A child who was so lovely, pretty, and kind that you wouldn't mind putting her in your eye starts to change one day.
The child who used to blindly follow his mother's words starts shouting out emotional words like "No!", "I don't want to!", "I want to do it!", and "It's mine!"
What's inside our three-year-old's heart? If only we could understand his inner thoughts, if only we could understand his enigmatic behavior, if only we could love him for who he is, even from now on, could we return to our happy relationship?

All children are unique, each with their own temperament and overflowing personality.
Among them, especially two- and three-year-olds who act out unexpectedly several times a day cannot be at ease even for a moment.
I try to stop him out of concern that something might go wrong with him, but the answer I always get is, “No!”
Many mothers become hysterical and yell at their children when they hear them say “No!”
But as parents, you absolutely must know this.
The word 'I don't like it' is the earliest form of a child's self-assertion.
As children begin to communicate with the world through words and develop their own tastes, they begin to develop their inner selves and try to become independent. It is at this point that the word "I don't like it" appears.
At this age, you should avoid causing conflict with your child by responding too emotionally when they say no.
Rather, we should naturally accept the child's attitude of saying "no!" because at this age, "no!" is a part of the developmental process.


Also, three-year-olds are in the process of developing an inner sense of self.
You have just entered the world of verbal communication, and it is a time of explosive activity that makes it difficult to stay still for even a moment.
Besides, he is still just a little child who wants to monopolize his mother's arms.
Understanding the developmental process and psychology of a three-year-old will help you understand their behavior, which can be confusing and frustrating, and will significantly reduce parenting stress.


This book approaches what it means to be three years old from a child's perspective, starting around the time they turn two.
Two- and three-year-old children are telling us why they act the way they do, how they feel and think, and what they want and need from their parents.
It is written in a way that makes it seem as if a three-year-old is talking directly to his mother. It carefully considers the child's level of development and expresses thoughts that children of the same age cannot express in words, allowing us to read the thoughts of three-year-olds in detail.
The author's extensive research and experience have allowed him to accurately identify and pinpoint the universal developmental characteristics of three-year-old children.
For example, asking a child to teach them how they are feeling, asking them to satisfy their possessions, or asking them to be patient until they can express their needs more sophisticatedly because their whining is an expression of their needs are important guidelines that parents can apply to their child-rearing practices and bring about surprising changes.

The more you understand about children, the more strategies you can use to address the challenges you encounter while living with them.
This book emphasizes the importance of parents first understanding the developmental level of their three-year-old child rather than blindly trying to correct their child's behavior.
Rather than looking at right and wrong behavior from an adult's perspective, we need to look at it from a perspective that is appropriate for the child's developmental level.
By understanding a child's developmental level through these efforts, parents can more easily predict their child's behavior, which can help prevent or minimize many conflicts.


This book will help you understand the developmental level and behavior of two- to three-year-olds, and you will learn how to deal with the various problems we face as parents every day.
It will also serve as a guide for happier parenting, along with a message of hope for parents who are constantly struggling with the frustration, anger, and discipline issues that come with parenting.
