Infants’ head tilting back may be physiological or pathological. 1. Physiological: Infant’s head tilting backward is sometimes a normal physiological phenomenon, mainly because the infant’s neck is relatively soft, the body development is still imperfect, especially the spine, the cervical curvature has not been formed, and the weight of the head is relatively heavy, so the infant’s head is always tilted backward. Parents must be careful when holding the infant and hold the part of the infant’s head. 2. Pathological: If the infant’s head is still tilted back after a certain age, parents need to pay attention to the possibility of cerebral palsy, and parents should take the child to the hospital for a detailed examination and symptomatic treatment. There may be other reasons for infants’ head tilting backward, so it is recommended to go to the hospital in time for a complete examination to clarify the cause of the disease, and then give targeted treatment or therapy.
