How did the baby develop in the first three months of the baby’s life?

“The moment I saw the pregnancy test stick was two lines, I found that I became a mother. It was really the happiest moment in our lives!” Like your mother, we are looking forward to the arrival of new life. Presumably the mother must be curious, how is the baby’s growth process in the belly?

Week 1:
The baby is now a round ball. The current diameter is only about 150 μm (μm = micrometer, 150 μm = 0.015mm). Mommy can’t see it even if it has large eyes, it is really small! She (egg) is waiting for a little tadpole to appear, Xiao Yan ~ Where are you? If you don’t meet her anymore, she will be excreted in the body!

The fetus is long: Now the baby is still a small cell, and the mother has to wait to observe it!

Fetal weight: Now the baby is still a small cell, and the mother has to wait to observe it!

Week 2:
Little tadpoles finally come! This group of “fine” Ruishe troops must pass the test first, and they must also grab the first and get the top spot in order to meet the cute eggs!

Fetal weight: Now the baby is still a small cell, and the mother has to wait to observe it!

Week 3:
The baby is starting to perform complex cell division now, and at the same time, he must quickly find a place to foil, move along the cilia on the fallopian tube towards the uterus, and get giving birth to the baby’s warm home. Mommy’s uterine wall blood vessels will be thickened at this time, making the baby feel more comfortable to lie on it! The baby looks like a “mulberry” now, that is, the so -called “embryo”!

The length of the fetus: about 0.025 cm.

Fetal weight: The baby is still very light, and the mother has to wait to observe the baby’s weight!

Week 4 (first month):
At this time, all the organs of the baby began to develop and operate, and the placental tissue was formed at this time. Placental cells will be cut to open the channel to the inner layer of the uterus so that the blood of the mummy can flow in, so that the baby has nutrients and oxygen grew up. And the “amniotic sac” is also developed at this time, which can provide baby protection and grow peacefully.

The length of the fetus: about 0.1 cm.

Fetal weight: The baby is still very light, and the mother has to wait to observe the baby’s weight!

Week 5:
The baby now lives in a transparent water ball, which allows the baby to float easily. In addition, there are more things like suction cups (placenta), and a line (umbilical cord) like a telephone line (umbilical cord), which is tightly connected to the mother. The placenta is the source of nutrition to the baby for the baby. It is responsible for transporting oxygen (nourishing) jobs. The waste in the baby will also send it back to Mommy. These two roads are separated, so they will not be confused!

The length of the fetus: about 0.3 cm.

Fetal weight: less than 1 gram.

Week 6:
The baby’s heart began to grow, divided into the left ventricle and the right ventricle, and what is even more exciting is that the mother can hear the baby’s heartbeat through the ultrasound! The frequency of the baby’s heart beating is 100 to 130 per minute. The body slowly begins to take shape, about the same as a lentils!

The length of the fetus: about 0.6 cm.

Fetal weight: less than 1 gram.

Week 7:
The baby starts to develop facial features this week! There are two black protrusions (eyes) on the baby’s face, but the distance is a bit far away, and there are two small black holes (nostrils)! A piece of semi -circular meat grows around the neck, which is the structure that forms an external ear in the future. Can you hear the voice of Mummy’s speech soon after? The baby’s body also has wonderful changes. There are 4 places like the plants germinated with things (limbs), and the tail that was originally like a small fish also slowly disappeared. The baby is developing the nervous system that allows the baby to see and hear, as well as the liver and the stomach.

Fetal length: about 1 cm

Fetal weight: less than 1 gram.

Week 8:
Last week, my body germinated 4 places, and this week became even more different! At the front of the “bud”, there seems to be five small circles; the two black protrusions on the baby’s face are protected by a thin layer of skin (eyelid). And the baby already has two layers of skin, thin and transparent skin, you can clearly see the blood vessels, and the skin’s hair follicles have begun to grow hair! In addition, if the baby is a younger sister, the ovarian reproductive organs are also formed; if the younger brother, the testicular reproductive organs will also begin.

The length of the fetus: about 1.5 cm.

Fetal weight: about 1 gram.

Week 9:
The current baby is about the same size as a grape. The basic physiological structure of the baby is about positioning, and then we are ready to increase the weight quickly. Reproductive organs have also begun! At this time, the baby is no longer just an embryo, and it can be called a fetus.

The length of the fetus: about 2 cm.

Fetal weight: about 2 grams.

Week 10:
At this time, the baby has completed the most critical part of development, and it will start to stretch hands and feet to move and bones.

At this time, you can observe whether the child is a beautiful daughter or a handsome son!

Fetal weight: about 7 grams.

Week 12:
In the past month, the rapid development of the head has made the fetus look big and small, and the body and internal organs will develop. In just one month, the baby has increased by 5 times! From small cells to now, it can be called “fetal”, and now the baby has peeing itself.
