Hug reflection disappears

Infants under 3-4 months, when the mother or family suddenly walks to the child or makes a noise, they will find that the child's arms are abducted and straightened, and then they will receive the chest in the flexion, and they will hug. Cramps occur. In fact, this is not a cramp, but a physiological phenomenon, medically known as hug reflex. If there is no such reflex in the neonatal period, it means that the child is either the cerebral nervous system is not mature, and the second may be damage or disease of the nervous system, intracranial hemorrhage or other intracranial diseases.
