/kloc-What is the pregnant baby doing in the mother's belly during 0/0 month?

In fact, in the long ten months, the fetus slept most of the time. Everything around the fetus is dark. He often closes his eyes and falls asleep with his mother's heart beating. Fetal sleep can be divided into quiet type and active type. During the whole pregnancy, quiet sleep accounts for about 20%, active sleep accounts for 60% ~ 70%, and the rest is awake time. The fetus under active sleep will have involuntary stretching, hand and foot movements, and the date will last for 40 minutes. At this time, as long as the mother shakes her body, she will be awakened. The fetus who sleeps quietly has no obvious fetal movement, and its heartbeat is relatively stable, lasting about 20 minutes. At this time, he is not easily woken up.

2. Swimming and stretching

As long as he doesn't sleep, he is an energetic and mischievous little guy, wandering around, stretching his muscles, sucking his fingers and even biting his little feet ... In fact, he started swimming in his mother's womb before he could be called a "fetus". This aimless swimming has no posture at all, like a leisurely little seahorse. This activity lasts from the sixth week of the baby to the late pregnancy until he is too old to float in the amniotic fluid. He can move his arms freely, bend his fingers and toes, bend, stretch and turn his palms, wrists, legs and toes. By the end of pregnancy, his bones are getting harder and harder, and he will often turn over, kick, shake hands and spread his hands. The pregnant mother will feel the fetus sliding on both sides of his waist. This is the fetus moving, moving.

Four modes of fetal movement

Theoretically speaking, there are generally four modes of fetal movement in infants, as follows:

1. Whole body movement: the movement of the whole trunk, such as turning over. This kind of exercise is intense, and each action lasts for a long time, usually 3 ~ 30 seconds.

2. Physical exercise: stretching your arms and twisting your body. The duration of each action is generally 1 ~ 15 seconds.

3. Lower limb exercise: that is, the baby kicking exercise that we often feel. This movement is fast and weak, and the duration of each fetal movement is generally within 1 second.

4. Chest wall movement: it is short and weak, and it is not easy for mother to feel it.

Yawn, swallow and suck

Pregnancy 1 1 week, the fetus in the abdomen has undergone tremendous changes. His heart began to supply blood to all internal organs and exchanged blood with embryos through umbilical cord. This is an important milestone in the process of fetal growth, and he also learned some new skills-yawning, sucking and swallowing.

The fetus yawns like us, and his mouth is wide open, but we don't know whether he yawns because he is sleepy or tired. Fetal nutrition is transmitted through umbilical cord, and his swallowing is of little significance to nutrient supply, just a cycle of amniotic fluid. Amniotic fluid has become a toy for the fetus to go in and out, swallow and play, perhaps just like blowing bubbles!

Finger sucking is an instinct of the fetus, which not only prepares him for his first meal after birth (the newborn knows how to suck as soon as he touches the nipple, and the sucking reaction is one of the most important survival skills of the baby), but also helps him discover interesting things on the body, such as the feeling of skin and the size of his thumb. Therefore, the behavior of the fetus sucking its thumb in the womb is also the beginning of exploring the world.

Play with umbilical cord

Besides sleeping, the fetus likes to play, but in his mother's womb, he doesn't have any toys, and the only thing worth mentioning is the umbilical cord. It was originally a passage for mothers to deliver nutrition to the fetus, and the fetus regarded it as a "toy" by the way, circling around the umbilical cord and playing with it. Take a rest when you are tired of playing. When you are full of energy, you will play harder and harder, but you don't know that there is danger lurking here. In the process of playing, some fetuses are entangled in the umbilical cord, which leads to danger.

burp

Can the fetus burp? It sounds like a joke, but it's true. Pregnant mothers will find rhythmic fetal movements in the late pregnancy, which will appear several times a day. From a medical point of view, this is the sound made by the baby when swallowing amniotic fluid, and it is also that he is "practicing" breathing movements to make the lungs mature faster, so the fetal hiccups are not really hiccups.

pee

Will the fetus pee in the mother's womb? This is not particularly clear to many people. Studies have shown that the fetus actually urinates in the mother's womb. The fetus grows up day by day in the womb, and the most important thing every day is to swallow amniotic fluid. Research experts believe that fetal urination itself is a physiological process and an essential function for growth and development. If the fetus just swallows amniotic fluid without discharging it, it is like filling a balloon with water, which will eventually burst. After the second trimester of pregnancy, the amount of amniotic fluid largely determines the urine volume of the fetus. So there must be something wrong with the fetus not urinating. If your amniotic fluid is less than normal, you should consider whether there is something wrong with the fetus' kidney, especially the urinary system.

7. Feel the light outside

Many people think that the uterus in abdominal cavity is dull. Because, in addition to amniotic fluid, there is a layer of chorion, uterine wall and abdominal wall. The fetus living in amniotic fluid is in the dark and can't see anything. Studies have shown that the fetus is not blind in the mother's womb. In the second month of pregnancy, fetal eyes have begun to develop, and in the fourth month, they are very sensitive to light. Research experts also found that newborn babies can only see objects in the range of 30~40 cm, which is just similar to the position and length of the fetus in the uterus, indicating that newborn babies still maintain the habit of living in the uterus. Therefore, when the weather is fine, pregnant mothers often go for a walk outside to let the fetus "see" the outside world.

8. Listen to the outside world

The fetus is very clever. By the time he was 24 weeks old, he could already distinguish different voices from the outside and inside of his mother's body. Therefore, pregnant mothers should talk to the baby as much as possible and pat the baby's stomach as much as possible. It would be better if she could play some beautiful music, because the heart rate of the fetus will increase after hearing it, and it can also move with the rhythm of the music.

Usually, the fetus's hearing will be more acute in 32~35 weeks, when it will turn its head to a certain sound source. The most attractive thing to the fetus is the mother's voice, so the newborn can hear the mother's voice from everyone. If pregnant mothers listen to the same music every day, it will be more conducive to the growth and development of the fetus.

The fetus does a lot of things in the mother's stomach. In the eyes of pregnant mothers, every activity or change of the fetus is so fresh and incredible. Appreciating these activities and reactions of the fetus carefully is the happiest memory of every mother during pregnancy. In fact, most of the activities of the fetus, including the increase of heart rate, are related to certain feelings such as voice, abdominal touch, light change, etc., and all kinds of experiences of the fetus in the womb are very important for his intellectual development and emotional development.
