A single sign means little; a cluster, or lost skills, warrants a friendly check. A hearing test is sensible first. A clinical AbilityScore and any diagnosis are formed only at a Pinnacle centre under clinician care.","answer_md":"*If your toddler isn't pointing, waving or sharing little glances with you yet, it's natural to wonder — and gently noticing now is one of the kindest things you can do.*\n\n## In short\nBetween 18 and 24 months, the early signs people associate with autism are mostly about **how a child connects and communicates** — sharing attention, gestures, eye contact, responding to their name, and first words. A single difference on its own usually means little; it's the *pattern* over time that matters. If several signs appear together, or your gut says something is different, a friendly developmental check helps you understand what your child needs — many toddlers simply need a little extra support to bloom.\n\n## Signs worth gently noticing\nAround this age, you might watch for a *cluster* of these:\n\n- **Limited shared attention** — rarely pointing to show you something interesting, or not following your point or gaze (\"look at that!\").\n- **Few social gestures** — not waving bye-bye, clapping, shaking head or reaching up to be picked up.\n- **Name response** — often not turning when you call their name, even when hearing is fine.\n- **Eye contact and back-and-forth** — fleeting eye contact, or less of the playful to-and-fro of smiles, sounds and faces.\n- **Communication** — very few or no single words by 18 months, or words/babble that have faded.\n- **Play and interests** — lining up or spinning objects rather than pretend play (feeding a doll, talking on a toy phone); intense focus on one thing.\n- **Sensory and routine** — strong reactions to sounds, textures or lights, repetitive movements (hand-flapping, toe-walking), or big distress at small changes.\n\nNone of these *confirm* autism — many are seen in toddlers who are simply developing at their own pace. What guides a check is the **overall pattern**, especially around social connection and communication.\n\n## When to seek a check\nDon't wait-and-see if you notice several of the above together, if skills your child once had have disappeared, or if your instinct is nudging you. A hearing check is sensible first, since hearing differences can look similar. Reaching out early isn't about labels — it's about giving your toddler the best possible window to grow, when their brain is most adaptable.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online checklist or app. Our team looks gently and holistically at how your child connects, communicates and plays, then builds support that fits your family.
