A study from the University of California found that allowing kids to have screens in their bedrooms is associated with 44% higher odds of kids consuming mature content. Researchers analyzed 10,054 kids aged 12 and 13 and found using screens at mealtime was also a risk factor for consuming R-rated movies and mature video games. What can parents do? Being an example of good behavior and screen time limits tend to be more effective than punishment. “Children often model their screen habits after their parents, so setting a positive example can make a big difference,” Dr. Jason M. Nagata said.
