New study renews concern over early digital exposure
New York, United States | June 2026
A new study has renewed concern about the impact of screen time on children under two years old, warning that early and frequent exposure to phones, tablets, televisions and other digital devices may affect key areas of child development. The findings add to a growing public health debate about how families, schools and health professionals should manage technology during the first years of life.
Early childhood is a critical period for brain development. During the first two years, children learn mainly through movement, eye contact, touch, play, imitation and direct interaction with caregivers. When screens replace these experiences for long periods, specialists warn that language, attention, emotional regulation and social learning may be affected.
The concern is not only the screen itself, but what it displaces. A baby or toddler who spends too much time watching videos may spend less time hearing spoken language, exploring objects, crawling, playing with caregivers or responding to real-world social cues. These everyday interactions are essential for building communication, memory, motor coordination and emotional security.
Researchers and pediatric specialists have repeatedly emphasized that children under two do not learn from screens in the same way older children or adults do. At this age, they need concrete experiences and human feedback to understand the world. Even educational videos may have limited benefits if they replace live interaction with parents, siblings or caregivers.
The study also points to possible risks in attention and behavior. Fast-moving images, constant sounds and highly stimulating content can condition young children to expect rapid changes in information. This may make slower real-world activities, such as reading, quiet play or conversation, less attractive over time.
Another concern involves sleep. Screen exposure, especially before bedtime, can interfere with rest patterns because light and stimulation may delay relaxation. Poor sleep in early childhood can affect mood, learning, growth and family routines, making screen habits an important issue for household health.
Experts generally recommend avoiding regular screen use for children under two, except for video calls with family members. This exception matters because video calls include real human interaction, facial expressions and emotional connection. Passive viewing, however, should be limited as much as possible during this stage.
For parents, the message should not be interpreted as guilt, but as guidance. Many families use screens occasionally to calm a child, complete household tasks or manage difficult moments. The key is to avoid making screens a constant substitute for play, conversation, affection and exploration.
Practical alternatives include reading aloud, singing, playing with simple objects, outdoor time, floor movement, drawing, stacking blocks and naming everyday items. These activities may seem simple, but they directly support language, motor skills and emotional development.
The debate also highlights the need for social support. Parents often turn to screens because they are tired, overworked or lacking help. Therefore, reducing screen exposure is not only an individual responsibility; it also requires better childcare support, family education and public health guidance adapted to real life.
Technology will remain part of family life, but early childhood requires special caution. For children under two, the strongest developmental tool is still human interaction. The new study reinforces a clear idea: during the earliest years, the best screen is often no screen at all.
