So Cute: Babies Love to Hear Each Other Babble

Baby babble
Sure, your baby loves to hear your high-pitched coos and murmurs—and engaging in such baby talk with your wee one is actually good for her.

But new research from McGill University found that your infant is more likely to be interested in the sound of another baby — even before she's able to babble herself.

To determine which sound held infants' attention longer, researchers had 6-month-olds listen to vowel sounds from an adult woman and a baby (watch the adorable video!). While the babies' faces were often neutral when they heard the adult, they often responded by smiling when they heard another baby's sounds.

The study, which was published in Developmental Science, concluded that infants listened to the vowels made by other infants about 40 percent longer than the sounds made by an adult.

"This is not a preference for a familiar sound because the babies who took part in the experiment were not yet babbling themselves," the press release stated. "So the infant-like vowel sounds that they heard were not yet part of their everyday listening experience."

Researchers believe this could lead to further investigation into the processes that are involved in baby's language development, which could potentially alleviate problems (like hearing impairment) that interfere with development.
