A new landmark study warns that screen time can significantly damage the development of children under two years old. The research, published in a major journal, indicates that early exposure to screens may impair cognitive and social skills.

Why this matters: With smartphones and tablets ubiquitous in modern households, the findings challenge common parenting practices. The study adds to growing concerns about the long-term effects of digital media on the youngest children.

The data draws from a large sample, but specific numbers were not detailed in the source. The research highlights a critical window in early brain development where screen exposure may be particularly harmful.

Looking ahead, these results could influence public health guidelines and parental recommendations. Pediatricians may need to reinforce existing advice to limit or avoid screen time for infants and toddlers.

Some experts caution that the study's observational nature cannot prove causation, and more research is needed to understand the mechanisms behind the findings.
