Fetal size at 20 weeks of pregnancy

The growth of the fetus in the womb also has a specific process. From head to toe, the changes in various bones and body weight are very fast. Mothers are also very concerned about how big the fetus is in the womb. This is especially obvious for babies in the 20th week of pregnancy. This period is particularly important. The baby will begin to develop rapidly from this stage. So how big is the baby at this time? Let’s take a look together.

At 20 weeks of pregnancy, the fetus is about 25 cm long from head to toe and weighs about 320 g. The average biparietal diameter is 4.88 ± 0.58 cm, the average abdominal circumference is 14.80 ± 1.89 cm, and the femur length is 3.35 ± 0.47 cm.

At 20 weeks of pregnancy, the baby's senses begin to develop rapidly, and taste, smell, hearing, vision and touch all enter a critical development period. In order to protect the skin, lipids begin to form and slender eyebrows grow. His eyes could move now, although ultrasound showed that he could only keep his eyes closed.

At 20 weeks of pregnancy, the fetus's limbs are now well developed and its hair is growing rapidly. He started swallowing the amniotic fluid and could already pee! His movements will start to become very frequent, and he will often roll over, causing his mother to be unable to sleep at night.

It can be seen that the baby at 20 weeks of pregnancy has entered a critical period. After that, you should pay more attention to the child's dynamics, measure the uterine height in time, and go to the hospital for routine examinations in time. At the same time, you should continue to pay close attention to prevent any unnecessary mistakes, create a good environment for the child, and let the child be born smoothly.
