A foul odor emanating from the ear. An ear infection results when fluid and bacteria build up in the area around your baby's eardrum. Bacteria like to grow in dark, warm, wet places, so a fluid-filled ear becomes the perfect breeding ground. As the infection worsens, so does the swelling in and around the eardrum, and, as a result, the pain. Fever develops as your baby's body attempts to fight the infection.
Ear infections are one of the most common childhood illnesses.
While there are no statistics on how many babies get them, the American Academy of Pediatrics expects that most children will have gotten at least one ear infection by the time they turn 3.
