'Parents need to act as media mentors and consider how much their child's use, let alone their own use, displaces face-to-face interactions,' an expert told Newsweek.
Kindergartners who use screens for more than two hours a day are more likely to show signs of behavioral problems, such as attention deficit hyperactivity disorder , according to a study by Canadian scientists.
The study had their parents complete a frequently used questionnaire designed to pick up mental health and behavioral issues at age 3, and again at age 5. The parents were asked how much their children used screens, and how much they engaged in physical activity. They were also asked for other information, such as their socioeconomic status.
Using this data, the researchers placed the children into four categories, acording to the Canadian government's guideline that children between the ages of 5 and 13 should spend no more than two hours using screens, or one hour for 2- to 4-year-olds.

Past studies have linked screen time to poor eating habits, low-quality sleep, heart disease and obesity in children, the authors noted. Evidence suggests that using such devices could cut into the time children need for mental development. One study published earlier this year on Canadian children found that children who used screens for more than one hour a day at 24 months had a higher risk of developmental problems at 36 months, and 60 months.
But she pointed out two limitations: First, the study considered only the amount of screen time, not the types of content or whether the children were supervised by parents or joined by friends when they used their screens. Second, parents’ subjective perceptions were used as a measure of a child’s progress, which could skew the results.
