You may be able to lower your child's risk of otitis media by doing the following:
Breastfeed your child because breastfeeding seems to offer some protection against otitis media.
Make sure your child gets all of his or her pneumococcal and Haemophilus vaccines.
Avoid rooms with secondhand smoke, because environmental cigarette smoke may increase a child's risk of ear infections. Secondhand smoke disrupts the function of the Eustachian tube and changes the protection mucus provides. If you smoke cigarettes, try to quit, or at least avoid smoking near children.
