Is the fetus face to face with its mother in the belly or behind its back?

When the first feeling of fetal movement, pregnant mother will think of a question, which part of the baby is the bulge on the stomach? Feet or back? Fetal baby in the mother’s belly, is face-to-face with the mother, or carrying it? Let’s find out! < / P > < p > to answer this question, first of all, it depends on the gestational age. When the gestational age is still small, the fetus in the mother’s stomach is just like in a swimming pool. It’s face-to-face with you today and back to you tomorrow. It’s not going to stay in one direction. Small gestational age baby is floating in the amniotic fluid in the womb, while the large gestational age fetus, generally to 34 weeks or so, posture can not have too much change. < / P > < p > whether it is head position or breech position, the fetus may be face-to-face with the mother, but for natural birth, it is better for the baby to face the mother, that is, occipital anterior position. < / P > < p > the baby’s face will now face your back, and the back will slightly face your abdomen. This position is called occipital anterior position, which is the ideal position for the baby to pass through the pelvis – he can plug his chin in his chest to fit through the pelvis, and turn slightly to the birth canal during delivery. Most babies use this position. < / P > < p > when some fetuses enter the basin, the back of the brain is facing the mother’s spine, and the face is facing the mother’s abdomen. Only about 5% of the fetuses can not change to the occipital anterior position. In this position, the baby is unable to properly press the chin to the chest, and most of them will be further straightened through your pubic arch. This kind of fetal position will lengthen the labor process, make you backache during childbirth, and may need more auxiliary production. < / P > < p > now you know, the fetus is in your stomach, most of the time is a little naughty, the body is constantly moving. Do you know that the fetus is not moving aimlessly? Let’s learn more about the secrets of the fetus! < / P > < p > If Mommy thinks the womb where baby lives is a quiet place, it’s a big mistake. The average volume in the uterus is 85 decibels. This volume is like a busy road, very noisy. This volume through the amniotic fluid to fetal baby’s ears, still can reach 60 ~ 75 decibels. It’s also the volume of a normal conversation or a vacuum cleaner at work. It can be seen that the baby in the womb is surrounded by “noise” most of the time. < / P > < p > fetal baby’s auditory nerve began to develop gradually from 6 weeks of gestational age, the morphology of cochlea and the differentiation of auditory nerve were basically completed around 24 weeks, hearing began from 15 to 20 weeks, almost equal to that of adults by the 25th week, and had full response ability to acoustic stimulation by the 28th week. < / P > < p > because the uterus is not an airtight sound barrier, people’s voice can be transmitted into the uterus. Therefore, in the last three months of her life, the baby often eavesdrop on her father and Mommy, and can distinguish their voices. Before the voice of Mommy is transmitted to the baby, it will be filtered by layers of trachea, muscle, bone, amniotic fluid, etc., so that the baby can remember the voice of mommy from the strength of voice, the height of intonation and other contour features, and distinguish it from other women’s voices. < / P > < p > the earliest development of fetal baby is touch. Because the dark intrauterine environment limits the development of vision, so the baby’s touch and hearing are more developed. In the second month of pregnancy, the baby can twist her head, limbs and body; in the fourth month, when Mommy’s hand touches the baby in her abdomen, she will frown and squint. If Mommy puts a little pressure on her abdomen, she will immediately give her hand or foot back. Some people observed through fetal endoscopy that when touching the palm of the baby’s hand, he immediately clenched his fist to make a response; when touching his lips, he raised his small mouth to make a sucking response. This also shows the existence of fetal baby tactile function. < / P > < p > the “taste buds” used to feel the taste gradually form at the third month of pregnancy, and have been fully developed at the fourth month. The fetal baby can distinguish sweet and bitter at about seven months, and most fetal babies tend to like sweet. < / P > < p > in the second half of pregnancy, the baby drinks about 1 liter of amniotic fluid per day on average. In addition to water, amniotic fluid also contains urine, salt, sugar, fatty acid, cholesterol, etc. Although the amniotic fluid is slightly salty, fetal baby can still taste it with relish. However, the taste of amniotic fluid changes with the diet of pregnant mothers. Fetal baby will determine whether to swallow or not, or how much to swallow by distinguishing the taste of amniotic fluid. The 7-month-old baby sucks the sweet amniotic fluid and spits out the bitter amniotic fluid. If the pregnant mother doesn’t eat spicy food at ordinary times, but occasionally has a very spicy meal, the baby will even make faces to express her dissatisfaction. < / P > < p > it is precisely because the fetal baby’s taste system has been formed in the early stage, so the baby after birth can immediately distinguish between breast milk and other taste differences. < / P > < p > sucking fingers is just an instinct. Because all the nutrients needed in the development of fetal baby are directly transmitted through the umbilical cord, there is no need to have feeding technology in the uterus. But the baby needs to spend a lot of time sucking her thumb, which is ready for the baby to eat mommy’s milk in the future. And finger sucking can help baby find interesting things in her body, such as the feeling of her skin and the size of her thumb. Therefore, the behavior of sucking thumb in the womb is also the beginning of exploring the world. < / P > < p > babies cry a few weeks before they are born, mostly at the end of pregnancy or before labor. Some babies cry weakly, showing a slight low cry; some babies cry loudly. There are many reasons for crying, but the main reason is that the baby feels uncomfortable in Mommy’s womb, even caused by dangerous omens. < / P > < p > the baby is often photographed smiling, experts believe that this is an emotional or physiological reaction, which is to help the baby adapt to the outside world after birth. < / P > < p > but why doesn’t the baby smile in the weeks after birth? This may be because the baby is carefree and undisturbed in the womb, showing a smile when she is in a happy mood. However, babies are exposed to a new and strange environment within a few weeks after their birth, which is more challenging than in Mommy’s stomach, and may even make them suffer some “trauma”, so they won’t “laugh happily” for a period of time. < / P > < p > in fetal baby’s senses, visual development is the latest. Probably because it’s very safe in Mommy’s womb, there will be no threat of natural enemies, so it’s unnecessary for baby to visually identify the shape of objects. < / P > < p > in Mommy’s stomach, the baby can only feel the light and dark changes at most. In the dark, the inside of the tire is completely dark, and in the daytime, the light is also very dark, which is equivalent to the brightness of indoor night lighting. When a beam of light shines on mommy’s abdomen, the baby who opens her eyes will turn her face to the bright place and see a red halo. < / P > < p > fetal baby will also have his living habits, mainly in the alternate cycle of sleep and awakening. Because weak light can improve the activity of fetal baby brain. Therefore, although living in the dark womb, the baby can judge whether it is night or day by the faint light changes she feels, and begins to spend a 24-hour cycle of regular life with her mother. < / P > < p > If a pregnant mother likes to stay up late, go to bed late, and get up late the next morning, not only can she not adjust her “biological clock” well, but even the baby’s “biological clock” can’t operate normally in a 24-hour cycle. Irregular life is very bad for the body. The “biological clock” of brain, heart, liver, kidney and other organs will be disordered, and the balance of the body will be destroyed. Therefore, for the health of the baby, the pregnant mother must live regularly. < / P > < p > fetal baby’s nose begins to develop as early as the second month of pregnancy, and by the seventh month, the nostrils can communicate with the outside world. However, because of being surrounded by amniotic fluid, fetal baby’s olfactory function can not be greatly developed. It is not until after birth that the baby’s sense of smell begins to show its power, ensuring that the baby can recognize the smell of mummy when feeding, and that it can be recognized as soon as the baby approaches mummy in the future. < / P > < p > when the baby grows up in the mother’s stomach to be able to be born, it will send out hormone signals. The mother who receives this signal will make the hormone that makes the uterus contract strengthen, and the pregnant mother will suffer from frequent labor attacks. < / P > < p > when Mommy’s uterus contracts strongly, the baby is forced to move in the direction of the birth canal. In the process of production, every contraction of Mommy will squeeze the baby’s brain and lung rhythmically, which will promote the maturity of the baby’s brain and lung. In the process of the gradual expansion of the uterine orifice, most babies make the right action: turn the head, bend the body, and turn to the pelvis like a screw. < / P > < p > when the uterine orifice is opened to about 10 cm, the baby’s head will move towards the vagina through the uterine orifice. After that, the baby took the regular labor wave, turning in the narrow vaginal birth canal, while continuing to decline. At this time, the baby is very active, trying to cooperate with Mommy, in the birth canal as soon as possible to find the biggest space way out. < / P > < p > the fetal baby living in the amniotic cavity does not have his own breathing, and the strong skin stimulation received by the fetal baby when passing through the birth canal will wake up the respiratory center of his brain, so that he can start to prepare for lung breathing. After a lot of hard work, the baby’s head finally rushed out of mummy’s body, contacted the air and began to breathe for the first time. However, the midwife would not let the baby breathe prematurely before cleaning up the amniotic fluid and mucus in the baby’s upper respiratory tract. With the delivery of the head, the other parts of the body (shoulder, trunk, buttock, lower limbs) have been delivered, baby began to live independently. < / P > < p > newborn babies will express their feelings by crying, keep moving their arms and legs, and gradually adapt to the new environment. Mommy can be relieved to hear the full cry of Zhongqi, which proves that baby has established normal lung breathing. So, next baby will start his new life! Focus
