One slow area often catches up; a pattern across several is the real flag. Worry is a reason to check, not a diagnosis.","answer_md":"*If your little one seems to be taking their own time across many areas at once, the worry is real — and checking is the kindest, most hopeful next step.*\n\n## In short\n[Global Developmental Delay](/global-developmental-delay) (GDD) means a child under five is significantly behind in **two or more** areas of development at once — such as movement, speech, understanding, social skills or daily self-help — rather than just one. At 18–24 months, it's worth a check (not a panic) if your child is **not yet walking, has very few or no words, isn't pointing or sharing interest, doesn't follow a simple instruction, or has lost skills they once had**. One slow area is common and often catches up. A *pattern* of delay across several areas is the real flag — and a reason to assess, not a diagnosis in itself.\n\n## What to watch by 18–24 months\n- **Movement** — not walking by 18 months, very unsteady, or floppy/stiff muscle tone\n- **Communication** — fewer than ~6–10 words, not pointing, not responding to their name\n- **Understanding** — can't follow \"give me the ball\" or point to a body part\n- **Play & social** — little pretend play, limited eye contact or shared smiles\n- **Any loss** of words, skills or eye contact previously present — check promptly\n\n## The science, briefly\nWHO ICD-11 reserves the term Global Developmental Delay for under-fives precisely because young brains are still unfolding — many children simply need time, and some need support. Frameworks like the CDC's milestone checklists and India's RBSK 4-Ds screening exist so concerns are caught early, when the developing brain is most responsive. Identified early, outcomes improve markedly; the goal is always support, never a label.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under a qualified clinician — never from an online form. Our clinician measures your child against their *own* [AbilityScore baseline](/ask/what-is-the-abilityscore-and-how-is-it-calculated), looks for causes, and builds a plan through [early intervention](/special-education) — drawing on 25 million+ therapy sessions across 70+ centres.\n\n## Trusted sources\nWHO ICD-11; CDC Learn the Signs, Act Early; Indian Academy of Pediatrics; AAP (HealthyChildren.org); RBSK developmental screening.\n\n**Next step —** The kindest thing to do with worry is check.
