Sensory play has become a popular concept in early years parenting, and it is genuinely backed by developmental science — though the reality is simpler and less expensive than the curated "sensory bin" trend on social media might suggest. Babies and toddlers are naturally driven sensory explorers, and creating opportunities for them to explore the physical world through their senses is one of the most developmentally valuable things parents can offer.
Healthbooq supports parents with practical, evidence-informed guidance on play activities that support early development, including sensory play ideas that use everyday materials and no specialist equipment.
What Sensory Play Supports
Sensory play engages multiple developmental systems simultaneously. Physical manipulation of materials (squeezing, pouring, mixing, pressing) develops fine motor skills and the hand strength and coordination that underpin later self-care and writing readiness. The language opportunities during sensory play are rich: describing textures, temperatures, and consistencies (rough, smooth, cold, slimy, heavy, light) builds vocabulary across sensory domains that is not easily developed through other activities.
Cognitively, sensory play provides a natural context for scientific thinking: children observe what happens when they mix two materials, what sinks and what floats, what happens when water is added to dry sand. This cause-and-effect exploration is precisely the kind of active investigation that builds early scientific reasoning. Emotionally and neurologically, sensory play that is self-paced and self-directed provides a grounding, regulating experience that many children — particularly those who are dysregulated or overwhelmed — find calming.
For Babies (Three to Twelve Months)
For young babies, the primary sense through which the world is explored is touch and proprioception (body awareness), with the mouth as the main exploratory instrument alongside the hands. Appropriate sensory activities for this age group focus on varied tactile experiences in safe, supervised contexts.
A simple sensory exploration activity for a baby who can sit supported: gather a collection of objects with different textures — a soft cloth, a textured rubber toy, a smooth wooden block, a cool metal spoon, a rough piece of hessian. Hold each one for the baby to grasp, mouth, and feel, narrating the experience. Texture books, which provide varied tactile surfaces within a safe, mouthable format, are excellent. Crinkle toys and toys with varied surface textures engage the sensory system effectively without any setup.
Water play — in a shallow basin or baby bath, with close supervision — provides one of the richest sensory environments available: temperature, resistance, splash sounds, and the compelling experience of something that can be moved but not held.
For Toddlers (Twelve to Thirty-Six Months)
Toddlers are ready for more immersive sensory experiences. Classic activities include: water play (pouring, transferring between containers, adding food colouring or toys); sand play (dry or wet, at the beach or in a sand tray); playdough made at home (safe if ingested in small amounts: 1 cup flour, half cup salt, half cup water, tablespoon oil, food colouring if desired); shaving foam or textured paint on a tray for marks and patterns; and simple sensory bins (containers filled with dried pasta, dried rice, dried lentils, or similar safe material, with spoons, cups, and funnels to explore).
Natural materials provide exceptional sensory play: a walk that involves deliberately collecting items (pine cones, leaves, sticks, stones) followed by arranging, sorting, comparing textures and sizes, and carrying the collection engages multiple systems at once. Outdoor messy play — jumping in puddles, touching bark, rolling in dry leaves — is sensory play in its most natural form.
Safety Considerations
Supervision is required for all sensory play involving small objects (choking risk), sand or dry materials (inhalation risk if poured near the face), water (drowning risk even in shallow water — a child can drown in a few centimetres), and food-based materials where quantity matters. Natural sensory play outdoors requires attention to hygiene — washing hands after handling soil, avoiding known contaminants.
For children with sensory sensitivities (some dislike certain textures, sounds, or touch) — which is more common in neurodivergent children but occurs in many children — gradual, pressure-free introduction to new sensory experiences is appropriate. Forcing engagement with textures that distress a child is counterproductive.
Key Takeaways
Sensory play — activities that engage one or more of the senses (touch, sight, sound, smell, taste, proprioception, vestibular sense) — supports sensory integration, cognitive development, language development, and fine and gross motor development across the early years. It does not require commercial products or equipment; the most effective sensory play uses everyday materials. For babies, sensory exploration is largely driven by the mouth and hands; for toddlers, it expands to whole-body immersive experiences. Supervision is required for all sensory play that involves small objects, liquids, or anything the child might put in their mouth in unsafe quantities.
