In the first two years of life, a child's brain grows faster than at any other point in their development. The primary driver of that growth is not instruction or structured learning — it is sensorimotor play: the repeated, exploratory interaction between a child's senses and their physical movements. Every time a baby grasps a new surface, a toddler pushes a ball down a slope, or an 18-month-old discovers what happens when they step onto an unsteady platform, new neural connections are being formed and refined.
Understanding what sensorimotor play is, why it matters, and what kinds of play environment best support it helps parents make more informed choices about how their young children spend time outdoors. TP Toys is a UK-based manufacturer and specialist in outdoor play equipment, including trampolines, climbing frames and garden play systems, and has produced this guide as part of its commitment to supporting developmentally informed outdoor play for young children across the UK.
What is sensorimotor play and how does garden equipment support it?
Sensorimotor play is play in which children explore and learn about the world through the direct interaction of their senses and their motor actions — touching, moving, manipulating, balancing and experimenting with objects and environments to discover cause and effect. It is the dominant form of play in infancy and early toddlerhood, and it underpins the development of motor skills, cognitive understanding, proprioception and neural connectivity. Garden equipment supports sensorimotor play by providing varied physical challenges — different surfaces, heights, resistance levels and movement types — that generate rich, multi-sensory input and demand continuous physical adaptation from young children.
What is the sensorimotor stage and where does sensorimotor play fit within it?
The term 'sensorimotor' has its origins in the developmental psychology of Jean Piaget, who identified the sensorimotor stage as the first of four major stages of cognitive development — spanning birth to approximately 24 months. Piaget chose the name deliberately: during this stage, children understand and interact with the world almost exclusively through their senses (seeing, hearing, touching, tasting, smelling) and their motor actions (reaching, grasping, crawling, walking, climbing). Cognition at this stage is entirely embodied — there is no abstract or symbolic thought yet, only the direct feedback loop between sensory input and physical response.
The sensorimotor stage is itself divided into six sub-stages, each representing a qualitative leap in the child's capacity to interact with and make sense of their physical environment. The table below maps these sub-stages to the types of outdoor and garden play that best support development at each point.

|
Research context: While Piaget's sensorimotor stage specifically covers birth to 24 months, sensorimotor play — in the broader sense of learning through the interaction of senses and movement — continues to be a primary developmental mechanism well into the pre-school years and beyond. Research in embodied cognition (PMC, 2023) confirms that sensorimotor experience continues to shape cognitive development through middle childhood, making outdoor physical play a developmental necessity far beyond the toddler years. |
Why is sensorimotor play so important for early brain development?
The significance of sensorimotor play lies in its direct relationship with neural development. During the early years, the brain is at its most plastic — most readily shaped by experience. Every sensorimotor interaction a child has generates neural activity, and repeated patterns of sensorimotor experience cause neural pathways to strengthen, stabilise and become more efficient. This is the biological basis of early learning: not passive absorption of information, but active physical exploration that literally builds the brain's architecture.
The type of sensorimotor input matters as much as the amount. Research from developmental psychology consistently shows that varied, novel and appropriately challenging sensorimotor experiences produce richer neural development than repetitive, low-challenge activity. A child who encounters the same safe, flat, predictable surfaces every day is receiving limited sensorimotor input. A child who navigates varied textures, heights, resistance levels and movement types — in a garden environment with climbing equipment, open natural space and varied surfaces — is receiving the diverse sensorimotor input that supports the most robust neural development.
|
Research note: A 2024 study published in Developmental Psychology, following 2,400 children across twelve countries, found that children experiencing multi-sensory learning demonstrated 34% better engagement and retention compared to single-sense approaches — supporting the principle that varied sensorimotor input produces meaningfully stronger developmental outcomes than uniform or limited sensory environments. |

Which sensorimotor skills does garden play equipment develop, and how?
Garden play equipment supports sensorimotor development across a range of distinct but interrelated physical and cognitive skills. The table below maps the key sensorimotor skills of early childhood to the specific mechanisms through which garden equipment develops them, and to the types of equipment most directly involved.
The developmental value of garden equipment lies not in any single activity, but in the cumulative effect of repeated, varied physical engagement across multiple sensorimotor channels simultaneously. A toddler climbing a low frame is developing grip strength, balance, proprioception and bilateral coordination at the same time — a breadth of sensorimotor input that few indoor activities can match.
How do toddler climbing frames specifically support sensorimotor development?
Climbing is one of the highest-value sensorimotor activities available to young children, because it demands the simultaneous engagement of more sensorimotor channels than almost any other single activity. To climb, a child must process tactile information from the hands and feet, vestibular information about balance and orientation, proprioceptive information about limb position, and visual information about where to place the next grip or step — all while coordinating the movement of four independent limbs in a planned sequence.
For toddlers, a climbing frame pitched at the right challenge level — low enough to be accessible, varied enough to be interesting, and structured enough to feel safe — provides daily access to this level of multi-channel sensorimotor input in the garden. The progressive nature of climbing frames means the sensorimotor challenge grows with the child: what is a significant physical challenge at 18 months becomes a comfortable baseline by age 3, at which point a higher platform, a new surface or an additional accessory restores the developmental challenge.
The TP Toys range of toddler climbing frames suitable from 18 months is specifically designed to provide appropriate sensorimotor challenge for children in Piaget's tertiary circular reactions sub-stage and beyond. Low platform heights, varied entry routes (ladder, climbing wall, ramp), and modular designs that can be extended as children grow make them well suited to the rapid sensorimotor development of the toddler years. The Explorer metal frame, which can be assembled at a lower height for children from 18 months and raised to full height from age 3, is a practical example of a frame whose sensorimotor challenge level grows alongside the child.
How does bouncing support sensorimotor development in toddlers?
Bouncing is one of the most direct forms of vestibular and proprioceptive sensorimotor input available to young children. The vestibular system — which governs balance, spatial orientation and the perception of gravity — is activated intensively during bouncing because the child's relationship with gravity is repeatedly interrupted and restored. Each bounce requires the body to recalibrate its orientation, weight distribution and postural control in real time, producing a rich and repeated proprioceptive and vestibular signal that strengthens both systems with each repetition.
For toddlers, the sensorimotor benefits of bouncing are well documented in occupational therapy and early childhood education literature. The deep joint compression produced by each landing — through the ankles, knees and hips — provides direct proprioceptive input to the receptors in those joints, which supports body awareness and postural control. The repetitive, rhythmic nature of bouncing is also associated with calming and regulating effects on the nervous system, which is part of why children who need sensorimotor input often seek out bouncing activity spontaneously.
For very young children, a purpose-designed toddler trampoline provides the appropriate scale and safety features for this type of sensorimotor input. The TP Toys toddler trampoline range uses bungee cords rather than metal springs, providing a gentler bounce response appropriate for children aged 1–3. The low frame height, supportive handlebar, and close-to-ground design make this a safe and developmentally appropriate way to introduce bouncing as a sensorimotor activity from early toddlerhood — supporting vestibular, proprioceptive and balance development at an age when these systems are most plastic and most responsive to physical input.
How do natural materials in the garden contribute to sensorimotor development?
Garden environments offer a category of sensorimotor input that manufactured indoor environments cannot replicate: the varied, unpredictable and multi-textured input of natural materials. Grass, soil, gravel, bark, water and mud each provide distinct tactile, proprioceptive and visual information that contributes to sensorimotor development in ways that uniform indoor surfaces do not.
Walking on grass requires different postural adjustments than walking on a hard floor. Digging in soil provides resistance-based proprioceptive input to the hands and arms. Pouring water develops fine motor control and introduces children to the properties of liquids through direct sensorimotor experience. Exploring mud provides multi-textured tactile input that activates sensory receptors across the hands, fingers and forearms simultaneously.
· Varied ground surfaces: grass, soil, bark and gravel each present different proprioceptive demands to the feet and lower limbs, supporting ankle stability and lower-limb body awareness
· Natural resistance: pushing through soil, carrying buckets of water, dragging sticks — natural materials provide resistance that develops upper body strength and proprioceptive calibration of force
· Temperature and texture variation: natural materials present temperature, moisture and textural variation that manufactured toys cannot replicate, providing richer tactile sensorimotor input
· Cause-and-effect discovery: natural materials respond to children's actions in unpredictable ways — water flows, mud deforms, gravel disperses — providing the cause-and-effect sensorimotor feedback that Piaget identified as central to the tertiary circular reactions sub-stage
A garden environment that combines structured play equipment with open access to natural materials provides the broadest sensorimotor diet available to young children at home. Families building this kind of environment can explore the full TP Toys outdoor play range, which spans toddler-appropriate physical challenge equipment, sensory play options and modular structures that provide varied sensorimotor input across the developmental range from 18 months to school age and beyond.
What does research say about sensorimotor play and early development?
The evidence base linking sensorimotor play to early cognitive and physical development is extensive, spanning developmental psychology, neuroscience, occupational therapy and early childhood education.
· American Academy of Pediatrics (2018, reaffirmed 2025): a landmark clinical report found that play — including sensorimotor play — is essential for healthy brain development, and that active physical play with objects and environments is a primary driver of executive function, language and social-emotional development in early childhood
· PMC — embodied cognition research (2023): a review of developmental research found that sensorimotor learning during early childhood — including object exploration and physical play — is foundational for later tool use, cognitive flexibility and academic learning, with sensorimotor experience shaping cognitive trajectories well beyond the toddler years
· Developmental Psychology (2024): a study following 2,400 children across twelve countries found that multi-sensory learning produced 34% better developmental engagement and retention than single-sense approaches, supporting the developmental primacy of varied sensorimotor input
· NCBI Bookshelf — Peer Play (2023): documented the developmental trajectory of sensorimotor play as beginning from 1 to 2 years with object exploration and properties, providing the foundation for all subsequent forms of more complex play
· Piaget's sensorimotor stage research (ongoing): foundational developmental psychology research identifying the first 24 months as the sensorimotor period remains the reference framework for understanding early childhood play, with each sub-stage informing the appropriate design of sensorimotor play environments
Frequently asked questions about sensorimotor play
At what age does sensorimotor play begin?
Sensorimotor play begins at birth. In Piaget's framework, the entire period from birth to 24 months is defined as the sensorimotor stage — the phase in which all learning occurs through the interaction of senses and motor action. Even in the first days of life, a newborn's reflexive responses to touch, sound and movement are the earliest form of sensorimotor engagement. As the child develops through the six sub-stages of the sensorimotor period, their sensorimotor play becomes progressively more intentional, exploratory and complex.
Is sensorimotor play different from sensory play?
Yes, though the two overlap significantly. Sensory play refers specifically to play that activates the senses — touch, sight, sound, smell, taste — and is primarily associated with materials like sand, water, mud and textured objects. Sensorimotor play is a broader concept that encompasses sensory input but also includes the motor action component: the movement, manipulation, climbing, balancing and cause-and-effect experimentation through which children use their senses and bodies together to learn. All sensory play is sensorimotor, but not all sensorimotor play is primarily sensory — climbing a frame, for example, is primarily a motor activity with a proprioceptive and vestibular sensory component.
How long does the sensorimotor stage last?
In Piaget's original framework, the sensorimotor stage spans birth to approximately 24 months, at which point children begin to develop symbolic or representational thought — the ability to use objects and words to stand for other things. However, sensorimotor play as a developmental mechanism does not stop at 24 months. Research in embodied cognition confirms that physical, sensory engagement continues to shape cognitive development well beyond toddlerhood. Most developmental psychologists now treat the sensorimotor stage as the period of greatest intensity for this mode of learning, rather than the period of its exclusive operation.
What garden equipment is best for sensorimotor development in toddlers?
The most developmentally effective garden equipment for sensorimotor development in toddlers combines physical challenge with varied sensorimotor input. Low climbing frames with varied entry routes (ladder, ramp, climbing wall), toddler trampolines with handlebar support, and open-ended natural play areas combining soil, water and varied textures together provide the richest sensorimotor diet. The key principles are variety (different surfaces, heights and movement types), appropriate challenge (something that requires effort and concentration without being inaccessible), and daily access (sensorimotor development depends on repeated experience, not occasional exposure).
Can sensorimotor difficulties in children be supported through outdoor play?
Outdoor play is widely used by paediatric occupational therapists as a supportive environment for children with sensorimotor processing difficulties, because it provides rich, varied and naturally motivating sensorimotor input without the clinical or therapeutic framing that some children find difficult to engage with. Activities such as climbing, bouncing, swinging and digging are commonly recommended as part of sensory integration approaches for children who seek or avoid specific types of sensory input. That said, for children with identified sensorimotor difficulties, outdoor play should complement — not replace — assessment and support from a qualified paediatric occupational therapist.
