Most 8-month-old babies stand on their toes, mostly due to hypertonia and brain injury, and are often accompanied by scissor gait, inability to maintain a straight-waisted sitting position, poor awareness of active grasping of objects in both upper limbs, with or without mental retardation, delayed language development, etc. Most of them have abnormal high-risk factors, such as hypertension and hyperglycemia in the second trimester, prematurity and low birth weight, and a history of severe hypoglycemia and hypoxic-ischemic encephalopathy after birth. If you have any of the above manifestations and medical history, you should bring your baby to the hospital in time to give the necessary early rehabilitation treatment.
