What's right now is to watch milestones across movement, communication and social connection, and share any concern with your paediatrician. A persistent delay across several areas warrants a developmental check, not a diagnosis.","answer_md":"*At one year, every baby grows on their own clock — and noticing a gentle lag is the start of support, never a verdict.*\n\n## In short\nAt 12 months, the word \"intellectual disability\" is not something a clinician confirms — it is a label that becomes meaningful only later, usually after the preschool years, once learning and reasoning can be properly assessed. What is appropriate now is to watch developmental milestones across movement, communication and social connection, and to share any concern with your paediatrician. A noticeable, persistent delay across several areas is a reason for a developmental check — not a diagnosis.\n\n## What to gently watch at this age\nThese are early developmental signals, not a checklist for a label. Many healthy babies are simply on a slower-but-typical path.\n\n**Communication & understanding**\n- Little or no babbling (\"bababa\", \"dada\") by around 12 months\n- Doesn't respond to his name or familiar words\n- No simple gestures yet — waving, reaching to be picked up, pointing\n\n**Social connection**\n- Limited eye contact or shared smiles in back-and-forth play\n- Little interest in faces, peek-a-boo or simple games\n\n**Movement & play**\n- Not sitting steadily, or not yet pulling to stand\n- Doesn't reach for or explore toys, or pass objects hand to hand\n- Floppy or very stiff muscle tone\n\n**Always worth a same-week mention to your doctor**\n- Any loss of skills he once had — babble, smiles, sitting\n- Your own persistent worry — a parent's instinct is a sensitive early signal\n\n## Why \"watch and monitor\" is the right stance now\nAt one, a single delay often resolves on its own. What matters is the *pattern over time* across several domains. The kindest, most accurate step is a general developmental check that tracks how your son grows over the coming months — early support for speech, movement or play helps every child thrive, whatever the eventual picture. A formal label like intellectual disability ([ICD-11 6A00](/)) is considered only much later, with proper assessment.\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 or a worry alone.
