Don’t remember anything before the baby is three years old? At this age, you may experience “memory cleaning”
What we generally say “notes” refers to the memory of childhood when we grow up.

Scientific research has shown that with age, human memory of before 3 years old will gradually disappear .
The disappearance here does not mean that this memory is completely erased, but that a lot of unimportant information is stored deep in the brain, leaving only some impressive information.

But most people have no impression of things before the age of 3, so they have There are even people who say that “3 years old don’t remember anything”, and some people even think that when babies reach a certain age, they will experience “memory cleaning.”
Case: The baby does not remember anything before the age of 3, which proves a happy life.
Before the age of 3, most children cannot use rich vocabulary to explain things, and as they age, new information is sent In the brain, old information will gradually be overwritten. Except for the more stimulating information, other memories are often buried in the bottom of my heart.
But under normal circumstances, memories with a strong stimulus are mostly similar to “where did you fall”, “being beaten and scolded by parents” and other information that carries painful feelings, causing certain physical and psychological shocks to children, so they will be impressed. profound.
Just like some time ago, the 5-year-old Junjun and his father watched photos of playing out when they were young, but their memory never remembered them.
The military father smiled and said to him: “These are all you went before 3 years old. It is normal for children to remember.”
But the military thought of the kindergarten friends, once said After I fell off the bed, I cried for two hours, and I still feel pain when I think about it. Junjun told his father this, but he didn’t expect his father to be stumped.
It can be seen that the children’s memories before the age of 3 have not been forgotten, but other factors have caused them to seal these memories deep in their hearts.
When babies reach the age of three, they will experience “memory cleaning”
For babies, 3 years old seems to be a watershed in memory. Things before 3 years old are naturally forgotten as they grow older.
Many parents in life have reported that babies have very vague memories of before the age of three.
Lele mother: My child is 4 years old. He obviously took him out for a trip last year. Ask him again today. The child has forgotten all about it. He just remembered that he had taken a plane.
Mom Qiqi: When my son was 2 years old, he took him to the playground, but he fell and took him to the playground when he was 3 years old. He still remembers this, but he can wait until he turns 4 this year. At that time, he completely forgot.
Jingjing’s mother: My child fell into the water when he was 2 years old, and since then he has not dared to touch the water until he is almost 4 years old this year. When I saw other children go swimming, I returned home. I told me that I was going to learn to swim, but I didn’t even remember that I had fallen into the water.
Similar cases like this one after another will naturally give parents a theory: After a baby turns 3 years old, he will experience “memory cleaning”, and everything in the past may be forgotten.
▲The reason for “memory cleaning”
Psychologically, the above-mentioned phenomena are called “childhood amnesia”.
The psychologist Freud attributed the phenomenon of “memory cleaning” in children to the characteristics of memory and the children’s own development.
Due to the limitation of physiological development, the memory in the infant’s brain is mainly composed of sensory memory and short-term memory. Most things that happen at age are difficult to preserve in the brain.
Since babies can “clear their memories”, is early education still necessary?
It is necessary. Early education experienced in infants and toddlers will enable children to develop better in the future.
There are many kinds of human memory. From the length of memory time, it can be divided into sensory memory, short-term memory and long-term memory; in addition, it is also divided into explicit memory and implicit memory.
And “memory clearing” does not mean that the baby really forgets completely, on the contrary, the memory before the age of 3 actually exists in the mind, but it cannot be extracted specifically. For example, if a baby learns to swim before the age of 3, he will “learn without a teacher” after entering the water, but it is difficult to describe the memory of swimming.
Therefore, parents should not deny early education because of the disappearance of memory. On the contrary, early education, as an implicit memory, exists in the baby’s mind and is closely related to future intellectual development. Appropriate calcium supplementation during pregnancy is beneficial to the fetus and self, but Do not pay attention to avoiding the following misunderstandings. No matter how much you add, it may be useless.

Nutrition supplementation during pregnancy can be said to be the top priority, which is related to the healthy development of the fetus. Among them, calcium supplementation is particularly important for pregnant mothers, because it penetrates all stages of pregnancy, and scientific calcium supplementation is very important.
The pictures in this article are all from the Internet , The graphic is irrelevant
Calcium supplementation during pregnancy is very important for both mother and baby. All stages of baby development require sufficient calcium to promote growth and development. The calcium of the fetus is derived from the mother, so the pregnant mother can supplement enough calcium to ensure the needs of the fetus, as well as her own needs.
Appropriate calcium supplementation during pregnancy is beneficial to the fetus and oneself.
The importance of calcium supplementation for the fetus——
Bone development and health: The fetal bones are more than 2 months pregnant. Calcification of the teeth and teeth will begin to develop rapidly at 8 months. At this time, a large amount of calcium will be obtained from the mother to ensure its development. If the mother lacks calcium, it will directly cause the fetus to have nowhere to obtain it, thus affecting Skeletal development. Perfect brain development: fetal brain development has already begun during pregnancy. The growth, metabolism, and normal brain functioning of brain cells are inseparable from calcium. Lack of calcium will affect the child’s intelligence.
The importance of calcium supplementation for pregnant women— —
The chance of hand and foot swelling is reduced: It is a common phenomenon for pregnant women to have body swelling during pregnancy. Not only can you not wear clothes and shoes that fit your feet, but also have backaches and backaches. It is most common in the third trimester. This situation has an important relationship with the lack of calcium, and enough calcium can be alleviated. The chance of cramping is reduced: the contraction of myocardium, skeletal muscle and the regulation of nerve cells are closely related to calcium. Cramps and joint pain are prone to appear when calcium is lacking. Sufficient calcium can prevent this problem. Pregnancy-induced hypertension is prevented: Studies have shown that one of the causes of pregnancy-induced hypertension is calcium deficiency. Sufficient calcium supplementation can prevent this situation.
Four misunderstandings about calcium supplementation
1) Bone soup for calcium supplementation
Many mothers choose to drink bone soup for calcium supplementation during pregnancy, but this method has no effect.
Because the calcium element of calcium is insoluble in water, the calcium content of the soup is not high. The soup made from 10 kilograms of ribs only contains 150 mg of calcium. In addition, the bone soup is simmered for a long time, and a large amount of fat is dissolved in the soup. Drinking more will increase weight.
2) Eat a variety of calcium-containing foods at the same time
It is the choice of many pregnant mothers to supplement calcium with food, and they think that one food has too little calcium supplement, so they eat several foods rich in calcium at a time. In fact, this cannot be absorbed, and no matter how much it is, it may be useless.
It should be noted that some high-calcium foods mixed with foods containing oxalic acid and other substances will affect the absorption of calcium, such as spinach (containing oxalic acid).
3) Sun exposure at home
After learning some knowledge about pregnancy, many pregnant mothers may understand that vitamin D can help calcium absorption, and sun exposure can produce this This kind of substance, some mothers are afraid of getting tanned, so they put them on the glass at home, which is totally ineffective.
4) Calcium supplement with hot milk
Milk is rich in calcium. Many mothers may not eat cold food during pregnancy and will heat the milk. However, if the heating time is too long or the temperature is too high, calcium is easily lost and may appear Calcium precipitation will affect calcium intake and also cause problems such as constipation for pregnant mothers. It is recommended to heat it to about 70 degrees.
Note: If a pregnant mother chooses to take calcium tablets to supplement calcium, she must consume milk for 2.5 hours or more before taking it.
The correct way to supplement calcium during pregnancy
Generally speaking, calcium is required at all stages of pregnancy, and the required amount is roughly based on this standard: 800 mg per day in the first trimester; every day in the second trimester 1000 mg; 1200 mg per day during the third trimester.
It is not difficult to find that as the time of pregnancy increases, the amount required is gradually increasing, and the third trimester is the stage where the amount is the largest.
The research found: 80% of the calcium in newborns comes from the third trimester.
Early pregnancy calcium supplementation: There are no special requirements in the first trimester. As long as there is no obvious sign of calcium deficiency, it can be obtained from the daily diet to basically meet the calcium needs, pay attention to sun exposure Promote calcium absorption.
Calcium supplementation in the middle and late pregnancy: Basically, extra calcium supplementation is needed in the second and third trimesters. You can drink more milk and eat some calcium tablets for supplementation. If you want to supplement, you must pay attention to simple principles. It cannot be complicated and chaotic.
At the same time, the absorption of calcium can also be promoted by exposure to the sun. Generally, it is not less than 1 hour in winter and half an hour in summer, and avoid periods of excessive ultraviolet rays.
