How big is the belly at 4 months of pregnancy

At 4 months of pregnancy, the belly is just big enough to be visible. At this time, the belly is relatively small, especially for obese pregnant women, it is difficult to see, while it is more obvious for thin pregnant women. However, we can judge the development of the fetus from the mother's weight, because many clothes for women are not suitable. It is best to choose maternity clothes. Do not wear tight clothes, which will affect the development of the fetus. Make sure the clothes are loose.

How big is the belly when you are four months pregnant

When the pregnant woman is four months pregnant, her belly is not very big, but it can be seen. During this time, the mother's weight will increase by 2 to 4.5 kg, and many clothes will no longer fit. During this period, the fetus is in a period of rapid growth, and its length may increase from 13 cm to 17 cm, which is a very fast speed. The fetus weighs about 200 grams, and the eyes that were originally tilted to the sides begin to focus forward. The fetus's bones have almost become rubber-like cartilage at this time and begin to gradually harden.

At this time, the girl's vagina, uterus, and fallopian tubes are ready, and the boy's genitals can also be seen clearly. The baby's brain is at the peak of rapid development at this time. Brain cells proliferate rapidly, and the brain begins to divide into specialized areas for the development of smell, taste, hearing, vision, and touch. The fetus's retina also begins to form. In short, the fetus at this time is basically in adult shape.

Four months of pregnancy baby's ability indicators

The fourth month of pregnancy enters the second trimester. At this time, the fetus's limbs become more and more developed. His fingers can begin to clench with his palms, his toes and soles can also bend, and his eyelids remain tightly closed. They already know how to listen to their parents. At this time, the facial muscles of the fetus begin to be exercised due to the stimulation of the brain nerves. They can frown, squint, and do other movements in the belly. Although their hands and feet are not long enough, their bodies begin to grow faster than their heads, and their necks begin to become more distinct. What’s even more amazing is that at this time the fetus’ respiratory system is gradually improving and they are actually already learning to breathe. The fetus can still hiccup at this time, but we just can't hear it. They may even make a fist, open their mouth, and suck their fingers.

In addition, although the fetus' eyelids are still closed at this time, they can already feel the light. At this time, the fetus' taste buds are gradually formed and begin to absorb nutrients from the amniotic fluid. You will find that they prefer sweets!
