challenge, and cultivate an optimistic attitude.


▶ 15-Minute Desire Delay Training
Research shows that children who can control their urges do better academically, are healthier, and happier than those who can't.
When your child is around four years old, try training them to hold back on something they want to do for about 15 minutes.
If they wait 15 minutes, they are given two snacks or read more books than usual.


▶ Creating a Gold Standard
From around the age of four, a gold standard, a set of principles to be followed throughout life, is established as a consistent standard for the family.
At this time, the gold standard is not to exceed five.
It is better not to set as a gold standard things that must be kept but are impossible to keep 100%, such as 'not lying'.
