Question

15．Parents should ban electronic media during mealtimes and after bedtime as part of a comprehensive"family media use plan"，according to new recommendations from the American Academy of Pediatrics．"Excessive media use is associated with obesity，poor school performance，aggression and lack of sleep，"said Marjorie Hogan，co-author of the new policy．
Families should have a no-device rule during meals and after bedtime，the guidelines say．Parents should also set family rules covering the use of the Internet and cellphones，including，perhaps，which sites can be visited，and who can be called．The policy also restated（重申）the existing recommendations：Kids should limit the amount of screen time for entertainment to less than two hours per day；children younger than 2 shouldn't have any TV or Internet exposure．Also，televisions and Internet-accessible devices should be kept out of Kids'bedrooms．
Doctors say parents need to obey the family rules，too，to model healthy behavior．That，some say，may be the toughest part．"If you go to any restaurant，Family 3.0 is Mom and Dad on their devices and the kids on theirs，"says Donald，a pediatrician（儿科医生）and an APP spokesman．"Who is talking to each other？"
Children aged from 8-18 spent an average of 7 hours and 38 minutes a day consuming media for fun，including TV，music，video games and other content in 2015，according to a 2016 report from the Kaiser Family Foundation．The report was based on a survey of 2012 third through twelfth graders，702 of whom completed a seven-day media use diary．That was up about an hour and 17 minutes a day from five years earlier．About two-thirds of 8 to 18-year-olds said they had no rules on the amount of time they spent watching TV，playing video games or using the computer，the Kaiser report found．
Use of mobile devices by young kids has soared（飙升）．A new report from Common Sense Media，a child-advocacy group based in San Francisco，found that 17% of children aged 8 and younger use mobile devices daily，up from 8% in 2011．
