Infant Screen Time Linked to Autism-Like Signs: AIIMS Study Raises Fresh Concerns for Parents

A new AIIMS Delhi study has raised serious concern about infant screen time and early childhood development. According to reports, researchers found that children exposed to higher screen time before the age of one were more likely to show autism-like signs by age three. The study also found that children with autism spectrum disorder, or ASD, had earlier and more problematic digital media use, higher sleep problems, and lower physical activity compared with peers.

The findings do not prove that screens alone “cause autism.” That distinction is extremely important. Autism is a neurodevelopmental condition influenced by many factors, including genetics and early brain development. But the AIIMS findings strengthen a growing concern among doctors: too much screen exposure during infancy may interfere with the real-world social interaction, eye contact, language exposure, movement, and caregiver bonding that babies need most.

What the AIIMS Study Found

The AIIMS Delhi study was conducted on 250 children aged three to six years, including 150 children with autism and 100 children with typical developmental milestones. Researchers found that children with autism had higher media-addiction scores, lower sleep scores, and lower physical activity scores. The study is currently in the process of publication.

Dr Sheffali Gulati, professor of pediatric neurology at AIIMS Delhi, said the findings could help develop ASD-specific screen-time guidelines and caregiver counseling norms. She also warned that exposing infants to screens before 18 months “can have consequences.”

India Today’s report on the same findings noted that children exposed to higher screen time before age one were more likely to show autism-related signs by age three, and that doctors recommend children under 18 months ideally should not be exposed to screens at all.

The Key Point: Screens May Replace Human Interaction

The most important part of this discussion is not simply the screen itself. It is what screen time replaces.

A baby’s brain develops through repeated human interaction. Eye contact, facial expressions, touch, sound, gestures, imitation, play, shared attention, and emotional response all help shape early communication. When a baby looks at a caregiver, hears language, responds to tone, and receives feedback, the brain is learning social connection.

Screens cannot fully provide that.

India Today quoted Dr Gulati explaining that early childhood depends on eye contact, back-and-forth sounds, gestures, and play, and that these small interactions help wire the brain during the first years of life.

This is why doctors worry about phones and tablets being used to feed, distract, soothe, or silence infants for long periods. A cartoon may keep a baby still, but stillness is not the same as development.

Does Screen Time Cause Autism?

This is the question many parents will ask first.

The careful answer is: the study shows an association, not simple proof of direct causation.

Autism spectrum disorder is complex. It has strong biological and genetic components. Environmental factors may influence development, but it would be inaccurate and unfair to say that a parent caused autism by letting a child watch screens.

The better interpretation is this: high screen exposure in infancy may be linked with autism-like features, delayed social communication, sleep disruption, reduced activity, and fewer real-world interactions. In some children, excessive screen time may worsen developmental vulnerabilities or make early signs harder to notice.

That difference matters. The message should not be guilt. The message should be awareness and prevention.

Why the First 1,000 Days Matter

The first three years of life are a critical period for brain development. During this time, the brain is highly flexible, responsive, and shaped by experience.

Dr Gulati emphasized that the first 1,000 days, from pregnancy to age three, are crucial for brain development. Early identification of autism signs allows intervention to begin sooner, which can improve outcomes. After age three, patterns in the brain may become harder to change.

This is why pediatricians place so much importance on early milestones, including eye contact, response to name, babbling, gestures, pointing, pretend play, and social smiling.

When screens dominate a baby’s daily routine, parents may miss subtle developmental delays. At the same time, the child may receive less practice in the very skills that support communication.

Early Signs Parents Should Watch For

Parents should not panic over every delayed milestone, but they should stay alert. Early signs that may need medical evaluation include poor eye contact, not responding to name, delayed speech, loss of acquired words, limited gestures, lack of pointing, repetitive behaviors, unusual fixation on parts of toys, toe walking, hand flapping, or limited interest in social play.

Dr Gulati noted that signs can be detected even in the first year of life, such as lack of eye contact, not responding to name, delayed speech, or loss of acquired language. She also explained that autism is a spectrum, meaning every child is different and symptoms vary widely.

A child showing one sign does not automatically have autism. But if several signs appear together, or if a parent feels something is not right, early screening is better than waiting.

What Global Guidelines Say About Infant Screen Time

The AIIMS findings align with international guidance that already discourages screen exposure for infants.

The World Health Organization says screen time is not recommended for infants under one year. For one-year-olds, sedentary screen time is also not recommended. For two-year-olds, sedentary screen time should be no more than one hour, and less is better. WHO also encourages reading and storytelling with caregivers during sedentary time.

MedlinePlus, a service of the U.S. National Library of Medicine, says children under age two should have no screen time and that videos aimed at very young children do not improve development despite advertising claims.

These recommendations are not about demonizing technology. They are about protecting the developmental needs of babies and toddlers.

Why Screens Affect Sleep and Activity

The AIIMS study found that children with autism had higher sleep problems and lower physical activity scores. This matters because sleep and movement are deeply connected to early development.

Too much screen time can delay bedtime, overstimulate the brain, reduce natural play, and replace crawling, walking, reaching, climbing, and exploring. For infants and toddlers, movement is not just exercise. It is how they learn balance, coordination, space, cause-and-effect, and body awareness.

WHO’s guidance also connects reduced sedentary screen time with active play and good-quality sleep, saying these patterns support motor and cognitive development in the first five years.

In simple terms, babies need faces, voices, floor play, sleep, touch, and movement more than they need videos.

Practical Advice for Parents

Parents do not need perfection. Modern parenting is exhausting, and many families use phones or TV to manage feeding, crying, housework, or work pressure. The point is to reduce dependency and rebuild healthier routines.

For babies under 18 months, avoid routine screen exposure except occasional video calls with family. For toddlers, keep screen time short, supervised, and interactive. Do not use screens as the main feeding tool. Avoid screens before sleep. Keep mealtimes screen-free. Turn off background TV. Replace passive watching with talking, singing, reading, naming objects, peekaboo, blocks, outdoor play, and simple household interaction.

The most powerful “educational content” for a baby is still a responsive human being.

What If a Child Already Had Too Much Screen Time?

Many parents may feel worried after reading this. The helpful response is not guilt; it is correction.

If a baby or toddler has been getting too much screen time, parents can reduce it gradually. Start with the easiest windows: no screens during meals, no screens before bedtime, no background TV, and no phone during parent-child play. Replace one screen session per day with a short book, music, toy play, or outdoor walk.

If the child shows speech delay, poor eye contact, reduced response to name, repetitive behaviors, or social communication concerns, schedule a developmental evaluation. Early therapy, parent-led interaction, speech-language support, occupational therapy, and structured play can make a meaningful difference.

The AIIMS Delhi study adds to growing concern that high screen exposure in infancy may be linked to autism-like signs by age three, especially when screens replace human interaction, sleep, physical activity, and social communication practice.

But the message must be balanced. Screen time does not automatically cause autism, and parents should not be blamed. Autism is complex and varies widely from child to child.

The safest takeaway is clear: babies and very young toddlers need less screen exposure and more real-world connection. The first years of life are built through eye contact, language, touch, movement, play, sleep, and caregiver response.

For parents, the best step is simple but powerful: put the screen down more often, talk to the child more, play more, read more, and seek early medical guidance if developmental signs appear.
