New York Daily News:
Not being able to talk doesn’t keep babies from enjoying a good laugh and even forming friendships with others, according to researchers from Australia who’ve spent the last two years studying child behavior.
Academics at Charles Sturt University are studying how children interact with other infants while in childcare using footage obtained from tiny cameras strapped to their heads.
The study affords a "baby's eye view" of the world in which even simple objects such as spoons appear oversized, said Jennifer Sumsion, foundation professor of early childhood at the university.
But it also shows that children aged from six months to 18 months use sophisticated but subtle non-verbal means to make friends and make each other laugh.
