A landmark international study has found that regular screen time for children under the age of two could have lasting negative effects on their development, health and overall wellbeing.

Researchers say the first two years of life are critical for brain development, making face-to-face interaction and play far more beneficial than time spent on digital devices.

The review linked early screen exposure to delayed language development, reduced bonding with parents and caregivers, poorer sleep, overstimulation, eye health concerns and a higher risk of childhood obesity. Experts also warned that using screens to comfort babies may replace essential human interaction.

Researchers are calling on governments to review existing screen-time guidelines and introduce stronger advice for parents, stressing that babies under two should not have regular intentional screen time.

The study also urges technology companies to stop promoting digital content as suitable for infants and encourages families to prioritise talking, reading and playing together during a child’s early years.
