Act most urgently on loss of acquired skills, persistent language milestone failure, adaptive shortfall, dysmorphism or genetic risk, and parental concern. An intellectual disability label is not assigned in early years; refer on the delay pattern.","answer_md":"*A young child rarely presents with a diagnosis — they present with a gap between expected and observed development that the first clinician notices across several domains.*\n\n## In short\nRefer for assessment when developmental delay is **global** — spanning cognition, language, motor and adaptive skills — rather than isolated, and when milestones lag persistently across settings. Most urgently, act on any loss of acquired skills, failure to meet language milestones, or significant adaptive-function shortfall, alongside parental concern. A formal [intellectual disability](/intellectual-disability) (ICD-11 6A00) label is not assigned in early years; refer on the delay pattern, not on a presumed label.\n\n## Red flags that warrant referral\n**Cognitive / language**\n- No babble by 12 months; no single words by 18 months; no two-word phrases by 24 months\n- Poor receptive understanding — not following simple routines or instructions\n- Limited symbolic or pretend play; slow problem-solving relative to peers\n\n**Motor and adaptive**\n- Persistent gross- or fine-motor delay (late sitting, walking, manipulation)\n- Difficulty acquiring self-help skills — feeding, dressing, toileting — beyond age expectation\n- Delay across **multiple** domains rather than one isolated area\n\n**Always act on**\n- Any regression or loss of previously acquired skills, at any age\n- Dysmorphism, micro-/macrocephaly, or known genetic/perinatal risk\n- Persistent parental concern — a sensitive early indicator\n\n## When to refer\n\"Wait and see\" is inappropriate when delay is global and persistent. The child need not meet full 6A00 criteria — intellectual functioning is unreliable to quantify in very young children, so refer on the developmental pattern for multidisciplinary evaluation, hearing and vision checks, and aetiological work-up. Begin [early intervention](/early-intervention) in parallel; do not defer support pending a formal label.\n\n## The Pinnacle way\nPinnacle Blooms Network supports the referral pathway with structured, multi-domain developmental profiling. The clinician-administered [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) provides an objective baseline that complements your clinical impression and tracks change once intervention begins. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — it supports, never replaces, your judgment, and is not a diagnostic test.\n\n## Trusted sources\nAligned with WHO ICD-11 (6A00 Disorders of intellectual development), CDC \"Learn the Signs.
