If there is no earwax in your baby’s ears, the water that comes in will usually flow out. If the water does not come out, a small amount of water can evaporate. If your baby has a lot of earwax, it will be soaked into a paste after entering the water. Parents should not pull out your baby’s ear at this time, because if you do, you will push the paste deeper into the ear. At this time, it is recommended to go to the hospital for otorhinolaryngology, head and neck surgery. The doctor will use a suction device to suck out the earwax from the baby’s ear, and pay attention to the baby’s earplugs when swimming.
