Now I'm just a fertilized egg who knows nothing. After three or four days of exercise, I arrived at my destination-my mother's womb. There, I quietly waited for my mother to supplement my nutrition.

Second week

I am a little older than last week, but my confused mother may not even notice my existence. I think my mother will know when I am older.

Third week

It's strange that I feel a little fat, but I'm still so light, only about 1500 micrograms, and my body is only a few millimeters.

Fourth week

I feel more secure in my mother's womb. I often sleep, and I find that some parts of my body are slowly splitting. Part of them formed my brain, the other part formed my nervous system, and I became more sensitive than before. At this time, I need all kinds of nutrition, and I have been expecting my mother to cook more delicious food for me.

Fifth week

This week, the layer of cells between the inner and outer layers of my blastoderm also grew well, so that all three germ layers forming my body were completed. In short, this week, although my body is still very small, at least I can see how long it is. I think it's about 5 mm, the size of an apple core. Some people say that I am like a little seahorse at this time. Is it really that ugly?

Sixth week

This week, I am growing rapidly. Listen, bang, that's my heartbeat, which proves that my vitality is getting stronger and stronger. During this time, my kidney and heart began to develop, and my neural tube began to say hello to my brain. The basic organs on my face have also begun to take shape, and I can clearly see my nostrils.

Week 7

Now I am like a bean about 13mm long. My facial organs are more obvious than last week. My eyes are two funny and obvious black spots. Noses open and close, ears are obviously sunken. My hands and feet are beginning to grow. They look like two cute little paddles.

Week 8

I grew up again this week. I grew to 20 mm long. Now I am a little bigger than before, like a grape. My fingers and toes have grown more and more beautiful, but there are still some webbed things between my fingers. I think they will disappear after a while. During this time, I tried to absorb the nutrition my mother gave me, so I grew very fast. Maybe I'm so happy that I've been beating secretly.

Week 9

Now it can finally be officially named fetus, because my appearance has begun to take shape. First of all, I have grown to about 25 mm, and my muscles, organs and nerves are in place. The blood vessels on my skin became clearer, my skull began to calcify and my embryonic tail miraculously disappeared.

Week 10

I'm growing fast every day. This week, my body length will reach about 40 mm. Now I am like a pod. My wrist is not only beautiful, but also can be bent as needed, and the contours of my fingers and toes are becoming clearer and clearer.

The first 1 1 week

Ha, I grew to 50 mm-60 mm this week, and my weight also increased greatly, reaching14 g. I found that even my nails and hair began to develop, and the outline of my spine was also formed. Maybe mom can see these through special instruments, and she will be happy for me.

Week 12

Celebrating the three-month birthday has begun to take shape. Now, my brain is very big, accounting for almost half of my whole body. My body length is about 65 mm, my fingers and toes are completely separated, and my bones have become harder. I feel much stronger.

Week 13

Now my face looks like a real child. My body length is about 70 mm, and my eyes stand out on my face. I am becoming more and more sensitive. At the slightest sign of trouble, my fingers will be pinched into fists and my toes will often bend. But because I am so young, my mother can't feel my movements. All she knows is that I am crawling slowly.

Week 14

My body length can reach 100 mm at most this week. I also have a fingerprint ring on my finger. Besides, I think I'm starting to pee. what can I do?

Week 15

In these few weeks, I feel that my growth rate is faster than at first. My body length can almost reach 12 cm, and my hair is beginning to increase. A thin layer of fluff has appeared all over the body, and beautiful eyebrows have grown above the eyes. I feel a little bored during this time, so I often suck my thumb, and sometimes I secretly make faces or frown.

Week 16

This week, I found that my legs are longer than my arms and my fingers are more flexible. My secret parts have also developed more clearly, and my mother can already see whether I am a man or a woman through B-ultrasound. By the way, I forgot to mention that I burped this week.

Week 17

My length is about 13cm- 14cm, which looks like a pear. This week, I suddenly found a new toy-umbilical cord. I often like to pull by hand. Sometimes it's tight, but don't worry, mom. I know how to be measured. I always let go at critical moments.

Week 18

Now my body length is close to 14 cm, and almost all my bones are rubber-like cartilage. When I move, it's like dancing in a sponge.

Week 19

I'm practicing breathing, and my chest bulges from time to time. This week, my mother can see my interesting movements through B-ultrasound.

Week 20

I naturally grew up again this week. My body length exceeded 16 cm, and my sense of smell, taste and touch began to form.

Week 2 1 week

There is a thin layer of slippery thing on the surface of my body. I know it is a special substance that can protect me from harm.

Week 22

I gained weight again. Now it weighs about 350 grams. There are clearly visible nails on my fingers. At the same time, my listening has been greatly improved. I can hear my mother's voice and music. I really like listening to my mother's voice, but what I like best is my father's rich voice. It would be better if you could tell me a story.

Week 23

Now I am a mini baby. But my skin is still red and wrinkled because the subcutaneous fat has not yet been produced. Since this week, my eyesight has been poor, and tooth germs have begun to develop.

Week 24-25

My hearing is getting better and better. I can hear my mother's heartbeat and growling in her stomach. My sense of taste has also begun to form. Do you know that?/You know what? Do you know that?/You know what? Like most babies, I like sweets.

Week 26-27

My weight has reached 800 grams, subcutaneous fat has begun to appear, and my eyes can be opened.

Week 28-30

During this time, my weight can reach1500g, so I look fatter than before. My eyes are getting better and better. I see where it is brighter. In addition, my gender characteristics have become more obvious. Because my body is getting bigger and bigger, I often change my posture, sometimes my head is down and sometimes my head is up.

Week 3 1-33

During this time, my weight has increased rapidly, and my length can reach nearly 48 cm. The wrinkles all over the body are also much less than before. My organs are basically well developed and have grown a fetal hair.

Week 34-36

In the past few weeks, my weight can reach about 2400 grams. I'm going to be born, and my head has fallen into my mother's pelvis. At the same time, my kidney is fully developed and my liver is working.

Week 37-39

I'm so happy that I'm finally born! At this time, my weight is close to 3300 grams, my hair has grown a lot, the original layer of fluff has disappeared, and my skin has become so smooth.

Week 40

I don't want to stay in it anymore, because the fluff and secretions on my body make my amniotic fluid turbid and my hands and feet uncomfortable. The place is too small. Come on, come on, let me get out of here, I want to see my mother as soon as possible!

When a mother carries out prenatal education, she should cooperate with the physiological maturity of the fetus in the uterus. It can be roughly divided into the following stages: when the fetus is 2 months old, the fetal spine has formed and his skin has a "feeling". At this time, the mother can convey her feelings for the baby by touching her stomach and taking a walk to promote uterine contraction.

When the fetus is 3 months old,

The fetus will suck fingers or umbilical cord and arms, and the ability to suck indicates that the fetus has the feeling of skin. At this time, his brain also developed, but how to increase the multi-network connection of brain axons and become a smart baby depends on the pregnant mother's next efforts in prenatal education.

When the fetus is 4 months old,

Fetal hearing has been formed, you can hear sounds outside the uterus, so this is the best time for music prenatal education, but pregnant mothers should avoid violent and noisy sounds so as not to scare the fetus, and pregnant women should be able to feel fetal movement during this period.

When the fetus is 5 months old,

At this time, whether the mother reads the voice to the baby or talks to him, it can make the baby write it down, feel safe and calm down.

When the fetus is 7 months old,

He can distinguish between high and low pitch, clearly reflect "like" or "dislike", so that his mother can understand the reaction of the fetus in the abdomen. His retinal cells are completely formed, but the fetus does not open his eyes to see, but distinguishes day and night through his mother's body. This is because the "pineal hormone" in the human brain is at work.

When the eyes receive light, they will secrete less hormones. On the contrary, when the eyes receive dark, they will secrete more hormones, and the signals secreted by the mother will be transmitted to the fetal brain. The normal work and rest of the pregnant mother is very important. Fetuses who go to bed early and get up early will be more active and healthy than other children.

When the fetus is 8 months old,

The taste system is perfect. After 8 months, the fetus has been able to respond to the mother's emotions. In fact, from the pregnant mother's pregnancy, the baby's emotions are closely related to the mother's own feelings. The mother's pregnancy in October has been separated from the fetal feelings and love for life.
