50 yrs ago, kids spoke in full sentences btn 2-2.5 yrs old. Kids today speak in full sentences btn 2.5-3. That’s a 6-month delay. Why? Kids in front of TV/computer spend less time absorbing language. Studies show kids of deaf parents who are put in front of TV to “learn” language can mimic words, but they do not understand that spoken language is used for communication. TV doesn’t teach. Human interaction does.
