Why does a newborn baby only cry and not laugh?

Newborns also laugh, but newborns' laughter occurs more often during sleep and less often when awake. Some babies have better physical development and early intellectual development, and may smile in more than two months. Children often begin to smile and have facial expressions at the first 2 months of life, but are unable to laugh.

Yes, the lack of laughter may be caused by the desire to rest, or it may be caused by personality.

Newborn babies will also laugh, babies do not like to laugh, because of the baby's personality, parents do not force, can be cultivated in the later life of the baby's personality changes.

Since they never breathed with their lungs, they were not skilled at first, and their breathing always led to a vigorous rubbing of the vocal cords, forming a cry similar to a cry. As the breathing gradually becomes proficient, the body's various functions gradually cooperate and improve, and the airflow will no longer hit the vocal cords during breathing, and it will no longer cry all the time.

It is normal for the baby to cry, indicating that it can breathe on its own, the baby is crying because the respiratory tract has been opened, the vocal tract is normal, the baby does not cry, and the doctor will pat the baby's buttocks.

It is a normal physiological process for a child to cry at birth, because the child is almost not breathing or only very weak breathing in the uterus, his lungs are full of fluid, if the child wants to breathe and live independently after birth, then the lung fluid needs to be discharged in time, and crying after birth can make the lungs expand quickly. Lung fluid is quickly absorbed through lymphatic vessels and blood vessels, and the child's ** will quickly turn red, if the newborn does not cry or the cry is very weak, the medical staff should immediately carry out rescue treatment.

Loud crying after birth causes the lungs to expand rapidly, lung fluid is rapidly absorbed through the lymphatic vessels and blood vessels in the lungs, and the child's skin color turns red rapidly. Premature infants or small infants with intrauterine hypoxia and other abnormal conditions often do not cry or cry weakly after birth, and medical personnel should be rescued immediately.

Because at that time, the baby's lungs have not yet opened, and the baby can only promote the development of the lungs and the expansion of the lungs after crying, which is very advantageous. If your baby doesn't cry, worry about whether your baby has inhaled amniotic fluid and caused the suffocation.

If the baby doesn't make a sound, he will hit him, so he will cry, if he doesn't hit him, his lung capacity can't breathe air, it's easy to suffocate.

Crying when a child is born is a normal physiological process. The child is almost non-breathing or only very weak in the womb, the lungs are full of fluid, and the child needs to breathe and live independently after birth, and the lung fluid needs to be discharged. Crying loudly after birth can cause the lungs to expand quickly, and the lung fluid is quickly absorbed through the lymphatic vessels and blood vessels of the lungs, and the child's complexion will quickly turn red.

Premature infants with intrauterine hypoxia or relatively small babies and children with other abnormalities often do not cry or cry weakly after birth, and medical staff should immediately carry out rescue treatment.
