If your son is behind in two or more areas together, or has lost skills, seek a developmental check. Early support helps now, without waiting for any label.","answer_md":"*A two-year-old shows you the world through play, gestures and first words — and when several of those threads run a little behind, it is worth a gentle, timely look rather than a worry.*\n\n## In short\nAt two, no single sign confirms intellectual disability — and the term is rarely applied this early. What clinicians watch for instead is *global developmental delay*: a child noticeably behind across several areas — talking, understanding, playing, problem-solving and daily skills. If your son is lagging in two or more of these together, a developmental check is the right, calm next step — not a diagnosis.\n\n## Signs worth a closer look at two\nThese are reasons to ask for a check — not labels in themselves. Children develop at different paces, and many who are slow at two catch up beautifully.\n\n**Communication & understanding**\n- Few or no clear words by 24 months, and not yet joining two words together\n- Doesn't follow simple instructions like \"give me the ball\"\n- Limited pointing, showing or sharing with you\n\n**Play & thinking**\n- Little pretend play (feeding a doll, \"talking\" on a toy phone)\n- Doesn't explore toys with curiosity, or plays in very repetitive ways\n- Struggles with simple cause-and-effect toys other children manage\n\n**Everyday & motor skills**\n- Not yet walking steadily, or not feeding himself with a spoon\n- Trouble with simple self-help his peers are picking up\n- Slow to reach several milestones, not just one\n\n**Always act promptly on** any *loss* of skills he once had, or a strong, persistent feeling that several areas are behind together.\n\n## When this becomes meaningful\nA formal diagnosis of [intellectual disability](/) (ICD-11 6A00) generally isn't made in toddlers, because cognition can't be reliably measured this young. The appropriate stance now is **watch, support and monitor**: gather a developmental profile, begin early support where helpful, and re-check over time. Early stimulation and [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) at this age can make a real difference, whatever the eventual picture. Bring it to your paediatrician and a developmental check without delay — early support never has to wait for a label.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online list. Our clinician-administered [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) maps your son's strengths across communication, play, motor and daily-living skills, giving a clear, encouraging baseline to act on and track. Backed by 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, support is built around what your child *can* do next.\n\n## Trusted sources\nAligned with WHO ICD-11 (6A00, disorders of intellectual development), the CDC's \"Learn the Signs. Act Early.\" milestone guidance, the Indian Academy of Pediatrics, and the American Academy of Pediatrics' HealthyChildren guidance on developmental monitoring.\n\n**Next step —** book a gentle
