A two-month-old baby who keeps tilting his head back may be an early manifestation of brain injury. In addition to tilting the body back, it is often accompanied by difficulty in breastfeeding, weak sucking, abnormal crying, good body jerking or corkscrewing, clenched fists, retraction of the shoulders of both upper limbs, hands not easily centered, body too hard or too soft, eyes not able to follow a walking person, and no obvious response when teased. In combination with the presence of high-risk factors before, at or after birth, such as prematurity, low birth weight, hypoxic-ischemic encephalopathy, hypoglycemia, etc., if you have the above manifestations and medical history, you should promptly visit the pediatric rehabilitation department for consultation and treatment, and give the necessary early intervention and rehabilitation treatment; the younger the age, the better the rehabilitation effect.
