If a one-year-old baby has yellow water from the ears, there are three main situations to consider: the first one is that the child itself may have oily ears, because it is relatively small and the child is not allowed to touch the ears or clean them, sometimes these oily ear cicadas accumulate more and more, and over time they may overflow from the heavy ear canal, so there will be yellow water. The itchy feeling inside the ear canal will be more obvious, especially after water has entered the ear canal; the third case is considered to be acute purulent otitis media, most likely the child has a history of cold before, and in addition to the symptoms of yellow water in the ear, the child will also have pain in the ear canal and fever related symptoms.
