One quirk is normal; a pattern across settings is worth a play-based occupational therapy check — only a clinician can assess.","answer_md":"*Every toddler explores the world through touch, sound and movement — but for some, the volume of those sensations feels turned all the way up, or all the way down. Noticing the pattern early is a gift, not a worry.*\n\n## In short\nBetween 18 and 24 months, [Sensory Processing Differences](/sensory-processing) show as a consistent pattern of over- or under-responding to everyday sensations — covering ears at ordinary sounds, big distress at certain clothing or food textures, or seeming not to notice bumps and falls. These are differences in how the nervous system takes in and organises information, not naughtiness or stubbornness. A single quirk is normal toddler life; it is the *pattern across days and settings* that is worth a friendly check.\n\n## Signs worth watching at 18–24 months\n**Over-responsive (sensations feel too much)**\n- Covers ears or melts down at everyday sounds — mixers, hand-dryers, vacuum cleaners\n- Strong distress at clothing tags, seams, socks, haircuts, nail-cutting or teeth-brushing\n- Refuses messy play — sand, paint, food on hands — or gags at certain textures\n- Dislikes being held, cuddled or having face washed\n\n**Under-responsive (sensations don't register enough)**\n- Seems not to notice falls, bumps or scrapes that would upset most toddlers\n- Slow to respond to name even when hearing is fine\n- Very high pain threshold; unusually quiet and passive\n\n**Sensory-seeking (craves more input)**\n- Constant spinning, crashing, jumping or rough play\n- Mouths or chews non-food objects well beyond the usual age\n- Loves deep pressure — tight hugs, being squashed under cushions\n\n## The science, simply\nSensory processing is how the brain receives signals from the body and the world and turns them into a calm, organised response. When that filtering develops differently, a child can be flooded or under-fed by ordinary input — affecting sleep, feeding, play and how they settle. Differences often overlap with speech, motor or attention development, which is why a broad developmental view matters. Occupational therapists assess and support sensory development using play-based, evidence-informed approaches.\n\n## The Pinnacle way\nPinnacle Blooms Network supports families through gentle, play-led [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) that builds a child's comfort with everyday sensations at their own pace. A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from an online list. With 4.95 lakh+ families served across 70+ centres, we walk this path with you.\n\n## Trusted sources\nAligned with WHO ICD-11, the CDC \"Learn the Signs.
