Can spending too much time with a smartphone or tablet negatively affect child development? That depends on the expert you ask.\n\n\nUntil recently, the influential American Academy of Pediatrics\u00a0(AAP) took a strong negative stance on screen time for kids. However, the group has softened its position. In\u00a0a research paper\u00a0the academy released earlier this month, it wrote,\u00a0"[d]igital media can be used to facilitate executive function (reasoning and problem solving), build self-control and problem-solving skills, and improve children's ability to follow directions."\n\nA change of tune on children and digital displays\n\nThe paper does not exactly deliver a ringing endorsement of digital gadgets for kids, but it represents a significant change from another previous, well-publicized publication from AAP. In its 2013 paper, the academy said "the evidence is now clear that they (media) can and do contribute substantially to many different risks and health problems and that children and teenagers learn from, and may be negatively influenced by the media." It then advised parents to:\n\n\nLimit the amount of total entertainment screen time to less than two hours per day\nDiscourage screen media exposure for children younger than two years old\nKeep the TV set and Internet-connected electronic devices out of children's bedrooms\n\n\nSo why the change of heart? In the two years following that 2013 paper, smartphones and tablets became nearly ubiquitous. In May, the academy convened a symposium of "leading social science, neuroscience, and media researchers, educators, pediatricians, thought leaders, and representatives from key partner organizations" to reexamine the issue.\n\n\nAmong the other recent findings, the panel says "[p]arents should let their children teach them about media and participate with them. Media should be viewed as a tool rather than a babysitter, reward, or punishment."\n\nLasting effects of smartphones, tablets on kids still unclear\n\nOther experts maintain that digital screen time may still be problematic for young children. In a paper published in September by the Brookings Institute, a group of researchers argued that simple, traditional toys, such as building blocks, are much better for development than electronic devices. They also found that "when parents read ebooks rather than traditional books to their three-year-olds, their children are less likely to follow the plotline."\n\n\nThe researchers conceded that more study is needed, and they concluded their paper with this bit of basic advice: "Play that is 90 percent toy and 10 percent parent-child is not as educational as play that is 90 percent parent-child and 10 percent toy."
