There is a saying in our hometown: The old man is a, the old man is a traitor, and the three are cunning.
Presumably, if there are a bunch of kids in the house, their personality traits are distributed as follows:
Home
Big kids, generally generous,
The second child is "treacherous",
The three children are "cunning" and also make trouble.
This folk proverb is often a law that has been observed and summarized through many practical experiences.
Many times, it is also very accurate to apply it to some families.
In fact, this saying can probably be summarized as:
the child's IQ and character,
From big to small
Become smarter and better in turn.
In short, the further back the better.

I know you'll immediately have a question:
Mr. Four Tigers, how old are you in the family?
Hey hey hey!
I am——........
Do you want to use this law, guess what kind of character I have?
——Tell you, it's not easy!
I am the fourth oldest, so I am called "Four Tigers"!

Now there are too few families with many children, and people can no longer observe this phenomenon.
However, with the liberalization of the three-child policy, there will be more and more multi-child families in the future.
Will this rule still apply?
I have a guess.
In fact, there are deeper reasons behind the law of this folk summary.
(The following paid to watch.... ）
Hahaha, just kidding, scare, refresh you.
My guess, free and public, is for reference only.

The law behind this saying is:
Parents' emotions directly affect a child's personality and IQ.
Why "Boss"?
In general, when most parents have their first child,
It's the first time to start a family, to raise children,
The arrival of the first child has added a lot of pressure and difficulties to the family.
The run-in between the husband and wife at this time has not yet been fully completed,
The pressure on family harmony is further increased,
This is also the time when young people are beaten by society.
The couple spent their honeymoon in the world,
Begin to face the beatings and tests of real society.
Life is not always a honeymoon.
The real life is cruel and even more cruel.
When the first child is born,
It is often also the most intense period of quarrel between husband and wife.
Children who grow up in the heated quarrels of their parents,
The young mind is strongly hit by the emotions of the parents,
Unconsciously, I was negatively affected by my parents.
The development of the mind and intellect is severely suppressed and bound.
So, the boss is thick,
Another meaning is that the mind is bound and suppressed.
Why "old two adulterers"?
When the second child is born,
At this time, the run-in between the husband and wife went on for a period of time
I also have experience with parenting,
Husbands and wives have also matured a lot, and there will be fewer quarrels.
The growth environment of the second eldest is relatively old,
It's going to be better, it's going to be a little bit calmer,
So the second will appear bolder and more flexible than the boss.
Why "three cunnings"?
Wait until the third is born.
The couple is a bit older
The economic conditions are also relatively good
The experience of parenting is also enriched,
Most importantly,
Both husband and wife are also old,
Finally began to experience:
The joy of parenting, the harmony of the family is important.
That is to say: quarrels are getting less and less, and it is getting better and better for children.
Therefore, the growth environment of the third elder is relatively the most peaceful.
The environment in which the third elder grew up was relatively the most free.
At the same time, the third elder has many lessons that the eldest and second elders have learned from their failures.
Therefore, the third is often blessed!
Therefore, the third elder generally seems more cunning and selfish.

In fact, they were born to the same parents,
The congenital conditions inherited by the three children are the same.
Because the acquired environment is different
Three children will show different personalities and developments.
Of course, this is just a guess
Folk sayings are also just a high probability of accuracy
There are also many exceptions in reality.
Ultimately
It's not actually the sorting of siblings that works
Rather, its associated acquired environmental effects are at play.
One of the most important factors
It's the emotions of the parents.
Parents are emotionally stable,
Family atmosphere peaceful,
No matter how old you are, you will develop in an all-round and balanced manner.

So, I finally came to the conclusion:
Parents
If you want to make your child healthy, happy and smart
Start by controlling your emotions and never arguing.
The home must be quiet and peaceful.
Children it will naturally blossom into beautiful exuberant flowers.
