One-and-a-half-year-old boy walks like an O-shaped leg and an inner figure. What should I do?

In fact, when babies first start walking, most of them have a gait with an inner figure of eight, but the degree of severity is different. When a baby lies down after birth, his legs are curled up, just like a frog. It is a phenomenon that the baby walks with eight characters. There are many reasons: 1. When the baby walks, in order to stand and land comfortably, he naturally corrects his body gravity and adopts different gait. This is obviously physiological. If the situation is not serious, with the baby's growth, the inner eight-character phenomenon will disappear. 2, tibial internal rotation deformity, this is a congenital phenomenon, the baby's tibia is not straight, and it turns inward at the ankle, and there is an internal figure of eight when walking. This situation must be treated in the hospital as soon as possible, and corrected by wearing special shoes with internal figures of eight, orthopedic shoes. This kind of shoes is customized according to the pronation of the baby's feet. The upper is high and can fix the baby's ankle joint. The bottom is made into a certain slope according to the cause of the baby's feet. With the change of the baby's gait, a pair of shoes is usually changed every six months. I suggest that mom put the baby's shoes on backwards first.
