Rethinking screen time for back to school

Smartphones, social media, and other forms of screen use are now part of children’s daily lives, leaving pediatricians to help families navigate questions ranging from when a child should receive a first phone to how parents should respond when screen use begins interfering with sleep, school, or relationships. Jeffrey Temple, PhD, professor, psychologist, and associate dean of clinical research at the School of Behavioral Health Sciences at the University of Texas Health in Houston, said the goal should not necessarily be to eliminate or strictly limit technology. Instead, pediatricians can encourage families to consider how children use devices, whether technology is displacing healthy activities, and how screen use fits within daily routines.

How can families reset screen routines for school?

That approach can be particularly useful as families transition back to school, when summer sleep schedules and less structured screen use may need to shift. Temple recommended beginning that transition gradually rather than suddenly imposing new restrictions. “When we often try to limit screen time and decide that screens are too much and kids are spending too much time on social media, we try to do an all-or-none thing, and that never works. It creates conflict, and it actually could backfire,” he said.

Temple recommended that families begin changing routines approximately 1 to 2 weeks before school starts. That can include gradually moving bedtimes earlier, adjusting morning wake times, and establishing regular periods for homework, outdoor activities, and recreational screen use. The approach reflects a broader strategy of integrating technology into family life rather than treating screen use as an activity that must always be restricted. Screens are used for school, communication, entertainment, and social interaction, and the purpose of that use may be as important as the amount of time spent on a device.

“We should spend less time sort of policing them and what they're doing now, and are they on screens now? And more time getting to know what they're doing on the screens,” Temple said. For pediatricians, this may mean asking more specific questions during visits. A child completing homework on a computer, communicating with friends, or participating in another activity online may have a different experience than a child spending the same amount of time scrolling through social media. Temple noted that technology can support education, communication, social connection, and a sense of belonging. Adults also spend substantial portions of their days using screens for work and communication, making total screen time alone an incomplete measure of whether technology use is healthy.

What does research show about screen use and child health?

Research findings have identified associations between heavier screen use and several health concerns. Temple said these include poorer sleep, less physical activity, anxiety, depression, and fewer face-to-face interactions. However, the available evidence does not establish that screen use directly causes these outcomes. “The science is not complete in this area,” Temple said. The relationship may also operate in both directions. A child with anxiety, depression, or sleep problems, for example, may be more likely to spend additional time on a device rather than the device necessarily producing those symptoms. “It’s probably a two-way relationship. So it’s hard to say that one thing causes the other. The science just isn’t there yet,” Temple said.

The potential concerns also vary by developmental stage. Among younger children, extensive screen use can replace conversation, imaginative play, and hands-on exploration. In adolescents, concerns may include cyberbullying, social comparisons, and pressure to remain continuously connected to peers through social media. These differences underscore the need for developmentally appropriate conversations rather than a single approach to screen use across childhood and adolescence.

When is a child ready for a smartphone?

One of the most common questions Temple receives from families is when children should receive their first smartphone. He said there is no universal age at which a child becomes ready. “This is probably one of the biggest questions, the most frequent question, I get asked from my friends and from concerned parents,” Temple said. “I will say that there’s not one magic age; it is really dependent on the child and how mature that child is, how ready they are to get a phone and use it responsibly, and the family’s needs.”

Family circumstances can influence that decision. A child who spends time home alone after school, for example, may need a phone earlier than another child. Temple said screens for children younger than 18 months should primarily be reserved for video chats with family members, and smartphone ownership is too early for preschool and elementary school ages. By middle school, families may begin evaluating whether an individual child is ready. Families also do not have to move immediately from no phone to unrestricted smartphone access. Temple suggested gradually introducing technology by starting with a basic phone, limiting use to calling and texting, or using controls that restrict access to certain websites or features. Restrictions can then be adjusted as children demonstrate greater maturity and responsibility.

What are the warning signs of problematic screen use?

Instead of using a specific number of hours to identify problematic technology use, Temple recommended looking at what screen use is replacing. Potential warning signs include changes in behavior and decreased participation in activities important to health and development. A child may stop spending time with friends, exercise less, lose sleep, neglect homework, or develop poorer eating habits as technology becomes increasingly central to daily life. “When you start to see your kid change personality, where they start doing those things that are unhealthy for them and focus solely on that unhealthy behavior––in this case, screen time use––well, then that is a major red flag that something needs to be [addressed], just as it would be with substance use,” Temple said.

Smartphones differ from substances, however, because eliminating them entirely may not be practical. Technology is embedded in education, social interaction, and daily communication. Temple therefore recommended making gradual changes and introducing clear boundaries rather than abruptly removing access. “I really don’t care about how much time a kid spends on the screen, as long as they’re still doing those things we know are healthy: exercising, hanging out with friends in person, you know, sleeping, those sorts of things,” Temple said.

How can parents establish healthier technology habits?

Temple recommended several household routines that pediatricians can discuss with families, including keeping devices out of bedrooms at night, making meals phone free, and maintaining opportunities for sports, hobbies, exercise, and outdoor activities. Parents’ own behavior is also part of the equation. Rules that prohibit children from using phones during dinner, for example, may be more difficult to enforce when adults continue to check email or use their own devices at the table. “When we tell our kids what to do but…we’re still using smartphones or checking emails at dinner…they still learn from us more than anything,” Temple said. “So we have to make sure that we model appropriate behavior.”

Pediatricians can also encourage parents to talk with children about their online activities. Educational use, social interaction with friends, and recreational scrolling are not equivalent simply because each involves a screen. Understanding what a child is doing online may help parents identify both beneficial activities and potential concerns. Temple pointed to the COVID-19 pandemic as an example of technology’s potential benefits. During periods of physical isolation, smartphones allowed children and adolescents to maintain friendships and communicate with others.

“Technology is not the enemy. It can help kids learn, stay connected, and even find support. The goal really is using technology, social media, smartphones intentionally, rather than letting it use us,” Temple said.

What can pediatricians discuss with families?

For pediatricians, counseling about technology can extend beyond asking families how many hours children spend on screens. Questions about sleep, physical activity, school performance, family interactions, friendships, and the purpose of online activities may provide additional information about whether technology use is affecting a child’s daily functioning. During back-to-school visits, pediatricians can also encourage families to reestablish predictable sleep and wake schedules and set consistent expectations for homework, recreation, and technology use. Gradual adjustments may make the transition easier and reduce conflict compared with suddenly imposing strict limits when school begins.

The same approach can extend beyond the beginning of the school year. Rather than viewing smartphones as inherently harmful, pediatricians can help parents identify when technology begins replacing activities that support health and development. For children approaching smartphone ownership, conversations can focus on maturity, responsibility, and family needs rather than reaching a specific birthday. For children who already have devices, counseling can focus on maintaining healthy sleep, physical activity, academic responsibilities, in-person relationships, and other activities alongside their digital lives. Taken together, Temple’s recommendations emphasize intentional use of technology rather than a universal screen-time threshold. Assessing what children are doing online, what screen use may be replacing, and how families structure technology within everyday routines can provide pediatricians with a broader framework for counseling families about digital habits.
