Although you can’t see it, you can still understand the fetus in your belly through the exquisite fetal development pictures and understand the fetal development of different pregnancy weeks.After you perceive the fetal movement for the first time, the baby’s feeling of depending on you will be more real and intimate. Whether you give your baby prenatal education or let him listen to music, your pregnancy process will become more interesting.SO, today Xiaobian and pregnant moms share super detailed fetal development through 41 weeks of illustration every week, remember to collect it ~~~
Conceive:
When you ovulate, one egg is sent into the tubal.In the next 12 to 24 hours, if a 350 million sperm (average ejaculation of ejaculation) successfully reached the tubal that successfully reached the fallopian tube and drilled into the egg, it would fertilize the eggs.Then fertilized eggs began to divide rapidly, at the same time it was sent into the uterus from the fallopian tube and continued to develop there.
3 weeks before pregnancy:
Your baby is called embryo at this stage, and it is a small ball composed of hundreds of cells that are being split quickly.The bubbles began to implant the endometrium, and this process was called bed.In the future, the part of the placenta will begin to secrete the human chorionic gonadotropin (HCG). This hormone will make your early pregnancy detection positive.At the same time, in the empty cavity that will develop into a amniotic sac in the future, amniotic fluid accumulates around the cells.During your pregnancy, amniotic fluid will always be wrapped in your baby to protect.Your small bubbles are now connected to the uterine wall vascular that can only be visible through microscope to obtain oxygen and nutrients.The placenta will not develop until next weekend and take over this important task.
4 weeks of pregnancy:
This week marks the beginning of the embryo period.From now to the 10th week of pregnancy, all the organs of the fetus will begin to develop and operate.Therefore, at this time, the fetus is the most vulnerable and is particularly susceptible to any interference that affects his development.
Now your baby is still an embryo for two layers of tissue, and all his organs and body parts will be formed by these tissues.The initial placenta cells were bed on the endometrium to transport the fetus for the fetal blood.By this weekend, the placenta began to develop gradually, and it can provide the nutrition and oxygen required for the growth of the baby.During this period, the amniotic sac that wraps the fetus will appear. Among them, the amniotic fluid will protect the baby when the baby grows and develops, and the yolk sac will create red blood cells and transport nutrients for the fetus before the placenta is played.
5 weeks of pregnancy:
The germ is growing quickly in your uterus.At this time, your baby has looked like a little hippocampus.It is now composed of three embryo -outer embryo, middle embryo, and endometry. These three embryos will form a baby’s organs and tissues in the future.Cells are differentiated to form the main organs (such as kidneys, liver), and neural tube start to develop.The nerve tube is differentiated from the upper layer of the embryo, that is, the outer embryo, which will develop into a baby’s brain, spinal cord, nerve and spine.The outer embryo will also form the baby’s skin, hair, nails, breasts, sweat glands and tooth enamel.The heart and circulation system of the fetus begin to be formed by the central germ.(In fact, in this week, the baby’s small heart has begun to divide into the ventricle, start to be beating, and can pump blood.) Middle embryo will also differentiate the baby’s muscles, cartilage, bones, and subcutaneous tissue.The third layer is the internal embryo that will form a baby’s lung, intestine, early urinary system, and thyroid, liver and pancreas.At the same time, the initial shape of the fetal and oxygen of the fetus and umbilical cord have begun to work.
6 weeks of pregnancy:
As the fetal body begins, cells that are about to form a baby’s body and organ system are about to differentiate.Now he has a small lentil -like size (4-5 mm long).
If you can see your uterine wall, you will see a big head, and your eyes and nostrils are still small black spots.There are two small shallow nests on the ears on both sides, and their arms and legs are just small buds.His hands and feet looked like a duck, with a thick sting between his fingers (toes), but it didn’t take long for the fetal fingers and toes to become more obvious.In the future, there will be some small wrinkles below the opening of the baby’s mouth (the tongue and vocal cords just start to take shape), which will develop into his neck and jaw.
Now, the heart of the fetus (it starts to differentiate to the left and right ventricles) is running about 100 to 130 times per minute, which is almost twice the number of heartbeats of your heartbeat, and his blood began to circulate throughout the body.The intestinal tract of the fetus is developing, and the small breathing passage will begin to appear in the future where it will develop.He has also begun to construct muscle fiber tissues. By half this week, he is likely to start a small limbs.However, you have to be patient: because you may have to wait until the beginning of the second trimester, you can feel the baby’s fetal movement.
7 weeks of pregnancy:
Your baby seems to have a small tail (in fact, this is an extension of the tail), which will disappear after a few weeks.This little tail is the only thing that will grow longer and smaller during the fetal development.At present, the fetus is almost 1.3 cm long, and it is as large as one mulberry.He already has the elbow joints and clearly visible fingers and toes.His head is not proper, and the two brain hemisphere inside his head is developing.His teeth and internal structure of the oral cavity are taking shape, and his ears are continuing to develop.His eyes have appeared some colors, but some are covered by eyelids.His little nose is coming out, and one day you will not be able to pinch it.His skin is very thin, and blood vessels are clearly visible.
Your baby has grown appendix and pancreas, and the pancreas will eventually secrete insulin to help digestion.His liver is busy making red blood cells. A period of intestine has begun to burst into the umbilical cord. The umbilical cord now has clear blood vessels and began to transport oxygen and nutrition back and forth to the fetus.The fetus looks like a small tail (in fact it is an extension of the tail vertebrae), but it will disappear after a few weeks.
You still can’t feel the baby’s back and forth, but your little jumping beans will move around in the wet "small home" from time to time.
8 weeks of pregnancy:
The fetus is now about 1.6 cm long, which is probably equivalent to the size of a kidney bean.Although the fetus often moves and changes, it will take a few weeks to feel his movement in the uterus.The tail of the fetus’s embryo is disappearing, the eyelids can almost cover the eyes, and the fingers and toes are longer, although it is a bit linked.The fetus’s arm has also become longer, and the hand can bend the movement in the wrist.Now his knee and elbow joints have been formed, and he can also bend, and his feet can be touched together in front of his body.With the stretching of the trunk, the fetus’s head is more upright.The respiratory tube extends from the throat to the branches of the developing lungs.The neurons in the brain have also begun to expand and connect each other to form the initial neural line.Although you may want to know the gender of your baby, but now your baby’s external genitalia has not been fully developed, and you can’t see whether you are pregnant with boys or girls.
9 weeks of pregnancy:
Your "new residents" are nearly 2.5 cm long, and the weight is very light. It is almost the size of grapes, but the basic structure of the body has been formed, and the weight will grow rapidly.He also looks more and more like a villain. The "tail" of the embryo period has now disappeared completely. The development of all parts of his body, such as organs, muscles, and nerves.
Now the fetus’s eyelids completely cover the eyes, and it is closed very strictly, and it will not open until 27 weeks.He grew his earlobe, and at the end of this week, the internal structure of the ears was about to be completed.The upper lip of the fetus is also completely formed, and the mouth, nose and nostrils are more obvious.His fingertips grew a little bit. This is where his tactile nerve development is developed.All the main joints of the fetus, such as the shoulder joint, elbow joint, wrist joint, knee joint, and ankle joint, all started movement, so that he could move his arms and calves.His heart has now been differentiated into four ventricles, and heart valve has begun to develop.The fetal genitalia has appeared, but it will not be a few weeks to distinguish gender.
10 weeks of pregnancy:
Although the fetus is still the size of a kumquat -from head to hips exceeding 2.5 cm and weighing less than 7 grams, the most critical part of his development has been completed.It is the beginning of the fetal period that is usually called.His important organs -liver, kidney, stomach, brain, and lungs have been in place, and they have begun to "work", and they will continue to develop during your entire pregnancy.His liver continued to make red blood cells.Before that, the yolk cycles were always responsible for providing nutrients to red blood cells, but now it no longer needs to be needed and has begun to disappear.
In the next three weeks, the length of the fetus will double, close to 7.6 cm.In terms of proportion, he has a smaller head than in the previous few weeks, but still accounts for about half of the length of the entire body.Due to the development of the brain, his forehead is located at the top of the head, and the high ground protrudes forward; the forehead of the raised forehead will be retracted, making him look more like a person.Every day, there are more small changes on the fetus -small fingernails, toenails, and fluffy hair like peach skin began to appear on him.Now, his fingers are completely separated; the elbows can bend and bend slightly, the wrist can move, and the hands can touch each other with both hands; his legs are also growing, and his feet may touch the front of the body.Now, he is busy swallowing amniotic fluid and kicking.
If you can see your baby this week, you can clearly see the outline of his spine through his thin skin like paper.And, his spinal nerve began to extend from the spinal cord
11 weeks of pregnancy:
Now the little guy in your stomach has been completely formed. He is about 3.8 cm long and 7 grams.His skin is still transparent, and many blood vessels are revealed.Some of his bones began to harden, his fingers and toes were separated, and he might soon be able to hold and open his fist.The fetus was busy kicking and stretching. His tiny movements stretched beautifully and stretched, as if ballet in diving.With the growth and development of his body, the movement of the fetus will become more and more powerful.With the development of the fetal diaphragm, he may start snoring.Because he is still small, it may take about a month to feel that you can feel his movement in amniotic fluid or swallowing in the uterus.
12 weeks of pregnancy:
Your baby is about 5 cm long and weighs 14 grams.His face looks more like human.At the beginning, the eyes growing on both sides of the head pulled in, moved to the face, and the ears had reached the final position.The fetus’s intestines have grown very quickly recently, and some have entered the umbilical cord, and now they are beginning to move to the abdominal cavity.The fetus’s kidneys are urine to the bladder.His nervous cells are rapidly proliferating, and nerve sympathy (neural line in the brain) is forming.Your baby may already have more reflex movements now, including sucking. If you poke your belly with your hands, he will even move, but within a few weeks, you can’t feel his activities
13 weeks of pregnancy:
Although your belly may soon become obvious, let everyone know that you are pregnant, but your baby is still very small.In fact, the length of the fetus from head to hip is only about 7.6 cm, which is almost equivalent to the size of a prawn, and the weight is only about 28 grams.Although so small, the fetus has been completely formed in your uterus, and he is more well -proportioned than a few weeks ago.In the past few weeks, his head is much larger than other parts -now his head only accounts for about one -third of his body.His miniature and unique fingerprints have also appeared, and the kidney and urinary tract are playing due.Now he starts to drain urine into amniotic fluid he has swallowed.When you enter the middle of pregnancy (4 to 6 months of pregnancy), most of the key development of the fetus has been completed, and the risk of miscarriage has also reduced a lot.
14 weeks of pregnancy:
Welcome to the second trimester! This is an important milestone during pregnancy because it marks the end of the key development period of the fetus.All the basic structures of the fetus — including internal and external -now have formed, although they are still very small.The fetus is only about 9 cm long from head to hip, which is about the size of a lemon, weighing about 42.5 grams.
The body of the fetus began to grow faster than the head, and the neck that supports the head is now clearer and obvious.This weekend, his arms have been longer, making it proportional to other parts of the body (however, his legs are not long enough to develop for a while).The fetus began to grow very small, covered with fluff, and was called fetal hair.This week, his liver began to secrete bile. This is a sign of the normal function of the liver. His spleen also began to participate in the manufacturing of red blood cells.
Your baby is still developing urine and rowed into amniotic fluid.This week, you still can’t feel the baby’s movement, but his hands and feet (now about 1.3 cm long) are more flexible and active.Because of the stimulation of the brain, his facial muscles also began to exercise, and he was able to oblique his eyes, frown and ghostly face.He can now grab and suck his fingers.
15 weeks of pregnancy:
The fetus is about 10 cm long from head to hip, weighing about 70 grams.He is now busy inhaling and exhaling amniotic fluid to help the development of lung airbags.His legs are now longer than his arms, and he can move all joints and limbs, and his hands are more flexible.The sweat glands of the fetus are appearing.Although the eyelids were completely closed, he could feel light.If you turn on the flashlight against your belly, he is likely to avoid the light source.
The taste buds of the fetus are beginning to be formed, and a study at the Philadelphia Monir Chemical Sensory Center pointed out that the fetus may taste the taste of your food.Researchers have found that the taste of pregnant women’s feeding will affect the taste of amniotic fluid.They also found that eating healthy foods during pregnancy may help your baby’s preference for foods for life.
16 weeks of pregnancy:
The fetus does not have about 11.4 cm long from head to hip, weighing about 99 grams, which is equivalent to a big Yali.In the next three weeks, he will go through a long period -double the weight, and the length of his length will increase by several centimeters.His lower limbs have become more mature.His head is more upright than before, his eyes have moved from both sides to the front, and the fetus’s ears have reached the final position.Some of his more advanced systems have begun to play a role, including his circular system and urethra.Although the fetal hair has not yet appeared, his scalp structure has begun to develop.Although he still closed his eyes, his eyeballs had been moved slowly, and he even started to have a nail.His fingers and foot nails will continue to grow throughout the pregnancy, so if he needs to cut nails soon after he is born, you should not be surprised.
17 weeks of pregnancy:
Your baby is about 142 grams now, 12.7 cm long, and the size is like a large onion.He connected the placenta’s life bond, the umbilical cord, was thicker and stronger.The fetus can move his joint and his skeleton.Until now, cartilage like rubber has begun to harden into bones.There are 300 bones (total number of bones and cartilage) when the baby is born.As the baby grows, some bones will harden and integrate together.When it grows to an adult, there are only 206 yuan.
18 weeks of pregnancy:
Your baby is about 14 cm long from head to hips and weighs 198 grams.He is busy stretching his arms and kicking, and you may feel more and more of these actions of your baby.The blood vessels under his thin skin are clearly visible, and his ears have grown to normal positions, and their edges are rising.Osomonic phospholipids -a protective effect began to be formed around the nerves of the fetus, which will continue until his birth.If you are pregnant with a girl, her uterus and fallopian tubes have been formed, and they are already each.If you are a boy, you can see his genitals, but when he is a B time, he may cover his "privacy" and let the doctor see it.
19 weeks of pregnancy:
Your baby now weighs about 240 grams and is 15 cm long from head to hip, which is about the size of a small melon.His arms and legs are now proportional to other parts of the body.His kidneys continued to develop urine, and the hair on his scalp began to grow.If you are pregnant with a girl, there are 6 million eggs in her ovaries.Now is the key period of baby’s sensory development: the fetal brain began to divide the specialized area of smell, taste, hearing, vision and touch.You may think that your uterus is very quiet. In fact, it is far from what you think. The fetus may now hear what happened around.What sound he heard? Mainly, the sound of your blood flowing through the blood vessels, the murmur of the gastric digestion, and your voice.Some expectant mothers like to speak to their babies, but even if you don’t do this, your baby can still hear you talking to others.Studies have shown that he is learning to distinguish your voice and others, and will soon show his preference for your voice.Studies also show that when a pregnant woman speaks, the baby’s heartbeat in her belly will slow down, indicating that the baby is relaxed.Let the prospective dad also participate — encourage him to talk to your baby
20 weeks of pregnancy:
Your pregnancy has gone halfway -congratulations! Your baby is about 298 grams now.The length from head to hip is about 16.5 cm, and the length from head to toe is about 25.4 cm.(In the first 20 weeks, we measured the length of the fetus from head to hip -that is, the "head and hip length" measurement method. In the future, we will measure it from head to toe.It is difficult to measure in front of the trunk).A greasy white substance is covered with the body of the fetus. This substance is called fetal sebum. It can protect the skin that the fetus is immersed in amniotic fluid for a long time.The fetus swallowed more frequently, which is very good for his digestive system.He is still making tire dung -a black, sticky substance, consisting of dead cells, digestive secretions and swallowing amniotic fluid.This kind of fetal manure will accumulate in his intestine and become the "achievement" on the first diaper after the baby is born (there are also a few babies to discharge tire dung in the uterus or when they are born).
21 weeks of pregnancy:
Your baby weighs about 340 grams now, nearly 26.6 cm long.His eyebrows and eyelids have been fully developed.If you are pregnant with a girl, her vagina is now formed and will continue to develop to birth.The fetus loves to move now.Persons who researched the fetus found that the fetus would move about 50 times in one hour, even when I was sleeping.All exercise helps stimulate the development of fetal body and intelligence.During the day, you may not be able to notice that the baby has 50 punch and kick, but when it is calm at night, if you find that your little guy seems to want to "dance" to Tianming, you don’t have to make a fuss.Why does he wait until the night comes, and when you want to take a good rest, he may be active? He may really ignore your schedule, but it may be because he is not much more moved than during the day, but you are quiet at night you are quiet at night.When it is, it is easier to notice his "fitness" activity
22 weeks of pregnancy:
Your baby looks like a "mini" newborn now, about 27.7 cm long, and nearly 450 grams.His skin was still wrinkled, and he could not support the skin until his weight increased to a certain extent.In addition, the slender hair (tire hair) covered on his head and body also appeared.The fetus’s eyes have developed, but the iris (colored part of the eyes) still lacks color.His pancreas is an important organ that produces hormones and is also developing steadily.The fetal lips are getting clearer, and the tip of the small teeth also appears in the gums, showing the initial signs of long teeth.It is not until 4 to 7 months after he is born that you will really see that he grows his first teeth, unless he is a very few babies with teeth when he is born.
23 weeks of pregnancy:
Your baby is about 28 cm long and weighs more than 450 grams.His skin is still red and wrinkled, and it is possible to become pink or reddish when he is born.The blood vessels revealed through the skin are the cause of the skin red.His real skin tone will be manifested in the first year after birth.The tissue and blood vessels of the fetal lungs are developing. Preparing for his breathing, the fetal lungs are fully developed for a few months.The lungs are the final organic organs of the fetus.Therefore, premature babies (born before 37 weeks) often have difficulty in breathing.If the baby is born this week, under strict medical care, there is still a certain opportunity to survive, but the risk of serious complications will be very high.He can swallow it now, but usually starts to defecate after birth.He can hear a lot of big noise in your uterus, such as the roar of the dog barking and the vacuum cleaner, which can help him feel free when he hear these sounds after birth.
24 weeks of pregnancy:
Your baby is growing steadily. Last week, his weight had reached 450 grams, and it increased by about 113 grams this week.He now has nearly 30 centimeters long and thinner, but his body is coordinated and grows, and soon increases more fat.The fetal skin is thin and wrinkled, translucent, his brain develops very quickly, and taste buds may also play a role now.His lungs are developing "branches" of "tree", and lung cells that are responsible for secreting surface active agents (a substance that helps lung alveoli more easily expand).
25 weeks of pregnancy:
Now your baby is about 34 cm long from head to toe, weighing about 680 grams.It sounds not very heavy, but he is no longer as long and thin as before, and it looks fuller.As the fetal weight increased, his wrinkled skin also began to open up, becoming more and more like a newborn.Now you can see the color and texture of his hair, although they may change after the baby is born.
26 weeks of pregnancy:
Your baby is less than 900 grams now, about 35.6 cm from head to toe.From now to birth, with the rapid accumulation of fetal fat, his weight will increase by more than 3 times.The fetus needs fat to help him adapt to lower temperatures outside the uterus and provide energy and calories a few days after birth.Newborn weight will decrease (sometimes 10%of birth weight), which is especially common among breastfeeding babies.The nerve conduction in the fetal ear is developing, which means that his response to the sound will be more consistent.His lungs are also developing, and he continues to breathe in the medium and small mouth of amniotic fluid. This is a good practice for his first time he breathing air after birth.If you are pregnant with a boy, his testicles start to fall into the scrotum, which takes about 2 to 3 days in this process.
27 weeks of pregnancy:
Your baby really starts to fill your uterus now.He weighs about 900 grams this week, and when his legs are straight, about 36.6 cm.Now he can open his eyes, close his eyes, and form a regular sleep cycle.He might suck his fingers.Although his lungs have not yet matured, if the baby is premature at this time, with the help of external forces, his lungs should already be able to exert their due functions.Now you may feel some rhythmic movements in the fetus, most of the cases are hiccups.From now on, the fetus will often snoring.Every time it lasts only a few minutes, he will not feel uncomfortable.Enjoy these interesting moments.With the development of more brain tissue, the fetus’s brain has become very active.
28 weeks of pregnancy:
By the week, the fetus weighed more than 900 grams, and it was about 37.6 cm from head to toe.The biggest change this week is: he can open his eyes.His eyelashes have also grown completely.If there is a long light outside the uterus, he will now turn his head to the beam.His fat layer continued to accumulate to prepare for the life outside his mother’s uterus after birth.
29 weeks of pregnancy:
Your baby weighs about 1.1 kg and is 38 cm from head to toe.His muscles and lungs are continuing to mature, and billions of neuron cells are generating in the fetus’s brain.In order to accommodate the development of the brain, the fetal head is also increasing.Due to so fast growth, the nutritional needs of the fetus reached its peak in these three months.In order to ensure that you and the fetus can get comprehensive nutrition, you need to supplement a large amount of protein, vitamin C, folic acid, iron and calcium.(About 200 mg of calcium is accumulated in the fetus every day in the skeletal of the fetus).
30 weeks of pregnancy:
Your baby is about 39.4 cm now, weighing about 1.4 kg.There are 0.85 liters of amniotic fluid around him, but as he grows up, more and more space occupies the uterus, and amniotic fluid will decrease.Your baby can now distinguish light and darkness, and he can even follow the light source back and forth.After the baby was born, he closed his eyes most of the day.When he opens his eyes, he will respond to the change of light, but he can only see things within 15-30 cm in front of his face.You might hold him very close to you, this distance can just make him see you clearly.
31 weeks of pregnancy:
Your baby is about 40.6 cm long and weighs more than 1.4 kg. He is about to experience a peak of development.The fetus can turn his head from one side to the other side. Of course, he doesn’t know that this action means "NO", but after the baby is born, you will be surprised by his understanding of this movement and other movements.He will also save a layer of fat under the skin to prepare for birth.The fat layer saved in the fetus in recent weeks can also make his arms and legs plump.
32 weeks of pregnancy:
Your baby weighs about 1.8 kg and is about 43.2 cm long.His fingernails and foot nails have grown completely.Some fetuses have grown their heads, and some only have faint fluff.Your baby now occupies a large place in the uterus, but the narrow space will not reduce his activity level.You may have heard that the babies’ activities in the later stages of pregnancy will be reduced, but this is not the case.If you notice the decrease in fetal activities, remember to go to the hospital immediately.
33 weeks of pregnancy:
Your baby is ready to come to this world! His fat layer is thickening, which will help him control his temperature after birth.Your baby may have 51 cm long, weighing 3.2 kg (boys are often heavier than girls).The baby’s organs have been fully developed, and each is in place.His outer skin is falling off, replaced by the new skin below.
34 weeks of pregnancy:
Your baby has been fat.He may now weigh 2.7 to 3.4 kg and 48.3 to 50.8 cm long.His grabbing is already very powerful, and soon you will notice this when his little hand is grasping your fingers! His organs have been fully developed and each is in place. His lungs and brains are enoughPlaying functions, but they will continue to develop throughout their children’s childhood.
35 weeks of pregnancy:
Your baby is getting bigger and bigger.He weighs about 2.3 kg and is about 45.7 cm long.Because your uterine space is getting smaller and smaller, the fetus is no longer floating in amniotic fluid, and it is unlikely to turn over.But smaller space does not mean that his activities will be reduced, and the frequency of fetal activity should be the same as before.His kidneys have been fully developed, and the liver can metabolize some waste.Now, the baby has completed most of the body’s development, and in the next few weeks, his weight will continue to increase.
36 weeks of pregnancy:
The weight of the fetus continues to increase, an increase of about 28.3 grams a day.Now he weighs about 2.7 kg, almost 49 cm long.The fluff covered with the whole body of the fetus and the fetal fat that protects the fetal skin in amniotic fluid is beginning to fall off.The fetus now swallow these shed substances and other secretions, and they will accumulate in the baby’s intestines until he is born.This black mixture is called fetal manure, and it will become the first feces of the baby after birth.
By this weekend, your baby is full (the baby born at 37-42 weeks is a full moon baby, the baby born 37 weeks ago is a premature baby, and the baby born after 42 weeks is an expired child.) The fetusThe current posture is likely to be rushing down. This is the most ideal posture of delivery, but if you wait for next week, if your baby has not turned his head down, some doctors may suggest that you do "abreast of the fetal position".That is, under B -ultrasound monitoring, the fetus is promoted by the outside of your abdomen to change the position of the fetus.
37 weeks of pregnancy:
Congratulations! Your baby is now full -moon -this means that the baby has been fully developed and prepared for his life outside the uterus.Your baby now weighs more than 2.7 kg, from head to toe 48.3 to 50.8 cm.
Many babies have long hair when they are born.There are also some babies who have almost no hair, or only a faint fluff.
38 weeks of pregnancy:
Your baby has been fat.He may now weigh 2.7 to 3.4 kg and 48.3 to 50.8 cm long.His grabbing is already very powerful, and soon you will notice this when his little hand is grasping your fingers! His organs have been fully developed and each is in place. His lungs and brains are enoughPlaying functions, but they will continue to develop throughout their children’s childhood.
39 weeks of pregnancy:
Your baby is ready to come to this world! His fat layer is thickening, which will help him control his temperature after birth.Your baby may have 51 cm long, weighing 3.2 kg (boys are often heavier than girls).The baby’s organs have been fully developed, and each is in place.His outer skin is falling off, replaced by the new skin below.
40 weeks of pregnancy:
Now it is difficult to accurately say how big the baby will be when it is born, but usually, the average weight of newborns is more than 3 kg, and the average growth is about 50 cm.Over time, your baby will grow up, and his nails and hair will continue to grow.The bones on the baby’s head have not been connected together. In fact, this situation will be maintained until the baby is born. This is to make the baby’s head more easily squeezed during childbirth to successfully pass the production channel.One year or longer after the baby is born, you can find these soft parts on your baby’s head. This is the "braised door".
41 weeks of pregnancy:
The baby is about 50.8 cm long now.He is still growing, and he weighs almost 3.6 kg.Although it is very comfortable to stay in the mother’s uterus, the baby cannot stay inside forever.Considering the health of the baby, if he is not born next week, the doctor will suggest that you induce labor, or if there are any other problems, the doctor will have more time to induce labor for you early.Most doctors will not allow you to give birth only after two weeks after the due date, because it will increase the probability of you and your baby suffering from various complications.However, there are 5%to 6%of expectant mothers, and they will not give birth until 3 weeks later than the due date.Babies born in the 42nd or later, their skin may be as dry as sheepskin paper, and they are usually overweight.In addition, late birth will increase the chance of uterine infection, which is very dangerous to the baby and even cause death.Not only that, late production is also very likely to extend or terminate the childbirth time, thereby increasing the risk of injuries during vaginal delivery in the process of vaginal delivery. The probability of accepting a caesarean section will also be doubled.
Xiaobian 即: Even in the uterus, the development of each baby is different.What we are talking about now is only about the development of the baby.
