Six year old babies generally need to be observed for about 72 hours after a fall. Baby falls, especially head trauma, require extra vigilance and attention. If the fall injury of a six-year-old baby is serious, symptoms may appear immediately after the fall, such as headache, vomiting, unconsciousness, and progressive enlargement of local hematoma. If the baby does not have symptoms and clinical manifestations immediately after the fall, it can be observed clinically for about 72 hours after the fall, and if the above symptoms appear, it is necessary to go to the hospital immediately for appropriate examination. If the baby fell part is the head, the fall injury can cause serious skull fracture, brain hemorrhage and even endanger the baby’s life, so do not paralyze the baby after the fall.
