Supporting sensory development at 12–18 months
Sensory development in a 12-to-18-month-old is supported through rich everyday play that feeds touch, movement, balance, sight, sound, taste and smell — messy play, safe climbing, songs and varied food textures, all done with you and led by your child. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.
In this answer 5 sections
Between twelve and eighteen months, your toddler is busy gathering the world through touch, movement, sound and sight — and the most powerful sensory support is simply rich, everyday play with you.
In short
You support sensory development in a 12-to-18-month-old through everyday, hands-on play that feeds all the senses — touch, movement, balance, sight, sound, taste and smell. At this age your toddler learns by doing: squishing, climbing, pouring, tasting and exploring. You don't need special equipment — messy play, safe climbing, songs, and varied textures during meals and bath time do beautifully. Follow your child's lead, keep it playful and unhurried, and let them set the pace.
Simple ways to support each sense
- Touch (tactile) — offer different textures to explore: warm and cool water, dough, soft fabric, dry rice or pasta in a tray, cooked vegetables on the plate. Let little hands get messy.
- Movement & balance (vestibular & proprioception) — encourage safe climbing on cushions, gentle swinging, rocking, dancing, crawling through tunnels, and walking on different surfaces like grass, sand or a rug.
- Sight — play peek-a-boo, point to and name things you see together, look at simple picture books, and use rolling balls and stacking toys.
- Sound — sing songs and rhymes, name household sounds, bang pots, shake a rattle or rice-filled box, and pause to let your toddler 'reply'.
- Taste & smell (during meals) — keep mealtimes calm and let them touch, smell and self-feed a variety of safe textures and flavours without pressure.
- Follow their lead — notice what your child enjoys or avoids, and let their curiosity guide the play. Short, frequent moments work better than long sessions.
Messy play, water play and outdoor time are some of the richest sensory experiences there are — and the warmth of doing them with you is what makes them count.
A gentle note on differences
Toddlers vary hugely in what they enjoy. Some love mess; some are cautious. That alone is normal. It is worth a friendly developmental check, though, if your child is consistently very distressed by everyday textures, sounds or movement, strongly avoids all messy or new sensory play, seeks intense input in a way that affects daily routines, or isn't yet exploring objects with hands and mouth. These are reasons to ask — not reasons to worry.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form. If you'd like reassurance about your toddler's sensory and overall development, a clinician can build a clear developmental profile and, where helpful, shape playful sensory support through occupational therapy. You can also explore Pinnacle Blooms Network for guidance built around your child.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for consistent strong distress with everyday textures, sounds or movement, avoidance of all messy or new sensory play, intense sensory-seeking that disrupts routines, or not yet exploring objects with hands and mouth — friendly reasons to ask for a check.
In everyday life
Set up a simple texture tray — dry rice or cooked pasta in a shallow dish — and let your toddler scoop, pour and squish freely. Sit with them, name what they feel, and let it be messy with no goal but play.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
What is the best sensory activity for this age?
There's no single best one — variety matters most. Messy play, water play, safe climbing, songs and exploring different food textures together all feed your toddler's senses. Follow what your child enjoys and keep it short and playful.
My toddler hates messy play — is that a problem?
Not on its own. Many toddlers are cautious with new textures and warm up slowly. Offer choices, never force, and let them watch you first. If strong distress with everyday textures, sounds or movement is consistent and affects daily life, a friendly developmental check is worth it.
Do I need special toys or equipment?
No. Everyday items — water, dough, rice, fabric, pots, cushions and outdoor surfaces like grass and sand — make wonderful sensory play. The warmth of doing it with you is what matters most.
