Frequent jumping in babies may not necessarily be brain damage, but may be related to calcium deficiency, but also need to be examined to rule out whether there is brain damage or other causes. Babies’ nervous system is not yet very mature, and they are easy to be frightened. If they frequently jump, you can go to the hospital to check whether they are calcium-deficient, as calcium-deficient babies are prone to generalized trembling. Brain injury is usually in addition to jumping, will be accompanied by other abnormalities, such as breastfeeding difficulties, crying too much or too little, easy to tilt the head back, toe to the ground, mental retardation and other symptoms. It is recommended that babies with frequent jumping should be taken to the hospital in time for relevant examinations to identify the cause and then targeted treatment.
