Speaking of babies, everyone must know that it refers to newborn babies, which I believe everyone will experience, because we have also grown from babies.
Did you know?
Crying at birth is a normal reaction, and the level of a baby's crying can prove the size of the baby's lung capacity.
Because the baby does not need oxygen when it is in the mother's body, it is surrounded by amniotic fluid, the lungs are filled with fluid, in an occluded state, and cannot breathe. At the same time, the baby is in the mother's body for up to ten months, all of which are obtained through the umbilical cord nutrition and oxygen.
During the birth process, the baby has to leave the mother's body and enter the external environment, and in an aerobic state, the alveoli must open so that gas enters the lungs for gas exchange. Therefore, after the baby is born, the baby needs to convert this process by breathing himself to absorb oxygen.
If the baby does not cry at birth, it may cause the lungs to not open in time, or because the amniotic fluid is inhaled into the alveoli, resulting in the baby being unable to breathe normally, dyspnea, hypoxia and other manifestations, and in severe cases, it may also affect intellectual development, and there will be neonatal hypoxia asphyxia, and even life-threatening.
So when a baby is born without crying, the doctor will play the baby's foot or pat the baby's butt until the baby cries. The newborn baby is beaten because he does not cry, and the mother must not be distressed to make trouble with the doctor!
And when the baby cries, it can also promote the development of the baby's mouth muscles, expand lung capacity, let the baby adapt to the external environment faster, on the other hand, you can also roughly test the baby's health!
