is common in children, you need not worry about this. It cannot invade into the brain so easily. Ear infection can be secondary to eustachian tube (the tube connecting the nose and the ear) block. Adenoids
or nasal allergy
can be the main culprit. If the child is having any cold
associated with this, please use saline nasal drops, give warm water for drinking. If there is any discharge from the ear avoid water into the ears. Any more doubts you are welcome.
