Children often fall down when they walk, which may be due to ill-fitting shoes, or it may be a symptom of many diseases, such as delayed motor neural development, lack of nutrition, cerebellar hypoplasia and so on. 1. Ill-fitting shoes: After changing to proper shoes, children can walk normally. 2. Motor Neurodevelopmental Delay: Motor Neurodevelopmental Delay leads to hypotonia. Low muscle tone will cause the body to be weak and often fall down when walking. 3. Lack of nutrition: children lack of vitamin D and calcium, resulting in insufficient strength of the leg muscles, walking with no strength, and will often fall. 4. Inadequate cerebellar development: Inadequate cerebellar development will make the body uncoordinated and unable to maintain body balance, resulting in children walking and often falling. After replacing the shoes that fit well, if the children still fall down frequently, they should go to the hospital for treatment in time to avoid delaying their condition.
