Why does the baby “lost” the memory before 3 years old? Psychologist: or related to 4 reasons

Why does the baby “lost” the memory before 3 years old? Psychologist: It may be related to 4 reasons.

They all say that children’s memories are short-lived. I thought about my childhood life carefully, and found that it seemed that I could only recall the kindergarten period at the earliest, and they were also some particularly vague memories, or some fragmentary impressions. 

However, when I asked my little nephew about the things he remembered deeply when he was a child (before 3 years old), such as where he went to play and what things he particularly liked, I unexpectedly found out that he was here. I told me many times when I was young, but when I was six or seven years old, I had no impression at all, and even the reminder to me seemed strange. 

Then the question is, where do all these memories of the child go? Did it clear it by itself? 

The key word for children at the age of 3 is “forget” < p>Before writing this article, I also asked many colleagues around me. They also said that even if they tried hard to remember, it seemed that they could only be traced back to the kindergarten class or elementary school, and the impression before the age of three was almost zero. 

Some people even said that they heard their parents say that when he was a child, his grandma led him to grow up, but he didn’t have any impression of him. It really deserves to be the “white-eyed wolf” in the legend. 

Some people only hear their parents say about themselves The scars on my body were caused by accidents when I was very young, but I also lost the impression at all. The scars have forgotten the pain. 

Why does the baby “lost” the memory before the age of 3? Psychologists give the answer

The reason why people generally “lost” their memories before the age of 3 is not because we have forgotten them over time, but because of human “infancy forgetting”. 

The concept of “infancy forgetting” comes from psychology. It means that when people are still in their infancy, their behavior or language is not fully conscious, so they will not form memories. Only when the brain matures and the mind is stable, children can Ability to associate foreign objects to form memory. 

Usually this period lasts until the child is 3 years old, which is the main reason why babies before 3 years old don’t remember things. 

Children’s memories before the age of 3 are “swept”, or are related to these 4 reasons

It seems that people’s “sweeping amnesia” is not simply individual memory loss. This phenomenon boils down to the following reasons Parents come to find out about the following four points. 

1) The brain “storage card” is too small to hold memory

Although the brain is not the memory of a computer or mobile phone, it is still in a mature stage before the age of 3, although “Received” or “processed” the information, but there is nowhere to “store” it, so it can’t be remembered. 

2) Difficulty in extracting explicit memory


Human memory is divided into explicit memory and explicit memory, such as learning to use tableware to eat, playing with toys, etc., belong to explicit memory, which forms a skill without externalization, but most of us use this kind of memory The narrative can’t come out. 

Extrinsic memory generally refers to the people and events we remember. Since it is difficult to “store” as mentioned above, then “extraction” is more laborious, which is why we only remember Can remember growing segments. 

3) The baby is in the unconscious period itself No memory

In addition, when babies are young, they are in an unconscious period, so they will be more obedient, but forgetful. After all, children’s day’s life revolves around eating, drinking and sleeping. These are basic life needs, so they are not worthy of special memory. 

4) Many useless memories have been “cleaned up”

There are data showing that people’s unimportant memories will be “cleaned up” , Replaced by new memories. 

For babies, some memories that are not used every day will naturally be “swept clean” by the brain over time. 

There is really nothing in the child’s “memory chest” Left? It’s not

this, many mothers are not calm, since sooner or later they will forget, then I usually take my children to play in vain? The situation is not so absolute. 

Things that touch their strong interest

People are more likely to remember strong emotions, and these strong emotions will be transformed into a physical instinct over time. 

Therefore, children who are more happy or particularly angry after encountering things will more or less plant seeds in their hearts. 

Learned life skills

Some life skills Skills do not require special memory for children, as long as they practice repeatedly, they can become a child’s ability to survive. 

Summary: For children, before the age of 3, it is not for them to remember what, but what to feel, and then to transform into something, and eventually become a habit or mood that affects the child’s life. No matter how skinned the child is, these 4 parts cannot be hit. The third one is often ignored by parents.

Naughty is a child’s nature, but it is really annoying to get into trouble! You will never know how annoying a child can be without raising a baby. But childish and angry, we can’t do it if we can use our mouth to educate, and we can’t do it even if we are angry. 

After all, it is his own birth, and there is too much power disparity between the adult and the child. You don’t even know if the child is broken. Especially the 4 parts below are very fragile and can’t stand up to an adult! 

Behind the head

Some parents have bad habits If the child makes a mistake, he will give the child a quick look at the back of his head, depending on the mood. But children cannot hit the back of the head, because the nervous system that affects our physical and intellectual abilities is distributed in the back of the head and the spine. 

If you miss a heavy hit, it will affect your child’s intellectual development and coordination ability, and it will really hit your child “stupid”. It may also cause concussions and cause other problems. 


Slap can easily lead to tympanic membrane Destroy, affect hearing, and even cause deafness in children. After the tympanic membrane is damaged, the middle ear will lose its protection. Bacteria, sewage, and foreign bodies from the outside can easily enter the middle ear and cause infection and inflammation. If it is not treated in time, it may also cause meningitis. 

We all say that slaps are not slapped in the face. In fact, the same is true for children. The psychological harm to children caused by slaps is much higher than the physical harm. We must pay attention to protecting children’s self-esteem. 


Spanking children should be the most common I have spanked, and many parents think that it’s okay to have more meat on the butt of the child. 

But this is not the case. The buttocks seem to have a lot of flesh, but in fact there are many nerves and tissues. Our spanking may cause local soft tissue contusion, redness and infection, and severely cause the whole body symptom. It seems that spanking has little effect, but adults who have a lot of strength can easily have problems with spanking. 

Twisting ears

Some parents feel that slapping is right If the child is not well, just twist the ears instead. But twisting a child’s ears will not only cause ear damage, cause tears in the outer ear, it can also cause hearing loss, tinnitus, and even damage to the tympanic membrane. 

We can’t think that twisting a child’s ear is just twisting the outside of the ear, and it has no effect on the child’s hearing and the inside of the ear. These are all interlinked, and the muscles on the outside of the ear are related to the inside of the ear. 

When children are mischievous, the solution to violence is To make the next move, communication should be the first priority. Because violence brings not only physical harm to children, but also psychological harm. This will also make children use violence to solve problems, which is very bad for children’s growth. 

So no matter how angry we are, the child can’t hit these 4 parts. Once we miss a hit, regret is useless.
