What are the early signs of autism in children?
Early signs of autism can include limited eye contact, not responding to their name by about 12 months, few gestures such as pointing or waving, delayed or unusual speech, little interest in shared play, repetitive movements, strong reactions to sounds or textures, and distress at small changes. One sign alone is not a diagnosis; a pattern that persists needs professional assessment.
What this means in practice
Parents and early years teachers are often the first to notice differences. Early identification matters because early intervention can support communication and learning during a period of rapid development.
Signs to note by age
- By 12 months: little babbling, pointing or response to name.
- By 18 months: few single words, little pretend play, not showing objects to others.
- By 24 months: few two-word phrases, loss of previously learnt words or skills.
- Any age: repetitive play, strong sensory reactions, difficulty with change.
What to do in India
Talk to a paediatrician. RBSK screens children for developmental delays, and District Early Intervention Centres provide assessment and support in many districts.
Talking to families about early signs
Share concerns privately and gently, using specific observations rather than labels. Many parents have already noticed differences and may feel relieved, worried or defensive. Offer practical next steps and keep supporting the child in class whatever the family decides.
Practical next steps
- Record specific observations with dates.
- Use a recognised milestone checklist.
- Share concerns with the family sensitively.
- Encourage referral to a paediatrician or early intervention centre.
What to keep in mind
Do not label a child as autistic. Describe what you see and support the family to seek assessment.
Common follow-up questions
Can autism be diagnosed at 2 years?
Yes, specialists can often make a reliable diagnosis around this age, sometimes earlier.
Does a speech delay mean autism?
Not necessarily. Speech delays have many causes, so an assessment is needed.
