The people who design the world's most compelling digital products often choose wooden bricks, open-ended games and unstructured outdoor time for their own young children, and the developmental science behind that choice is clearer than ever.
The engineers, designers and executives who build the platforms most likely to occupy a young child's morning are, by several well-documented accounts, among the strictest screen-limiting parents in the world. This is not coincidence, and it is not hypocrisy. It is, in large part, informed caution: people who understand precisely how attention-capture works in software tend to want something different for a three-year-old at a critical period of neural development. The short answer to why is this: the early years are irreplaceable for building language, executive function, emotional regulation and the capacity for imaginative thought, and those capacities grow most robustly through face-to-face interaction, physical handling of objects and open-ended, child-directed play. Screens, however beautifully designed, do not reliably provide any of those things for children under five.
That conclusion is not opinion. It is the current consensus of the World Health Organization, the American Academy of Pediatrics and the UK Chief Medical Officers, all of whom recommend that children under two have virtually no screen exposure beyond video calls with family members, and that children aged two to five have no more than one hour per day of high-quality, co-viewed content. The guidelines share a common foundation: the under-five brain is not a smaller version of an adult brain. It is a qualitatively different organ, one that learns through touch, movement, social contingency and repetition in the physical world, not through passive reception of a two-dimensional stream.
What the WHO and CMO Actually Say
The World Health Organization's 2019 guidelines on physical activity, sedentary behaviour and sleep for children under five conclude that screen-based sedentary time should be limited or avoided entirely for the youngest age groups. The UK Chief Medical Officers echo this, noting that the quality of interaction during a child's waking hours matters as much as the quantity of movement. Both bodies emphasise that what replaces screen time is as important as the reduction itself.
Researchers Jenny Radesky and Dimitri Christakis have both published extensively on how media use during early childhood affects attention, language acquisition and the quality of caregiver interaction. Radesky's work draws attention to displacement: every hour a child spends with a screen is an hour not spent in the kind of contingent, responsive conversation that builds neural architecture. Christakis has found associations between high television exposure in early childhood and later attention difficulties, though he is careful to note that content quality and co-viewing make a meaningful difference.
The developing brain of a child under five is exquisitely sensitive to social contingency: the back-and-forth, serve-and-return exchange that Patricia Kuhl and Andrew Meltzoff have shown to be a primary driver of language and cognitive growth. When a caregiver's attention is divided by their own screen, the quality of the interaction available to the child drops sharply, and the child's learning environment diminishes with it.
Adele Diamond's research on executive function development makes a compelling case for physical, self-directed play as one of the strongest early interventions available to any parent. Executive function, the cluster of skills encompassing working memory, cognitive flexibility and inhibitory control, predicts academic and social outcomes more reliably than early academic instruction. It develops through exactly the kind of play that screens tend to displace: building, sorting, pretending, negotiating rules with another child and tolerating the productive frustration of a puzzle that does not immediately yield.
Carly Dauch and colleagues published findings showing that toddlers engaged in deeper, more sustained and more creative play when offered fewer toys at a time, a result with direct practical implications for how families arrange their homes. The research aligns with Maria Montessori's insight that a carefully prepared, uncluttered environment with purposeful objects invites concentration and independent exploration in ways that overstimulating environments do not.
Adele Diamond on Executive Function and Play
Diamond's longitudinal and experimental work consistently identifies physical play, particularly play that requires children to hold rules in mind and inhibit impulse, as a primary driver of prefrontal cortical development. She argues that the erosion of such play from early childhood environments has measurable cognitive costs, and that restoring it is among the most evidence-based things a parent or educator can do.
Kathy Hirsh-Pasek and Roberta Michnick Golinkoff, whose body of work on playful learning is among the most cited in developmental psychology, draw a clear distinction between directed instruction, passive entertainment and what they call guided play: experiences that are child-led but scaffolded by a responsive adult or an inherently open-ended object. A set of wooden blocks, a simple matching game, a puzzle with satisfying physical pieces: these are not nostalgic affectations. They are environments for thinking. Because they do not do anything on their own, the child must do the doing, which is precisely the point.
Jeffrey Trawick-Smith's TIMPANI study evaluated which types of toys produced the highest quality play in preschool settings. Open-ended construction materials and simple classic games consistently outperformed single-function electronic toys on measures of creativity, problem-solving and language use during play. A wooden puzzle or a set of classic skittles does not expire, does not require charging and does not reward passive watching. It rewards engagement.
At Jaques of London, established in 1795 and the world's oldest games company, the philosophy has always been that a well-made object invites a child's imagination rather than replacing it. The educational toys collection is built around exactly this principle: materials and games that grow with the child, demand genuine participation and offer the kind of open-ended challenge that builds rather than consumes attention.
Hart and Risley's landmark research established that the quantity and quality of language a child hears in the first three years of life has profound and lasting effects on vocabulary, reading and academic achievement. Dana Suskind, building on that foundation, has shown that the critical variable is not passive exposure to words on a screen but conversational turns: the child speaks, the adult responds, the child speaks again. A screen cannot participate in that exchange. A wooden toy, manipulated jointly by a parent and child, almost always can.
Anna Sosa's research specifically compared language produced during play with electronic toys, traditional toys and books. Electronic toys generated the least parent-child conversation of the three conditions. Books and traditional toys produced richer, more varied and more responsive verbal exchange. The implication for parents is direct: the toys that sit quietly and wait for a child to do something with them are, paradoxically, the ones most likely to fill a room with language.
Peter Gray, Jaak Panksepp and Sergio Pellis have each, from different disciplinary angles, argued that unstructured, self-directed play is not a luxury of childhood but a biological necessity. Panksepp identified PLAY as one of the primary emotional systems of the mammalian brain, distinct from other drives and essential for healthy social and emotional development. Gray's historical analysis suggests that the decline of free play over recent decades correlates with rising rates of anxiety and depression in young people, a correlation he argues is causal, not incidental.
Ellen Sandseter and Mariana Brussoni have made the case for risky, physical play specifically, arguing that the mild uncertainty involved in climbing, balancing and rough-and-tumble games helps children calibrate their own risk perception and build resilience. A screen offers neither physical challenge nor genuine uncertainty: the outcome is always, at some level, predetermined by the designer. The wooden toys range at Jaques includes objects designed to be handled, thrown, stacked and knocked over, precisely the kind of open physical engagement that developmental psychologists consistently endorse.
The evidence is clear, but guilt is rarely a useful motivator for change, and most families are navigating real constraints: working hours, childcare gaps and genuinely exhausted parents who need ten minutes to cook dinner. The goal is not perfection. It is gradual, sustainable rebalancing. A few principles help:
Hirsh-Pasek and Golinkoff on Playful Learning
Their research distinguishes sharply between entertainment, which passes time, and playful learning, which builds minds. The key features of genuinely developmental play are that it is active, engaging, meaningful, socially interactive and iterative. Open-ended physical toys and classic games meet all five criteria. Most screen content for young children meets, at best, two.
The honest answer is that the research does not support a simple binary. A single daily video call with a grandparent is not equivalent to two hours of fast-paced cartoon content, and context, content quality and whether a caregiver is present all make a genuine difference. What the evidence does show consistently is that high volumes of screen time in the under-five years displace the interactions and physical experiences that are hardest to recover later: serve-and-return language exchanges, tactile exploration, unstructured imaginative play and the development of executive function. Balance is the right frame, but it is a balance that many families currently hold at the heavier end, and the case for shifting it is strong.
Not remotely. The brain's plasticity in the early years is the same quality that makes excessive screen time a concern: it also means that positive change takes hold quickly. Most children who are offered genuinely engaging physical alternatives, particularly when a parent plays alongside them initially, will adapt readily. The transition is usually easier than parents expect, especially if new toys are introduced with enthusiasm and the child is not simply left alone with them. Piaget's insight that children construct knowledge through active manipulation of the world around them applies at every point in the early years, not only from birth.
The key is open-endedness. A toy that can be used in only one way will be exhausted quickly. A toy that invites a child to make decisions, construct something, sort by category or engage in pretend narrative will hold attention for far longer, and will hold it differently: the child is generating the engagement rather than receiving it. Trawick-Smith's TIMPANI research identified construction materials, simple games with rules and objects that invite physical manipulation as the highest performers on sustained, creative engagement. Look for toys with few instructions and many possibilities.
The developmental case for them rests on properties that have nothing to do with price: they are open-ended, they require physical interaction, they do not provide their own stimulation and they tend to invite adult participation. All of those features are associated with richer language, deeper play and stronger cognitive outcomes. Durability is a practical argument too: a well-made wooden toy from a maker with Jaques London's heritage, now in its third century of making play objects, will outlast many electronic alternatives and can be passed between siblings or generations without obsolescence. The investment calculus looks different once longevity is included.
Britain's oldest toy maker. Every toy open-ended, wooden, and built for exactly the kind of play the research recommends.
