Can children swim if they have ear tubes?

If your child has ear tubes — tiny cylinders placed through the eardrum to drain fluid and allow air into the middle ear — ask his or her doctor about ear protection during swimming. Some doctors recommend that children who have ear tubes wear earplugs while swimming to prevent bacteria from entering the middle ear. However, routine use of earplugs might only be needed when children dive or swim in untreated water, such as lakes and rivers.
