Refer most urgently on any skill regression, no babble or gesture by 12 months, no single words by 16 months, or no two-word phrases by 24 months — full ICD-11 criteria are not required for referral.","answer_md":"*A child rarely arrives with a diagnosis — they arrive with a pattern the attentive paediatrician is first to notice. Early recognition of autism-spectrum indicators is what converts a routine visit into a timely referral.*\n\n## In short\nWatch for persistent social-communication differences and restricted, repetitive behaviours that span settings and are not better explained by hearing loss or global developmental delay. Act most urgently on any loss of acquired skills, no babble or gesture by 12 months, no single words by 16 months, or no two-word phrases by 24 months. A child need not meet full [ICD-11 6A02](/autism) criteria to warrant onward assessment.\n\n## Early indicators to watch for\n**Social communication**\n- Reduced back-and-forth smiling or joyful, shared expressions by 6 months\n- Limited or absent response to name by 12 months\n- Reduced eye contact; little pointing, showing or following a point to share interest\n- Delayed or atypical language — unusual prosody, echolalia, scripting, or loss of words\n- Limited imitation and reduced spontaneous pretend play by 18–24 months\n\n**Restricted, repetitive behaviour and interests**\n- Repetitive motor mannerisms — hand-flapping, spinning, toe-walking, lining objects\n- Insistence on sameness; marked distress at small changes in routine\n- Narrow, intense interests; atypical sensory responses to sound, texture, or light\n\n**Always act on**\n- Any regression — loss of previously acquired words, babble or social engagement, at any age\n- Persistent parental concern about how the child relates or communicates; parent report is a sensitive early indicator\n\n## When to refer\n\"Wait and see\" is not appropriate once these signs persist across home and clinic. Refer for multidisciplinary developmental assessment, and arrange a hearing check in parallel to exclude sensory contributors. Where concern coexists with feeding, sleep or motor red flags, escalate to a same-week referral. Initiating [autism therapy](/autism-therapy) need not wait for a confirmed label — early engagement supports the family while formal assessment is arranged.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional. The [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) is a clinician-administered structured assessment that gives an objective, multi-domain baseline to complement your clinical impression and to track change once therapy begins — it supports, and never replaces, your judgment. Pinnacle Blooms Network spans 70+ centres across 4 states with 700+ therapists, supporting the referral pathway from first concern through structured [autism therapy](/autism-therapy).\n\n## Trusted sources\nAligned with WHO ICD-11 (6A02 Autism spectrum disorder), the CDC \"Learn the Signs. Act Early.\" milestones, the Indian Academy of Pediatrics, the American Academy of Pediatrics, NICE CG128 on autism recognition, and NIMHANS clinical resources.\n\n**Next step —** to refer a child or set up a clinical referral partnership with your practice, reach the Pinnacle clinical team on WhatsApp: +91 91001 81181.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-early-indicators-of-autism-spectrum-should-a-paediatrician-watch-for","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-early-indicators-of-autism-spectrum-should-a-paediatrician-watch-for","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-early-indicators-of-autism-spectrum-should-a-paediatrician-watch-for-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Autism Early Signs: Paediatric Referral Guide","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"High-yield 10-minute consult check: response to name, pointing to share interest, and pretend play.
