It is normal for 80-day-old babies to be unable to raise their heads; however, it is abnormal if it is caused by cerebral palsy, strabismus and other pathological factors. 1. Physiological factors: 80-day-old babies can’t raise their heads, mostly due to physiological factors, such as the lack of targeted exercise, as well as individual differences, will affect the baby to raise his head, and need to strengthen the exercise can be. 2. Cerebral palsy: If the 80-day-old baby has a history of hypoxia and ischemia or intrauterine asphyxia, it is easy to lead to cerebral palsy, which is manifested in the inability to raise the head, and other large motor and fine motor development will also appear behind the phenomenon. 3. Strabismus: 80-day-old babies with strabismus are also prone to difficulty in lifting their heads, which is often manifested by head tilted to one side, and a mass can be seen at the sternocleidomastoid muscle. If necessary, ultrasound can be perfected to assist in the diagnosis. If your 80-day-old baby can’t hold his head up, we recommend regular visits to the Child Health Unit for targeted treatment under the guidance of your doctor.
