We either don't have an ideal treatment or we lack data about which current treatment is better. I cannot prescribe treatment in a column, but I can give some general advice. In the case of recurrent or chronic otitis, find a pediatrician you trust whose decisions make sense. Get a second opinion from another pediatrician if you feel it is necessary. Ask for a hearing test to be done if you have any suspicion about diminished hearing.
Children do grow out of the otitis years.
Usually by school age, earaches are much less common. While waiting for the child to grow out of it, parents and pediatricians have to work together to prevent hearing loss. The parents' job is to report any ear or hearing symptoms and do the best they can to prevent colds. We know that hand washing is the best way to keep colds from spreading, so have plenty of soap and use it. All immunizations should be up to date.
