Because loss of skills is always significant, it warrants a prompt developmental review rather than waiting.","answer_md":"*When a child who once covered her ears at loud sounds suddenly stops noticing them — or a child who loved cuddles now flinches at touch — that shift can be frightening, and it deserves a careful look.*\n\n## In short\nDevelopmental regression means a child loses skills they had already gained — in play, language, movement or social connection — and this often shows up first in **how they respond to the world around them**. A child's sensory development can change in both directions: some children become newly overwhelmed by sounds, lights, textures or touch, while others seem to \"tune out\" and stop responding to things they noticed before. Because a genuine loss of skills is always worth taking seriously, the right next step is a prompt developmental review — not waiting to see if it passes.\n\n## How regression can affect the senses\nSensory development is how a child takes in and makes sense of sound, sight, touch, movement, taste and smell — and uses that information to feel calm, safe and ready to learn. When a child regresses, you may notice changes such as:\n\n- **New over-sensitivity** — distress at noises, lights, clothing labels, food textures or being touched that didn't bother them before.\n- **New under-responsiveness** — not turning to their name, seeming not to hear, or not reacting to pain or temperature as they used to.\n- **Sensory-seeking** — spinning, rocking, mouthing objects, or craving deep pressure and movement more than before.\n- **Loss of regulation** — finding it harder to settle, sleep or recover from busy environments, leading to more meltdowns.\n\nThese sensory shifts often travel alongside changes in eye contact, gestures, words or play. A true regression — a real loss of skills a child had clearly mastered — is different from the normal ups and downs of growing up, and it is always worth a clinician's eyes.\n\n## When to seek help — promptly\nIf your child has genuinely **lost** skills they once had — words, social warmth, play, or steady responses to the world — arrange a developmental review soon rather than adopting a wait-and-watch approach. Loss of skills, especially of language or social engagement, is one of the few developmental signs that calls for prompt assessment so that any underlying cause can be understood and support can begin early.\n\n## The Pinnacle way\nThis is general information, not a diagnosis — Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care, never from an app or online form.
