Why do newborns sleep restlessly and always make a lot of money?

Hello, the newborn's nervous system development is not perfect, and the nerve's excitation and inhibition functions are not coordinated enough, so it is easy to get excited. A little external stimulation may cause the excitement of the nervous system and surprise the baby. This is a normal physiological phenomenon. As the baby grows up, the nervous system will naturally disappear. The baby is moving all over, and sometimes his face is red. This is a normal phenomenon. Old people often say that the baby pulls out and the baby pushes hard. This is growth.
