The Impact of Screen Time During the First 1,001 Days: A Global Study Sounds the Alarm

Scientists Sound the Alarm on Early Exposure to Digital Devices

From the moment they are born, children today grow up in an environment saturated with screens. Phones, tablets, laptops, and televisions have become indispensable parts of everyday family life. According to a recent global report, this ubiquity makes it nearly impossible to protect babies from regular exposure to digital devices.

A comprehensive systematic review—described as the most exhaustive to date on the subject—examined peer-reviewed research from around the world. Conducted by the iADDICT research group, the study highlights that regular and intentional screen time during the first 1,001 days of life—a period spanning from pregnancy through a child’s second birthday—may be linked to long-term concerns regarding health, development, and overall quality of life.

In fact, scientists found little evidence suggesting that these devices offer significant developmental benefits for children under the age of two. Based on this finding, members of the iADDICT group recommend that no regular or intentional screen time be allowed before the age of two. They also urge policymakers to review guidelines encouraging shared screen time with infants, as well as marketing strategies that label these technologies as suitable for “all ages.”

Key Issues in Cognitive and Emotional Development

Child development experts agree that the first 1,001 days are one of the most critical phases of human life. During this period, the brain undergoes rapid growth. Infants lay the groundwork for learning, movement, emotional regulation, social skills, and language, primarily through direct interactions with their caregivers and their physical environment.

The analysis highlights that screen use during this critical window can significantly reduce infants’ opportunities to bond with their caregivers, play with other children, or develop their language skills. At the same time, this exposure has been linked to an increased risk of overstimulation, sleep disturbances, eye health problems, childhood obesity, and a reliance on digital devices to regulate emotions.

However, the study’s authors take a nuanced stance, noting that this review did not establish direct cause-and-effect relationships between screen use and specific developmental disorders. The findings suggest strong correlations that warrant increased vigilance, without, however, establishing absolute clinical certainties.

The Lack of Guidelines and the Impact of Adult Habits

To better understand families’ experiences and concerns, this research project included an online survey combined with focus group interviews involving 174 parents in the United Kingdom. The findings reveal that many parents receive very little guidance from healthcare professionals regarding screen use during early childhood.

"We have learned that screen use among children under two is a global concern that, as of 2026, is not being adequately addressed," said Rafe Clayton, associate professor of media and communication at the University of Leeds and co-author of the study. “This has implications for an entire generation and its future quality of life. Screen time guidelines exist for children but are not being followed, in part because the adults who set the precedents for societal use lack guidelines themselves.”

With the ongoing digital revolution, problematic screen use has become commonplace among adults. Despite strong public support for official recommendations, the British government has not issued any guidelines on this subject for adults. In the absence of guidelines, adults may unintentionally pass on unhealthy habits to infants. Nevertheless, the researchers emphasize that these findings are not meant as a criticism: modern families rely on these devices for work, healthcare, shopping, and communication.

Prioritize real-life interactions and healthy alternatives

Although scientists believe more evidence is needed, their report identifies several approaches that could help reduce the amount of time babies spend in front of screens. Spending more time outdoors can naturally replace screen time while promoting physical development and healthy vision. Similarly, keeping screens away during meals is said to encourage healthier eating habits, while offering non-digital toys creates more opportunities for learning and active play.

Regular face-to-face interactions with family members, caregivers, and peers also support balanced social development—findings confirmed by many years of child development research highlighting the key role of conversation and movement. “Screen time is deeply woven into the lives of many families throughout the day,” notes Carmen Clayton, professor of family and cultural dynamics at Leeds Trinity University and co-lead author of the study.

Given the limitations of current professional support, the researchers are calling on policymakers, healthcare professionals, and early childhood educators to collaborate on developing a risk assessment for screen time among infants. "The government needs to find better ways to engage with families regarding problematic screen use. It must also be sensitive to the fear of judgment that many parents face when discussing these issues," added Carmen Clayton.

A collective responsibility involving tech giants

Since parents’ digital habits strongly influence those of their babies, the study suggests that society as a whole must rethink its relationship with technology, rather than placing the blame solely on families. “This historical review is a wake-up call,” said Dame Andrea Leadsom, founder of the 1001 Critical Days Foundation. “The evidence increasingly suggests that screens offer limited benefits for babies and may pose significant risks during the first 1,001 days—the most critical period of human development. Parents should not be blamed for a problem they did not create.”

She continued: “Screens are now part of everyday life, and many families are navigating this challenge without the information and support they need. The responsibility cannot rest solely on their shoulders.” To address this in a practical way, the research group recommends that every family have access to a resource center like a Best Start Family Hub, offering reliable advice and logistical support during the early years.

Finally, a direct appeal is made to the tech industry. The full study, published in the scientific journal White Rose, urges these companies to be more honest in their marketing by stopping the practice of labeling their content as suitable for infants without solid scientific evidence. Helping parents navigate this digital world is considered essential to giving children the best possible start in life. For any medical questions, consult a qualified healthcare professional.
