Most toy design starts from a default assumption: the child using this product processes sensory input, social cues, and instructions in roughly the same way. That assumption works for a significant portion of children — and fails a significant portion too.
Approximately 15–20% of children are neurodivergent in some way, whether through ADHD, autism spectrum conditions, sensory processing differences, dyslexia, dyspraxia, or other profiles. Yet the vast majority of play products are designed around a neurotypical sensory and interaction baseline. The result is not just a missed market — it is a design gap that leaves many children without products that genuinely work for them.
This post is about closing that gap. Not through surface-level adaptations, but through design decisions that are rigorous, intentional, and grounded in how different children actually play.
The problem with "sensory-friendly" as a label
The term "sensory-friendly" has become a marketing shorthand, often applied to products that have simply removed loud sounds or rough textures. That is a starting point, not a design strategy.
Sensory processing differences are not uniform. A child with sensory-seeking behaviour needs more input — more texture, more resistance, more feedback. A child with sensory-avoidant behaviour needs the opposite. A single product cannot serve both profiles equally, which means the first design decision is understanding which user you are designing for — and being honest about that in how the product is positioned.
This requires moving beyond the label and into specifics: What sensory channels does this product engage? At what intensity? How predictable is the feedback it delivers? Can the child modulate it themselves?
Predictability as a core design value
For many neurodivergent children, unpredictability in a product is not a feature — it is a barrier. A toy that produces random sounds at random intervals, or whose interactive elements trigger inconsistently, creates anxiety rather than engagement.
Predictable cause-and-effect relationships are a foundational design principle for inclusive play products. When a child presses a button, the response should be consistent, proportionate, and immediate. This is good interaction design in any context — but it is non-negotiable in products aimed at children with autism or sensory processing differences.
Predictability also applies to physical properties. Materials that behave consistently — wood that always feels the same, mechanisms that always engage at the same resistance — give children a reliable sensory experience they can return to and build confidence with.
Designing for self-regulation, not just engagement
Neurotypical toy design often optimises for sustained engagement — keeping a child's attention as long as possible. For children with ADHD or sensory processing differences, a different design goal is often more appropriate: supporting self-regulation.
Self-regulation means the child can manage their own sensory and emotional state while using the product. This points toward specific design decisions:
Exit affordances. The product should have clear stopping points and natural pauses built into its interaction model. A play experience with no natural breaks makes it harder for children who struggle to disengage.
Adjustable stimulation. Where possible, let the child control the intensity of the experience. Volume controls, resistance levels, and modular complexity all give children agency over their sensory environment rather than subjecting them to a fixed one.
Repetition as a feature. Many children with autism or ADHD find deep comfort and focus in repetitive interaction. Design systems where repetition is rewarding rather than penalised — where the tenth engagement with a mechanism is as satisfying as the first.
The instruction problem
Most toy packaging assumes a child can read, follow sequential steps, and interpret diagrams. For children with dyslexia, ADHD, or processing differences, dense written instructions are a significant barrier — often encountered before the play experience even begins.
Good inclusive design treats the product itself as the instruction manual. Affordances should be clear enough that the first interaction is intuitive, not learned. Colour, shape, and physical fit should communicate how components connect or how mechanisms work without requiring the child to reference external guidance.
Where instructions are unavoidable, design them with visual sequencing, high contrast, and minimal text. Pictographic step-by-step guides are not a concession to accessibility — they are better communication design for every child.
What inclusive design does for the whole product
There is a tendency to treat neurodivergent design as a constraint — an additional requirement that narrows the design space. The evidence suggests the opposite.
Products designed for sensory clarity tend to be better products overall. Clear affordances benefit all children. Predictable feedback loops create more satisfying interactions across the board. Adjustable complexity extends the play life of a product across a wider developmental range. Reduced sensory overwhelm benefits children in noisy, busy environments regardless of their neurotype.
This is the curb-cut effect applied to play design: features developed for a specific need end up improving the experience for everyone.
The implication for product designers is practical. Designing for neurodivergent play does not require a separate product line or a specialist brief. It requires asking more precise questions during concept development: Who is the sensory baseline we are designing to? How predictable is every interaction this product delivers? What does the child who is overwhelmed do with this product — and is that outcome designed, or accidental?
A starting framework
When evaluating a play product for inclusive design, I find it useful to assess across four dimensions:
Sensory clarity — Is the sensory output of this product predictable, proportionate, and appropriate for the target sensory profile?
Interaction legibility — Can a child understand how to use this product without external instruction, through affordance alone?
Self-regulation support — Does the product give children agency over their level of stimulation, and are there natural pauses built into the experience?
Repetition value — Is sustained or repeated interaction with this product rewarding, or does the experience degrade quickly?
These are not neurodivergent-specific criteria. They are good design criteria. The difference is that for neurotypical children, gaps in these areas are inconveniences. For neurodivergent children, they are the difference between a product that works and one that does not.
Designing for neurodivergent play is not about adding an accessibility layer to an otherwise finished product. It is about building a more honest, precise understanding of how children — all children — actually interact with the things we make for them.
That precision makes better designers. And it makes better products.
