Screens, Babies and the Communication Trap

Few topics generate as much debate as children and digital media. Parents are bombarded with advice, experts disagree on many issues, commercial interests shape the conversation, and social media ensures that everyone has an opinion. In this crowded environment, scientific voices are often drowned out or reduced to simplistic headlines.

For babies, however, the scientific picture is clear. Across major professional bodies and national public health authorities, including the American Academy of Pediatrics and national guidance in countries such as Australia, Canada, Ireland, France, Norway or Sweden, the recommendation is consistent: routine or intentional screen use should be avoided for children under two years of age. Early development depends primarily on reciprocal human interaction, movement, sensory exploration, play, conversation with adults and peers (responsive language). Replacing these experiences with screen-based activities, whether these are educational apps, videos, or television, is not recommended. This does not mean that an occasional video call with a grandparent or a brief incidental exposure is harmful. Rather, the guidance is that intentional screen use should not become a regular part of the daily routine for children under two years of age.

Unlike discussions about older children, where the effects of digital media are more content- and context-dependent, infancy represents a distinct developmental period. At this stage, there is no rigorous evidence that intentional screen use provides developmental benefits, and there is strong evidence that the real-world interactions it displaces are fundamental to healthy development.

Yet communicating this message has proved surprisingly difficult. Scientists are frequently criticised for being alarmist or for making parents feel guilty when they draw a firm boundary. To me, this reveals a broader problem in developmental science and public health communication:

How should scientists communicate probabilistic developmental risk without producing either panic or permissiveness?

The tricky task of communicating about digital media in early childhood

Scientists working in the field of children and digital media are increasingly subject to a peculiar communicative demand. We are expected to issue guidance, but not sound prescriptive. We are expected to identify risk, but not provoke concern. We are expected to be clear, but also to surround every statement with enough caveats that nobody could possibly mistake it for a firm boundary.

The result is often a style of communication that attempts to alert and reassure simultaneously. Messages like:

“The evidence is complex, although the evidence also suggests a concern”. Or “We see this pattern but not every child exposed to a particular condition will experience the same developmental outcome”. Etc. We recommend caution, but we would not want to tell anybody what to do.

To me, this presents a contradiction that does not serve the field well. In trying to avoid alarming parents, researchers may have diluted clear recommendations to the point where they no longer provide meaningful guidance.

We need to ensure that we communicate science in ways that do not overstate certainty and never provoke unnecessary fear or panic. And we also need to ensure that parents get clear and practical guidance.

A scientist may arrive at a boundary (such as the one of two years of age) through years of evidence, qualification and debate, yet once that boundary is expressed clearly, it can be heard in the same register as a fear-inducing headline. The challenge, then, is to ask how a justified scientific position can remain recognisably evidence-based once it enters a communication environment that tends to reward alarm and simplification. Perhaps that is part of the problem we need to understand better.

The politics of “neutral” public communication

When scientists say that a one-year-old eating in front of an iPad may affect development, but also emphasize that parents should decide what is best, they may think they are being both careful and reassuring. But this can make the message less clear and the parent may experience such a message as instability and incoherence. In risk communication, this is a known communication problem where excessive hedging can create confusion. For example, Fischhoff argues that while uncertainty must be communicated, overly cautious or hedged messaging can undermine comprehension and decision quality, especially when audiences cannot distinguish between meaningful uncertainty and verbal hedging.

Neutrality is often treated as the most ethically responsible form of public communication. But in contexts where one behaviour is easier, commercially promoted, culturally normalised and technologically engineered for habitual use, neutral language does not enter a neutral environment.

The parent does not encounter the scientist’s cautious sentence in a vacuum. They encounter it alongside frictionless autoplay, infinite feeds, persuasive interface design, social normalisation, targeted marketing and devices that are already physically present in the home. Under such conditions, excessively neutral messaging may not function as neutrality but as passive endorsement of the behavioural default.

So scientists have decided to name a boundary: the two-year threshold. At the same time, they have tried to acknowledge why parents use screens, offer practical alternatives, distinguish infancy from later childhood, and draw attention to the influence of adults’ own media habits.

Will some parents still experience that message as uncomfortable, worrying or even frightening? Yes. But perhaps discomfort is not, in itself, evidence that the communication has failed?

Public health advice cannot promise that every child exposed to a risk will be harmed, nor that every child who avoids it will thrive. That is not how developmental science works. But uncertainty about individual outcomes does not make population-level guidance meaningless. We routinely make recommendations on the basis of probabilities and precaution, especially during periods of rapid development.

The greater danger may be that, in trying so hard not to worry parents, scientists stop saying clearly what the evidence supports.

For infants and deliberate screen exposure, the guidance can be both empathetic and unambiguous: the first two years are a period in which human interaction, movement, play and responsive communication should remain the developmental default. Screens should not replace them.

To me that is not alarmism but guidance.
