The little baby was just over ten days old and has very delicate facial features. He must be a big beauty when he grows up. No wonder his father is so happy. He shows the baby to others every time he sees a guest, for fear that others will not see his baby daughter.
One of the relatives took the baby's hand. The baby was also very strong and shook it back hard. Then the relatives said magically: Oh, the baby likes me. You see she held my hand so hard, and she couldn't even shake it. Haha, you, a father, are going to lose favor!
In fact, this situation occurs in newborns, because the baby is born with magical functions. We call these magical functions original reflection .
1. What is original reflection?
primitive reflex is a congenital reflex that is present in the newborn, which refers to the newborn's brain stem that controls its automatic or stereotyped actions. It is an instinctive action and does not require the newborn to have an independent consciousness.
For example, the baby will eat milk at the first time and will "walking" at the first time. There are also statements about these reflex behaviors in the newborn in " American Academy of Pediatrics Encyclopedia ": Most of the physical activities of the newborn in the first few weeks are ejaculation behaviors, which means that he is instinctively active, not deliberately. Some reflex behaviors will remain for months, while others will disappear within weeks.
At the same time, the original reflex can also reflect whether the baby's body is healthy or whether the nervous system 's function is normal.
. After a period of time, will develop with the development of the central nervous system of the baby , and these innate reflexes will gradually disappear. If they have not disappeared at a certain time, parents should pay attention to the baby's nervous system problems.
2. What are these reflection behaviors?
The first type is milk search reflex
, which is the behavior of the baby to automatically find the source of milk. When we touch the baby's small face or lips with our hands, the baby will look for the nipples.
So even if we don’t deliberately help the baby with milk, as long as we are close enough, the baby can find the milk source by himself.
▶Breast search reflex will appear when the baby is born and disappear when the baby is about 4 months old.
The second type is sucking reflex
that is, as long as you put the pacifier or nipple, or even clothes into the baby's mouth, the baby will start sucking without any guidance.
So we can see that even if the baby is born with his eyes closed, as long as the mother breastfeeds, the baby's small mouth will squeeze and squeeze.
, but at the beginning, the business was not proficient enough, and the movements such as sucking and swallowing were not coordinated enough. As the number of times of breastfeeding increases, the baby can master the skills.
▶ Unlike other reflex behaviors, the sucking reflex begins during pregnancy. Pregnant mothers who have not yet given birth can take a sneak shot when they have a B-ultrasound, and maybe they will find that the baby is sucking his fingers. This reflex behavior of the baby will disappear around 3 to 4 months of birth.
The third type is shock reflex (moro reflex)
That is, when the baby suddenly changes his posture or is subjected to other stimulation, the baby will stretch his arms, legs, and neck, and then quickly retract his arms and hug him in front of him.
It seems that the baby is scared, and many babies cry because of this reflex when they are placed in the bed or are sleeping.
▶Shock reflex is very common in the newborn period and usually disappears after the baby is 2 months old.
The fourth type, step reflection
If I say, newborns are born to walk, do you believe it?
can’t help but you don’t believe it!
In addition to being born to be able to eat milk, newborns are also born to walk. This is because newborns have their own step reflex.
That is, when we pick up the baby, help him support his body, and then let the baby land his feet on the table, the baby will start to walk.
▶ Step reflex is a reflex behavior brought by a newborn when it is born and usually disappears when the baby is 2 months old.
The fifth type, ankylosing neck reflex
ankylosing neck reflex is more interesting, that is, when the baby's head turns to one side, the arms on the same side will be straightened, and the arms on the other side will be bent.
However, this reflection is not very conspicuous, so many parents don’t care, or they don’t know its existence.
▶The ankylo neck reflex appears when the baby is born and usually disappears when the baby is 5-7 months old.
The sixth type, grip reflex (grasp reflex)
This kind of reflex is easily seen in newborns. Whenever we see a newborn, we can't help but lift the baby's hand, and then the baby will quickly grab our fingers and wrap the fingers tightly in his palm. At the same time, we can also feel that the baby has a considerable grasping force.
▶ Grasp reflex also appears when the baby is born and usually disappears when the baby is 5 to 6 months old.
The seventh type, foot grip reflex
Foot grip reflex is actually similar to the previous one, that is, when someone scratches the soles of the baby's feet, the baby's toes will curl up tightly.
is just because the toes are shorter than the fingers, which looks a little different from the grip of the hand.
▶The time when the foot grip reflex appears is when the baby is born and disappears is about 9 to 12 months.
As mentioned above, these reflex behaviors of the baby reflect the baby's neurodevelopment. If it exceeds the time it was originally about to disappear but has not disappeared, it is related to the baby's brain development. It is best to take the baby for examination in time.
