What does an 8-month-old fetus look like? How many pounds does an 8-month-old fetus weigh?

We all know that after a woman becomes pregnant, the fetus will continue to grow and develop in the mother's belly. The development will be different at different times. Generally, as the months go by, the fetus will gradually grow larger and its weight will slowly increase. So what does the fetus look like at 8 months of pregnancy? Let's take a closer look!

8-month fetal development

An 8-month-old fetus has the following 8 characteristics:

1. Still small

The weight of the fetus increases rapidly in the late pregnancy. Generally speaking, the weight of the fetus increases by about 200 grams per week in the late pregnancy. At this time, the weight gain is the fastest.

The fetus usually weighs less than 3 kilograms at the beginning of the 8th month, and generally weighs 4 kilograms at 32 weeks.

2. Short height

Generally speaking, the length of an 8-month-old fetus is about 36-40 cm. In the later stages of pregnancy, the length of the fetus increases at a rate of one centimeter per week.

3. Fetal position

You can turn over and over in the uterus, with the head mainly on top, and then slowly the head will turn to the bottom, because this is the normal position for the head to be down.

Generally, at 32 weeks, the doctor will tell the mother the baby's position through B-ultrasound. Generally speaking, at 32 weeks, some more B-ultrasound examinations will be performed, mainly to see whether the fetus's growth and development is too fast or too slow, whether the fetal position has become a head position, and the condition of the amniotic fluid.

4. Fetal eyes

At this time, the fetus's eyes are fully open. In the B-ultrasound, you can see that the fetus's eyelids are swollen, but they can close and open.

5. Fetal movement

Don't think that you can't move when your head is down. For the fetus, standing upside down is no problem. The fetal movement is the most during this time, because the fetal movement is not the fetus's movement, but the mother's feeling after the fetal movement. So when the fetus is 8 months old, the strength of the fetal movement is much stronger, so the mother will feel that the fetal movement is more frequent and the fetus will be more active.

6. The distinction between a boy and a girl is very clear

Whether it is a boy or a girl can be seen very clearly under B-ultrasound, which means that the child has become a little prince or princess, but the parents don’t know it yet because the B-ultrasound doctor will not tell the parents.

7. Lungs are more mature

The main reason why babies born after 8 months have a high survival rate is that their lungs are mature, so they can breathe better on their own.

People can survive for a few days without food, but they can't survive for a few minutes without breathing. Therefore, the lungs of the fetus must be mature after birth to have the ability to survive.

8. Digestive system maturation

A child's digestive system becomes relatively mature after 8 months. Some children are born at 32 weeks and can be breastfed after birth because their digestive tract is relatively mature.

8-month-old fetus development

The eighth month of pregnancy mainly refers to the 29th to 32nd week of pregnancy. At this time, the fetus is about 36-40 cm long and weighs about 1.3-2 kg. The specific data are as follows:

29 weeks of pregnancy

The fetus was about 36 cm long and weighed about 1300 g. The average biparietal diameter was 7.5±0.65 cm, the average abdominal circumference was 23.7±11.5 cm, and the average femur length was 5.61±0.44 cm.

30 weeks of pregnancy

The fetuses were approximately 37 cm long and weighed approximately 1500 g. The average biparietal diameter was 7.83±0.62 cm, the average abdominal circumference was 24.88±2.03 cm, and the average femur length was 5.77±0.47 cm.

31 weeks of pregnancy

The fetus was about 38.5 cm long and weighed about 1600 g. The average biparietal diameter was 8.06±0.60 cm, the average abdominal circumference was 25.78±2.32 cm, and the femur length was 6.63±0.38 cm.

32 weeks of pregnancy

The fetus was about 40 cm long and weighed about 1800 g. The average biparietal diameter was 8.17±0.65 cm, the average abdominal circumference was 26.20±2.33 cm, and the femur length was 6.43±0.49 cm.

From the data, we can see that the weight of the fetus increases very quickly, about 200-300 grams per week. The fetus slowly develops from a wrinkled old man into a chubby little fetus, becoming more and more cute!

In addition to increasing length and weight, the various organs of the fetus are also working hard to develop and mature. For example, the fetal bone marrow can produce blood on its own, but it still needs the help of the pregnant woman. The fetal muscles are becoming stronger and stronger, and the nervous system is also particularly well developed. The fetus can control its own flexible movements. However, there are also areas of underdevelopment. For example, the fetal lungs have not yet fully developed and cannot adapt to the environment outside the uterus for the time being. They need to continue to develop and mature in the pregnant woman's belly.

Due to the rapid development of the fetus and the filling of intrauterine space and amniotic fluid, the fetal movements are becoming more and more intense, and pregnant women often have stomach pain due to kicking. However, when the pregnancy is about 36 weeks, the space will become narrower, and the fetal position is basically fixed, the frequency and amplitude of fetal movements will be reduced. Pregnant women should not worry too much and pay attention to the fetal movements. Only if they are regular and rhythmic, the fetus will develop very healthily.

What should you pay attention to when you are 8 months pregnant?

Security Question

Be careful when walking around the house or going out shopping or taking a stroll. Pay attention to the potholes on the road and don't fall. Be careful not to let others bump into you. Stay away from pets such as cats and dogs or stray animals.

Dietary issues

You should control your food intake appropriately and not eat too much. This stage is when the fetus grows the fastest. Eating too much will make the pregnant mother obese and the fetus grow too big, which is not conducive to delivery. I became fat because I ate too much. Later, the prenatal doctor told me seriously that I should eat less.

Exercise Problems

Walking is the best exercise at this stage, and you can take a 30-minute walk one hour after a meal. Because I had signs of threatened miscarriage in the early stages of my pregnancy, my family and I were very careful throughout the pregnancy. I basically rested at home and did less exercise, which may have been a factor in my failure to give birth naturally later.

Prenatal check-up questions

Prenatal checkups become more and more frequent as you get into the later stages of pregnancy, which is normal. B-ultrasound, measuring uterine circumference, listening to fetal heart rate, and counting fetal movements may cause the fetus to be in a bad position or the fetal heart rate to be substandard. Don't worry too much, just follow the doctor's advice. When I was about to give birth, I found that the baby was in a transverse position. I was so anxious at the time that the doctor asked me to come back and do some exercises, and the fetal position was corrected by the due date.

Mood problems

It is very important to have a good mood during pregnancy. There are many discomforts during pregnancy, which can sometimes make people crazy and irritable. Controlling your emotions and maintaining a good mood are also beneficial to the fetus in the belly. The fetus can feel the mother's joys, sorrows, anger and happiness, and a good mood helps the child to be cheerful and lively.
