Babies who have bumped their heads need to be observed for their mental state and clinical symptoms. If necessary, you need to take your baby to the hospital. 1. Observe the baby’s mental state: if the baby’s mental state is good and there is no drowsiness, stupor or mental instability, it is generally not a big problem. 2. Observe the baby’s symptoms: After the baby bumps his head, pay attention to whether there are bruises and bleeding on the baby’s head, and if there are, take the baby to the hospital as soon as possible. Observe whether the baby has nausea, projectile vomiting and other symptoms, and if so, take the baby to the hospital as soon as possible. Parents are advised that if their child bumps his head, it is best to take the baby to the hospital as soon as possible to find out if there is any undiscovered trauma, so as not to delay the condition.
