First, the child has a delicate mind. This is actually not a question of educational methods, but the child's mind is very delicate. Because some children are very good at observing others, he knows when adults are unhappy and when to do something. He knows it very well in his heart. In fact, it is because he is very delicate and good at observing other people's eyes. Just like there was a child in a Korean drama before, she was also very stable. In the face of his parents' divorce, he didn't make much noise, but just accepted it silently. But he is actually a child. Even if he is mature and steady, all thoughts are still a child.
Second, the impact of the family environment This is not just because of the child, his mind is very delicate. In fact, it is also possible that the whole family environment is very stable. If the parents are also a stable person, then the child will naturally be a stable person. This is why some people say that the environment will affect a person, and some even say what kind of person a child may be. So in these stable children's families, parents may be very stable.
Third, the education methods are different. The child has a steady personality, and it is not a problem to raise the child, but because his personality is like this. In this case, no matter what kind of upbringing is adopted, his personality may be like this. If you want your child to be full of energy, or stop hiding so many worries in your heart, you may need parents to actively guide your child. Every family, parents' education methods are different, so this may also affect the child's personality, but this is not because the education methods are wrong.
