It may be normal for babies to run diagonally, or it may be due to calcium deficiency, cerebral palsy and other reasons. 1. Normal: It may be that the baby is young, the cerebellum is not well developed, and the balance ability is still weak, so the baby always tilts his body when running. As the body develops and grows older, this condition will improve and no special treatment is needed. 2. Calcium deficiency: When the body is in a state of calcium deficiency, it may cause abnormal bone development, muscle spasms and other symptoms, so the baby’s tilted body running may be caused by calcium deficiency. You can let your baby take calcium gluconate tablets and other drugs under the guidance of the doctor to treat it. Normally, you can eat more calcium-rich foods, such as milk. 3. Cerebral palsy: Cerebral palsy is a persistent syndrome of central motor and postural developmental disorders and activity limitations, so babies running diagonally may be due to cerebral palsy. It can be treated with posterior spinal nerve rhizotomy after evaluation by a specialist and medications such as baclofen tablets under medical supervision. There may also be other reasons for the baby running diagonally. It is recommended that the baby be seen by a doctor in a timely manner for a complete examination to determine the cause of the condition and then be given targeted treatment or therapy. All of the above medications should be used under the guidance of a doctor, avoid self-medication.
