Interpret thresholds against the developmental slope and functional impact across ICF Activity & Participation (d3) domains, screen hearing in parallel, and refer promptly for combined receptive-expressive delay or any regression rather than adopting watchful waiting.","answer_md":"*Communication unfolds along a predictable trajectory — and knowing the inflection points lets a clinician act decisively rather than reflexively reassure.*\n\n## In short\nConcern is warranted when a child misses a communication milestone with a clear margin, shows **no babble or gesture by 12 months, no single words by 16 months, or no two-word phrases by 24 months** — and especially when any skill regresses at any age. Combine red-flag thresholds with the trajectory and functional impact across ICF Activity & Participation (d3) domains. Persistent receptive-expressive gaps, loss of acquired language, or poor social-communicative reciprocity all warrant prompt referral for structured assessment rather than watchful waiting.\n\n## Red flags by milestone\nUse age-anchored thresholds alongside the slope of development, not a single data point:\n\n- **By 9 months** — limited reciprocal vocalisation, no response to name emerging, absent shared gaze.\n- **By 12 months** — no canonical babble, no pointing, showing or waving; no response to name.\n- **By 16 months** — no single meaningful words.\n- **By 18–24 months** — fewer than expected words, no functional two-word combinations by 24 months, reliance on echolalia without communicative intent.\n- **Any age** — **regression or loss of previously acquired words or social skills is a red flag at any point** and warrants prompt evaluation.\n- **Cross-cutting** — poor comprehension relative to peers, limited joint attention, reduced gesture repertoire, or unintelligible speech beyond developmental expectation.\n\nWeigh receptive and expressive language separately; isolated expressive delay carries a different prognosis from combined receptive-expressive involvement. Always screen hearing first — undetected hearing loss is the most common reversible contributor.\n\n## When to refer\nRefer when thresholds are crossed with a meaningful margin, when there is any regression, when parental concern persists despite apparent milestone attainment, or when communication difficulty constrains participation in play, learning and family life (ICF d3). Do not adopt a wait-and-see stance for regression or for combined receptive-expressive delay — early structured assessment and intervention improve trajectories.
