Cerebral palsy has the symptom of unsteady head erection, but unsteady head erection is not necessarily cerebral palsy, and it is related to the age of the baby. Babies start to erect their heads after 2 months of age. If babies still cannot erect their heads after more than 3 months of age, it may be related to ischemic-hypoxic encephalopathy, delayed brain development, calcium deficiency, and so on. Clinical symptoms of cerebral palsy mainly include growth retardation, increased muscle tone, personality change, body weakness, mental retardation and less movement. If the baby has the symptom of unstable vertical head, you can check whether there is calcium deficiency such as micronutrients, usually more sunshine, appropriate calcium supplements, such as vitamin D drops, etc., and reasonable feeding. As the age of the baby grows more than 4 months still can not erect the head, it is recommended to go to the hospital to check the cranial magnetism, etc., cerebral palsy of the early treatment effect is better, diagnosed as early as possible after treatment.
