The reasons why children don’t cry at birth include neonatal hypoxic-ischemic encephalopathy, cerebral hemorrhage, and neonatal respiratory distress syndrome. 1. Neonatal hypoxic-ischemic encephalopathy: If a child is born prematurely or suffers from prolonged oxygen deprivation in the process of delivery, it may cause damage to brain cells and central nervous system injury, which will lead to the symptom that the child does not cry after birth. 2. Brain hemorrhage: newborns suffer from birth injuries during delivery, for example, if the mother has difficulty in giving birth and the doctor uses forceps or suction to help deliver the baby, this process may easily lead to brain hemorrhage caused by birth injuries, which may lead to the symptom of not crying after birth. 3. Neonatal Respiratory Distress Syndrome (NRDS): If the child is born prematurely or if the mother uses sedative drugs for a short time before delivery, this situation may easily lead to symptoms of respiratory distress after birth and cause the child not to cry after birth. If the child does not cry for a long time after birth, it is important to examine the child as soon as possible to see what causes it.
