There are several studies keep on publishing in the literature about infants' watching television.
They are showing a strong evidence in negative effects on infants' language acquisition skills, development of their IQs and even they are becoming more aggressive individuals.
Parents should be encourage to provide speech input to their children by talking them, not by watching TV together with them.
Turn off your televisions, if you have kids at home and especially if they are younger than 2 years old.
