Approximately one-half of all infants have their first ear infection before they are 6-months old. By the time they’re 2, about 90 percent of them have experienced at least one ear infection. Untreated ear infections can cause life-threatening illnesses, such as meningitis. Thus, it’s pivotal to treat the infection immediately. The best way to avoid these illnesses, however, is to avoid the ear infection altogether.
Now, researchers from The Research Institute at Nationwide Children’s Hospital found that feeding infants directly from the breast significantly reduces the risk of developing ear infections.
The researchers, led by principal investigator Sarah Keim, surveyed 491 mothers. Three out of four mothers said they would feed their baby using a combination of direct breastfeeding, breast pumped milk, and formula in the first 12 months.

The researchers found that after one month of breastfeeding, there was a four percent reduction in the risk of developing an ear infection. The odds were reduced by 17 percent if the infant was fed from the breast for the first 6 months.
There was a 14 percent increase in experiencing an ear infection for infants who were fed pumped milk for one month. Infants who were fed pumped milk for 6 months had an 115 percent increased risk of developing an ear infection.
"While it is not completely clear why ear infections may be related to bottle feeding, it could be because bottles can create a negative pressure during feeding,” Keim said. “This negative pressure is then transferred from the bottle to the middle ear of the infant during feedings, which may precipitate ear infections.”
The researchers also found that infants fed with breast milk for 6 months, by either from the breast or pumped milk, had a 25 percent reduced risk of experiencing diarrhea. Infants fed directly at the breast for 6 months had a 26 percent reduced risk.
The research was published last week in the Journal of Pediatrics.
