How is the baby's physical development during the 30th week of pregnancy?

After becoming pregnant, every mother may think about who the baby will look like after birth, what the baby looks like in the belly now, whether the baby is a boy or a girl, etc. Thirty weeks of pregnancy is already the late stage of pregnancy, so the mother's body will become heavier and her movements will be relatively slower. In addition, at this stage, many pregnant mothers begin to gain weight, and some may even experience swollen legs and feet. But no matter what, what the mother is most concerned about is the baby's condition. Let's take a look at the baby's development during this period!

At 30 weeks of pregnancy, the fetus is about 28 cm tall when sitting, about 44 cm long from head to toe, and weighs 1400-1500 grams. At this time, the standard biparietal diameter of the fetus is 7.83 ± 0.62 cm, and the femoral length is 5.77 ± 0.47 cm.

The baby can distinguish light. The fetus' eyes can open and close freely and can see the scenes in the house. He can also identify and track light sources... Physiological changes in expectant mothers: At 30 weeks, the uterus has risen to the diaphragm, so pregnant women will feel difficulty breathing, shortness of breath, stomach discomfort after eating, etc. These are all normal and there is no need to worry. In addition, as the fetal head begins to descend and enter the pelvis, the discomfort will gradually ease. The first thing to pay attention to this week is "fetal position". In the late pregnancy, the normal posture of the baby in the uterus should be head down and buttocks up, so that the head can be delivered first during delivery. Whether the fetal position is normal or not is very important, as it affects whether the delivery can proceed smoothly. Before 28 weeks of pregnancy, the baby is still small and the amniotic fluid is relatively abundant. Even if the fetal position is malpositioned, it can usually be corrected on its own. However, if the fetal position is still malpositioned after 30 weeks of pregnancy, self-correction should be performed under the guidance of a doctor.

The amount of leucorrhea will increase in the late pregnancy. Improper care may cause vulvitis and vaginitis, resulting in the fetus being infected when passing through the vagina during birth. Therefore, we should pay attention to keeping the vulva clean and hygienic in daily life. If the vulva becomes itchy, the amount of vaginal discharge increases, the color and properties change, and there is a bad smell, do not use highly alkaline soaps to clean the vulva. See a doctor immediately and follow the doctor's instructions for care. Fetal development status: The 30-week fetus is now about 44 cm tall and weighs about 1500 grams. The fetus' head continues to grow and its brain develops rapidly. The brain and nervous system have developed to a certain extent, and subcutaneous fat continues to grow. This week, the fetus' eyes can open and close freely, and can probably see the scenes in the womb. The child can also recognize and track light sources. But you can't expect a baby to have sharp eyes from the beginning. Usually, a baby can only see things at a very close distance when it is born, and can only see distant objects and people gradually. The fetus is surrounded by amniotic fluid in the uterus. As the fetus grows, fetal movements gradually decrease.

In the late pregnancy, around 30 weeks, the mother and baby should pay attention to taking in a full range of nutrients to ensure the good development of the baby's body. In addition, mothers should also pay attention to walking outdoors more often, especially in the morning and evening to bask in the sun. Breathing more fresh air is also beneficial to the baby's growth and development. Also, you need to relax and keep a happy mood. Don't put too much pressure on yourself, but don't be too nervous.
