There is no right answer to parenting, but to protect your child,
There is essential knowledge you need to know!
A parenting textbook for the first year of life, all in one volume.

“How do I make a round head?”
“I keep vomiting. Is that okay?”
“The area around my mouth is red. Could it be an allergy?”

Even after going through the difficult pregnancy and childbirth, new parents face another challenge: childcare.
From colic to sleep habits, nutritional supplements, and even baby care, there are so many things you want to know, but taking your child to the hospital can be overwhelming, and with so much information online, it can be confusing to know what to do.
In these situations, if you listen to the advice of those around you, you may end up doing something that is harmful to your child.


Parenting is not difficult or overwhelming.
The author, a professor who treats critically ill newborns in a neonatal intensive care unit and a father of a three-year-old, says that new parents can reduce their fears by knowing and understanding the changes that occur in their child during the first year of life.
If you know when to go to the emergency room and what developmental milestones your child should show at each stage, you can raise your child safely without panicking or feeling overwhelmed.


The most important thing in raising a child between 0 and 1 year old is the desire for the child to grow up ‘healthily.’
Many things we do in hopes of making our children smarter, taller, or faster walkers actually do more harm than good.
For example, there are still widespread misconceptions about parenting, such as that using a walker helps children grow taller or that a walker helps children learn to walk.
Based on the latest medical knowledge and experience, the author distinguishes between conditions that new parents should be concerned about and those that they should not, and selects and provides parenting tips that are beneficial to children.


The author has included in this book only the essential knowledge needed to know for the first year of life, from making a round head to allergies, seizures, and sudden infant death syndrome.
Additionally, the author increased reliability by organizing the content based on frequently asked questions in pediatrics.
The author's experience as a father of a 3-year-old child also resonates with many new parents.
I hope this book will inspire courage and confidence in countless parents who are worried about raising their children.

However, the parenting information that is popular these days seems to be focused on raising children to be ‘smart’ rather than on their health.
And as uncertain claims become popular and consumed, we often see parents without access to essential information.
In the midst of all this chaos that parents face, I found my role as a father raising a child and as a pediatrician working for children's health.
“We must spread accurate information widely so that children can grow up healthy and safe!”

However, breastfeeding, especially breastfeeding, requires caution when using pacifiers.
The shape of a baby's mouth when sucking on the mother's breast and the shape of its mouth when sucking on a nipple are different, so if a baby is not careful, they may get confused about how to suck on the mother's breast while sucking on a nipple, which can lead to 'nipple confusion', which means they cannot breastfeed properly.
In such cases, breastfeeding may not proceed smoothly, and the baby may experience symptoms such as dehydration, hypoglycemia, and jaundice, while the mother may experience pain such as breast engorgement and sore nipples.
So, if you are breastfeeding a baby, it is recommended that you do not use a pacifier during the newborn period, and that you use it after the baby is over 1 month old.

It is very important to stop feeding when your baby wants to stop feeding.
When I explain how much to feed a baby, I always say, feed as much as the baby wants.
If the mother or father decides how much the child eats and force-feeds the child when he or she is full, or if the mother or father abnormally increases the amount of feeding by comforting the child with food even when the child is crying for other reasons, this is also a bad habit that can cause colic.
Feeding your baby as much as he or she wants is the beginning of respecting your baby.

However, recently, cushions that help children sleep in a slightly upright position have become popular, claiming to prevent reflux.
As a pediatrician, I do not recommend using this cushion as it not only does little to prevent reflux, but it also compromises your baby's sleep safety.

It is important to make your baby turn his head from side to side while he is sleeping.
The way to do this is to lay the baby on his back.
Imagine putting a baby to sleep with the wall on the right and the mother on the left, with the head and feet turned in the opposite direction.
So this time, the mother will be on the baby's right and the wall will be on the baby's left.
The baby wants to fall asleep looking at his mother, so this time he falls asleep looking to the right instead of the left.
It would be nice to do this every day, but for those who find it difficult to do so, it would be fine to do it once a week.

One thing I think is particularly important is being able to sit still.
Baby food is more viscous and contains lumps than formula or breast milk, so if it accidentally goes into the airway, it can cause choking.
So, you should eat in a sitting position, not lying down.
Because the age at which a child begins to sit up varies slightly from child to child, the timing of starting solid food cannot be determined simply by age.

Not having too many toys around your child is good for both safety and development.
When trying to attract a child's interest, stimulate development, or communicate with a child, concentration is important.
When there are a lot of interesting toys around, children's attention wanders everywhere and it becomes difficult to concentrate.
That's a drawback in terms of inducing various developments.

In our country, the most popular baby product purchased as a gift is a baby walker.
However, walkers are banned from sale in Canada, and the American Academy of Pediatrics is petitioning to ban their sale and production.
Pediatricians in our country also recommend against using walkers.
