The science is sobering but not damning: what matters most is not perfection, but the direction of small, consistent changes.
If you have ever looked up from your phone to find your toddler watching you with that particular, unblinking attentiveness they reserve for things they are quietly memorising, you are not imagining the significance of the moment. Researchers who study early childhood cognition are clear on this point: toddlers are not passive bystanders to parental phone use. They are active, industrious observers, cataloguing what trusted adults reach for, how long attention drifts, and what competes with their face for a grown-up's gaze. The good news is equally clear: the research points to direction of change, not perfection. A handful of reliable, phone-free daily rituals, particularly those involving shared play with simple, open-ended objects, produces measurable developmental benefit.
That is the honest summary. Everything that follows explains why the science lands where it does, and what you can practically do about it, without any need to feel that the time already spent scrolling has caused irreversible harm.
Andrew Meltzoff and Patricia Kuhl's decades of research on infant learning established something that now feels almost obvious once you hear it: babies and toddlers learn primarily by imitating trusted adults. From the first weeks of life, the human brain is oriented towards the faces and behaviours of caregivers, treating them as the most reliable guide to how the world works and what is worth attending to. Alison Gopnik frames this with characteristic vividness: the young child is a natural scientist, running experiments and building models of adult behaviour long before she can articulate a single hypothesis. When that scientist observes her primary caregiver reaching, repeatedly and automatically, for a small glowing rectangle in moments of pause or transition, she files the observation carefully. Devices, her developing mind concludes, are what people do.
What Meltzoff and Kuhl's research tells us
Infants as young as six weeks imitate facial expressions and actions performed by a trusted adult. By toddlerhood, this imitative drive extends to habits, routines and emotional responses. The caregiver is not merely a source of care but a living curriculum.
Jenny Radesky's observational studies, including a widely cited piece examining families at fast-food restaurants, found that caregivers absorbed in their phones showed markedly reduced verbal and non-verbal responsiveness to their children. Interactions became shorter, flatter and more reactive rather than warm and initiated. Sheri Madigan's longitudinal work extended this finding across time, identifying associations between parental screen habits and toddlers' own screen-time trajectories: children tend to mirror the media habits modelled for them. Researchers use the term technoference to describe the way device interruptions fracture parent-child interaction, and the cumulative effect of many small fractures across a day is what concerns developmental scientists.
This matters partly because of what Betty Hart and Todd Risley established in their foundational language research: the quantity and quality of adult talk directed at young children has profound consequences for vocabulary, literacy and long-term educational outcomes. Every mealtime or play session where a phone draws a parent's gaze is a mealtime or play session with fewer words, fewer responsive turns and a thinner conversational texture.
Kathy Hirsh-Pasek and Roberta Golinkoff's research on talk-rich, responsive play is unambiguous on one crucial point: it is not exposure to words that builds language, but contingent, back-and-forth conversation. The serve-and-return structure, where a child initiates and an adult responds and then the child responds again, is the mechanism through which vocabulary is acquired and syntax begins to take shape. Dana Suskind's work, alongside Harvard's broader research on early brain development, identifies these conversational volleys as essential infrastructure, not enrichment extras.
When a parent glances at a phone mid-sentence or mid-play, the conversational thread breaks. The child's serve goes unreturned. Over thousands of such moments across the early years, the cumulative gaps in interaction can affect language outcomes: not because any single moment is catastrophic, but because the pattern shapes the texture of the child's daily experience of being talked with.
Hirsh-Pasek and Golinkoff on what actually builds language
Contingent, responsive conversation, not mere word exposure, is the engine of vocabulary acquisition. Children need their communicative bids answered. A screen absorbing a parent's attention is a bid that goes unanswered.
Toddlers do not yet regulate their own emotions independently. They co-regulate with caregivers, borrowing the adult's calm, focused presence to manage states that would otherwise overwhelm them. Lev Vygotsky's zone of proximal development captures this scaffolding dynamic, and Laura Berk's work on self-regulation shows concretely how attentive adult presence supports a child's developing capacity to cope with frustration, transition and uncertainty. Jaak Panksepp's affective neuroscience adds a further dimension: the PLAY system is deeply social, and play that includes an attuned, responsive adult activates developmental circuits that solitary or screen-mediated play simply does not reach.
When a parent's attention is frequently divided, the toddler loses that scaffold at precisely the moments she most needs it. Dimitri Christakis's work echoes this concern. None of this is to say that modern life permits constant, undivided presence; it manifestly does not. But it does mean that the quality of attention during available windows matters enormously.
Jean Piaget's account of the sensorimotor and preoperational stages reminds us that children aged one to four understand the world primarily through observation and direct action, not instruction. A child who regularly sees caregivers reach for a device in moments of boredom, transition or mild stress learns, wordlessly and efficiently, that this is the default human response to those states. The lesson is absorbed before she has the language to question or contextualise it.
Carly Dauch and Leanne Sosa's research on toy complexity offers a useful counterpoint: simple, open-ended objects, a set of wooden blocks, a shape sorter, a skittles set, hold children's attention more sustainably and more creatively than complex, high-stimulation alternatives. The same principle applies to adults. The pull of the phone is partly a pull towards complexity and novelty. A simple, satisfying game shared with a child can interrupt that pull effectively.
Maria Montessori's principle of the prepared environment holds that children's behaviour is shaped profoundly by what is physically available and within reach. Friedrich Froebel, whose philosophy underpins much of modern early years education, believed in purposeful, material-rich play as the primary medium of learning. Together, these traditions suggest a practical strategy: make the right choice as automatic as the wrong one. If a basket of simple wooden toys sits beside the sofa, it can be reached for in the same unthinking moment that the phone currently is.
Jeffrey Trawick-Smith and Anthony Pellegrini both identify adult participation in play as multiplying its developmental value considerably. The swap works best, then, not when a parent places toys nearby and retreats, but when they join in: rolling a ball, stacking a tower, taking a turn at a simple game. Ten minutes of that, reliably repeated, has more developmental weight than an hour of parallel presence with a phone in hand.
Jaques of London's collections are a sensible place to build such a basket. The wooden toys range includes exactly the kind of open-ended, tactile objects that Dauch and Sosa's research identifies as developmentally rich, and the traditional games collection contains games that work for adult and child together.

Conditions do not need to be perfect; they need to improve in a consistent direction. A single daily ritual, ten minutes of shared play with no phone visible, matters when it becomes a reliable pattern rather than an occasional gesture.
Jaques of London was established in 1795 on a premise that remains quietly radical: that simple, well-made objects, shared between adults and children, create moments worth returning to. The company that gave the world croquet in 1851 and the Staunton chess set in 1849 has always understood that the best play is unhurried, tactile and held in common. If you are looking for a place to begin building those daily rituals, the full range is a good place to start.
The research in one sentence
No study asks parents to be present every moment; all of them point to the same conclusion: consistent, attuned, phone-free pockets of shared play produce outcomes that neither occasional perfection nor constant distraction can replicate.
It is not. Radesky and Madigan's research concerns patterns, not episodes, and patterns can shift. What matters developmentally is not a flawless history but a reliable present: predictable pockets of undivided attention, shared play and responsive conversation woven into each day. Children are remarkably good at updating their working model of a relationship when that relationship becomes warmer or more present. If the phone is a genuine work tool, consider whether visual cues, a particular spot at the desk or a small agreed signal, can help distinguish work time from play time in a way your toddler can begin to internalise.
Dauch and Sosa's research suggests that children surrounded by high-stimulation, complex toys can become habituated to novelty and find simpler objects temporarily uninteresting. The solution is not to add more elaborate toys but to reduce the competition and introduce simple objects gradually, with your own obvious enjoyment as the draw. A wooden puzzle worked on together, a set of skittles knocked over with great ceremony, a shape sorter that you pretend to find genuinely baffling: your enthusiasm is the most powerful advertising available to a toddler. Hirsh-Pasek and Golinkoff's work confirms that it is the social, conversational quality of play that makes it compelling, not the sophistication of the object. Start small, start with yourself present, and let the phone be elsewhere for that window.
The content matters less than the behavioural pattern your child observes. What a toddler registers is not the nature of what is on your screen but the posture, the duration, the withdrawal of gaze and the emotional flatness that tend to accompany absorption in any phone use. That said, Radesky's research notes that emotionally activating content, including social media that provokes irritation or anxiety, can affect parental mood and therefore the quality of subsequent interaction. So while no category of phone use is innocuous from a modelling perspective, content that heightens your stress may have a secondary effect on your availability even after you put the phone down. The simplest heuristic remains: if your child is present and the moment is a play or mealtime window, the phone is better out of sight entirely.
The most effective approach is to make it a shared project rather than a critique. Framing the conversation around what you both want for your child, rather than what your partner is doing wrong, shifts the dynamic considerably. You might share one or two of the findings here, lightly, not as evidence for a prosecution but as something you found interesting and want to think about together. Practically, agreeing on a specific phone-free ritual, a daily game after dinner or a basket of toys kept near the table that both adults visibly reach for, makes the change structural rather than dependent on constant self-monitoring. Montessori's prepared environment principle applies here too: if the phone is in a different room and a skittles set is on the floor, the easier choice changes for everyone.
