It turns out, a lot gets lost in translation when you talk to a baby in baby talk. A new study from the University of Washington found that babies who are spoken "parentese" have better language development than babies who are spoken to in "baby talk." The study was published in the Proceedings of the National Academy of Sciences.
Baby talk tends to consist of simplified grammar and exaggerated sounds. "What people think of as baby talk is a combination of silly sounds and words, sometimes with incorrect grammar," Naja Ferjan Ramirez an assistant professor at the department of linguistics at the University of Washington told CNN, "like 'Oooh, your shozie wozies on your widdle feets."
