Digital devices have become permanent fixtures in modern households, often serving as convenient tools to soothe or entertain infants. However, a comprehensive new study led by researchers at Loughborough University in the UK warns that this convenience may come at a significant cost. According to a world-first systematic review, intentional screen time for under-twos is linked to a range of developmental concerns, prompting experts to call for an immediate shift in how families, healthcare professionals, and technology companies approach early childhood digital exposure.

Understanding the First 1001 Days and Digital Exposure
The period from conception to a child’s second birthday—often referred to as the first 1001 days—is universally recognized as a critical window for brain development. During this time, neural pathways are formed at an unprecedented rate, heavily influenced by the infant’s environment and interactions with caregivers. When screens are introduced during this vulnerable period, they fundamentally alter the nature of these early experiences.
The research, commissioned by the 1001 Critical Days Foundation and conducted by the interdisciplinary Action on Digital Device Immersive Conditions Team (iADDICT), analyzed global peer-reviewed studies alongside insights from 174 UK parents. The iADDICT group, which includes experts from Loughborough University, the University of Leeds, Leeds Trinity University, and Aston University, found that digital media use—particularly via televisions, mobile phones, and tablets—is now pervasive during the first two years of life. Despite existing recommendations from the World Health Organization and the American Academy of Pediatrics advising against screen time for this age group, the data shows these guidelines are routinely exceeded globally.
Identifying the Developmental Concerns of Screen Time for Under-Twos
The systematic review moves beyond mere correlation to highlight specific areas of child development that are negatively impacted by early and regular screen use. While the review does not establish direct causal links between screen use and specific clinical developmental conditions, the associations are stark and warrant serious attention from parents and practitioners alike.
Cognitive and Social Development Risks
One of the primary developmental concerns associated with screen time for under-twos is the displacement of vital face-to-face interaction. Babies learn language, emotional regulation, and social cues by watching and responding to live human faces. When a tablet or television takes the place of a caregiver, opportunities to bond are significantly reduced. The research indicates that this can lead to limited language development and an increased reliance on devices for emotional regulation. Furthermore, screen time replaces essential play with peers and caregivers, hindering the development of critical social skills.
Physical Health and Wellbeing Impacts
Beyond cognitive and social delays, the Loughborough University-led study identifies several physical health risks tied to early screen exposure. Infants exposed to regular screen time face an increased risk of overstimulation, which can manifest as irritability and difficulty self-soothing. Sleep disturbances are also prominently linked to screen use, likely driven by the blue light emitted by devices and the sensory stimulation of the content. Additionally, the review highlights eye health implications and a concerning correlation between early screen time and an increased risk of childhood obesity, as sedentary screen time displaces physical movement.

Why Current Guidelines Are Falling Short in the UK
Despite the clear warnings from international bodies, the study reveals a troubling disconnect between policy and practice. Parents in the UK reported a significant lack of guidance from health professionals regarding screen use for babies. This gap leaves families navigating a complex digital landscape without the support they need.
Dr. Richard James, an expert in addictive behaviours from Loughborough University’s School of Sport, Exercise and Health Sciences, emphasized that previous policy assumptions regarding a lack of research specific to under-twos are inaccurate. The iADDICT review successfully identified a substantial evidence base pointing to potential harms. To bridge the gap between evidence and practice, the researchers are calling for the creation of a standardized baby screen time risk assessment. Developed in collaboration with policymakers, healthcare workers, and early years practitioners, this tool could help identify emerging developmental vulnerabilities and guide families toward healthier, interactive alternatives.
Practical Strategies to Reduce Screen Time for Babies
While the data paints a concerning picture, the researchers also identified several evidence-based strategies that parents and caregivers can implement immediately to mitigate developmental concerns.
Prioritizing Nature and Non-Digital Play
Taking children outdoors to spend time in nature serves a dual purpose: it naturally prevents screen time and actively benefits physical development and eye health. Access to non-digital toys—such as blocks, books, and sensory items—is also highly beneficial. These types of toys require active engagement from the infant, fostering problem-solving skills and fine motor development in ways that passive screen consumption cannot.
Managing Mealtimes and Social Interactions
Mealtimes offer a critical opportunity for connection and the development of healthy eating habits. The review suggests that avoiding the use of screens during meals correlates strongly with healthier eating behaviors and prevents the distraction that often leads to overfeeding or poor food choices. Additionally, simply spending time in the physical presence of others—meeting, interacting, and playing with other people—provides the social scaffolding necessary for robust emotional and social development.
The Need for a Societal Shift in Screen Habits
The researchers are careful to note that the responsibility for reducing screen time among under-twos should not rest solely on the shoulders of parents. The review found a direct correlation between parent and caregiver screen time and baby screen time. However, in a society where digital screens are embedded in daily life—from working and buying groceries to accessing healthcare—passive screen exposure is often inevitable.
Rafe Clayton, of the University of Leeds, pointed out that problematic screen use among adults is common, yet the UK government currently fails to provide screen time guidelines for adults. As role models, unguided adults inadvertently teach babies to develop unhealthy relationships with screen devices. A societal shift is required, beginning with understanding adult screen time thresholds and implementing honest marketing practices from technology companies. Dame Andrea Leadsom, Founder of the 1001 Critical Days Foundation, described the review as a “wake-up call,” stressing that technology companies must stop promoting content as suitable for babies when the evidence points to the contrary. She advocates for universal access to Best Start Family Hubs where families can receive trusted, non-judgmental advice.
Conclusion and Next Steps for Parents and Practitioners
The recommendation from the Loughborough University-led iADDICT group is clear: under-twos should not receive any intentional, regular screen time. Any guidance suggesting that screen technology is suitable for “all ages” or promoting shared screen time for babies must be urgently reconsidered. As we continue to navigate the digital revolution, protecting the first 1001 days of life from the developmental concerns associated with screen time must become a public health priority.
Parents, healthcare providers, and policymakers must work together to foster environments that prioritize human interaction, physical play, and healthy boundaries with technology. By taking proactive steps today, we can support the healthy cognitive, social, and physical development of the next generation.
