If the baby’s cry is straight, with no gyrating or bending of the voice, medically known as cerebral cry, be aware of the presence of brain damage. And we should pay attention to whether there are high-risk factors before, during or after birth, such as hypoxic-ischemic encephalopathy, prematurity, low birth weight, etc. We should pay attention to observing the activities of the baby’s limbs. If the limbs are too soft or too hard, the baby’s body is too active or too inactive, and the baby has difficulty in breastfeeding, then it is necessary to go to the Department of Rehabilitation of the child in time for consultation, and if necessary, to carry out the cranial magnetic resonance imaging (NMRI) and the relevant measurements such as the Neuropsychological Development Scale (NDS). If there are abnormalities, early intervention is needed, and the younger the baby is, the earlier the intervention, the better the result.
