If the baby is not unconscious or vomiting, just crying for a short time, playing and eating are normal, there may not be much problem in the cranium, just pay attention to the observation. If the baby vomits more frequently after the injury, does not wake up from sleep, or vomits frequently after feeding and watering, we should pay attention to the existence of intracranial injury, and go to the hospital in time to carry out a cranial CT examination to exclude the existence of combined cerebral contusions, so the baby should pay special attention to observation after the fall of the hindbrain, especially at night, even after going to sleep, every 1-2 hours must wake the baby up If there is no abnormality, continue to observe the baby’s activity, and if there is drowsiness or urinary or fecal incontinence, go to the hospital in time to prevent accidents.
