Article | Mother Mo’s Parenting Manual

During pregnancy, I believe mothers have fantasized about the appearance of the baby in their belly more than once!

At 20 weeks of pregnancy, mothers have been pregnant for 5 months. The 10-month pregnancy has also passed half the mileage. Although it is still a long time before the baby appears, this time At this time, mothers can already "really" feel the existence of a little life in their belly, so what does the fetus look like at this time?

1. The length and weight of the baby at 20 weeks of pregnancy:

The baby at 20 weeks of pregnancy is already like a Melon is so big. The baby's body length is about 25cm, head-to-rump length is about 16cm, and weight is about 320g. The growth tends to be stable.

2. What the baby looks like at 20 weeks of pregnancy:

At 20 weeks of pregnancy, the baby’s arms and legs are in proportion to the rest of the body, and the hair on the scalp begins to grow. Eyebrows have also begun to form, the skin is dark red, and the body is covered with vellus hair. The surface of the baby's body will also be covered with a layer of white fat, which is what we call vernix.

3. The baby’s skills at 20 weeks of pregnancy:

At 20 weeks of pregnancy, the baby has also learned a lot of skills. The baby’s muscles have developed faster and his physical strength has also increased. Many of the little hands and feet can move freely in the amniotic fluid. The space left for the baby in the uterus is large enough, so the baby can twist, turn over, kick, and even do somersaults occasionally in the mother's belly. Sucking fingers, burping, rubbing eyes? At this time, most mothers can already feel these movements of their babies, that is, fetal movements, but the fetal movements that mothers can feel at this time are still relatively slight.

4. Fetal development:

At 20 weeks of pregnancy, the baby’s sensory organs are developing During the peak period, taste, smell, hearing, and vision all enter a critical development period.

At the 20th week of pregnancy, which is 5 months, the fetus has begun to establish an auditory system, has also developed visual response capabilities, and taste organs have also begun to form.

At the same time, the tactile response has also been initially established. If the mother presses the baby's position with her hand when she feels the baby kicking her belly, the baby can also feel it and sometimes respond to the mother.

In addition, the baby's heart is getting stronger and stronger, and the blood in the umbilical cord flows rapidly. It only takes 30 seconds to complete the circulation between the entire umbilical cord and the baby. At this time, the kidneys also take over. In order to produce amniotic fluid, the baby swallows amniotic fluid in the mother's belly to promote its own digestion, excretion function and lung development. The swallowed amniotic fluid will enter the fetal blood circulation through the digestive tract, form urine, and finally be excreted into the amniotic fluid. middle.

The above is a series of changes in the baby at 20 weeks of pregnancy. Next, let’s talk about the changes of the mother at 20 weeks of pregnancy:

At 20 weeks of pregnancy, the fundus of the uterus has reached the navel. The mother's belly is getting bigger and bigger, her weight has increased dramatically, and she has become close to the figure of a typical pregnant woman. Most mothers have a very obvious pregnancy belly at this time, and they can no longer hide the fact of pregnancy.

At this time, some mothers will also experience itching in the abdomen, and the changes in the breasts will also be very obvious. The color of the areola and nipples will obviously deepen; some mothers will find that a black line begins to appear in the middle of the belly at this time. ?, this "black line" is what we call the pregnancy line. The pregnancy line usually starts to appear little by little after the belly gradually swells in the second trimester. Every mother's constitution is different, so the pregnancy line will also have different The difference is that some mothers have dark and thick pregnancy lines, while some mothers have very light and thin pregnancy lines. The pregnancy lines usually gradually fade after delivery, so mothers do not need to worry.

? Symptoms that mothers may experience at 20 weeks of pregnancy: False contractions: The mother’s uterus begins to have painless, irregular, and asymmetric contractions at 12-14 weeks of pregnancy. , but most mothers can only notice it clearly after 20 weeks of pregnancy. The mother feels that her belly is tight and hard, shrinking into a ball, lasting for a few seconds, and then returning to normal after more than ten seconds. This is a false contraction. Dizziness: During the entire pregnancy, the content of progesterone in the blood is very high. It causes the blood vessels to relax and thicken, increasing the blood supply to the fetus, but reducing the blood supply to the mother. Reduced blood flow means damage to the brain. The blood supply is reduced, which will cause the mother to feel top-heavy and dizzy (ps: hypoglycemia, getting up too fast causing a drop in blood pressure, the growing uterus compressing blood vessels, anemia, etc. can also cause dizziness). Abdominal pain: Most mothers will experience pulling pain on both sides of the abdomen at this time. Sometimes it is spasmodic. It is most likely to occur when the mother suddenly gets up, sneezes, or stays in one position for too long. This is the growing pain during pregnancy. Pain caused by the enlargement of the uterus and the stretching of the ligaments and muscles that support the uterus.

In addition to the above points, mothers may also experience symptoms such as leg enlargement, nosebleeds, increased appetite, strong hunger, calf cramps, and increased vaginal discharge during the 20th week of pregnancy?
