The paediatrician who reads that pattern early changes the trajectory.*\n\n## In short\nWatch for delay that is **global** — across language, fine and gross motor, social and adaptive domains — rather than isolated to one area. Persistent failure to meet milestones across two or more domains, slow rate of skill acquisition, or parental concern about overall development warrants developmental assessment. A young child need not meet full [ICD-11 6A00](/id) criteria to justify onward referral; \"global developmental delay\" is the working term under 5 years, with disorders of intellectual development confirmed once standardised cognitive and adaptive assessment is reliable.\n\n## Early indicators across domains\n**Language & cognition**\n- Limited babble or no single words by 16–18 months; no two-word phrases by 24 months\n- Slow vocabulary growth and difficulty following simple instructions\n- Reduced curiosity, exploratory or pretend play relative to peers\n\n**Motor**\n- Persistent hypotonia or poor head control in infancy\n- Late sitting (>9 months), late independent walking (>18 months)\n- Delayed fine-motor milestones — grasp, transfer, pincer, scribble\n\n**Adaptive & social**\n- Delay in self-feeding, dressing and toileting beyond expected age\n- Limited social referencing and reciprocal interaction\n\n**Always act on**\n- Any developmental regression at any age — escalate promptly\n- Delay across multiple domains plus dysmorphism, micro/macrocephaly, or perinatal risk factors — these merit aetiological work-up and audiology/vision checks in parallel\n\n## When to refer\n\"Wait and see\" is inappropriate when delay spans domains or the gap widens over serial visits. Refer for multidisciplinary developmental assessment, and arrange hearing and vision screening alongside. Early enrolment in [early intervention](/early-intervention-therapy) and [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) supports developmental gains while formal cognitive and adaptive testing matures.\n\n## The Pinnacle way\nPinnacle Blooms Network supports your referral pathway with structured, multi-domain developmental profiling. The [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) is a clinician-administered structured assessment giving an objective baseline that complements your clinical impression and tracks change once therapy begins. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never the output of a screen alone. Backed by 2.5 billion+ data points, 25 million+ therapy sessions and 700+ therapists across 70+ centres in 4 states.\n\n## Trusted sources\nAligned with WHO ICD-11 (6A00 Disorders of intellectual development), CDC \"Learn the Signs.
