As a parent, you know your child better than anyone. If something feels different or your gut is telling you that something isn’t quite right, it’s worth paying attention to. Early signs of autism can appear as young as 6–12 months, although many families notice differences between 18 months and 3 years.
Autism is not about what a child can't do. It's about how their brain is wired, and early support helps that brain thrive.
Social Signs
• Limited or no eye contact, especially during play or feeding
• Not smiling back when you smile at them
• Not responding to their name by 9–12 months
• Seeming to prefer being alone rather than being around people
Communication Signs
• No babbling by 12 months
• No single words by 16 months
• No 2-word phrases by 24 months
• Loss of previously acquired language skills (very important red flag)
Behaviour Signs
• Repetitive movements such as rocking, hand-flapping, or spinning
• Intense focus on one object or topic
• Becoming very upset by small changes in routine
• Unusual reactions to sounds, textures, or lights
Spotting signs early doesn't mean a diagnosis is certain. But it does mean you can get your child assessed and start support sooner.
If you notice several of these signs, talk to your pediatrician about a developmental screening or autism assessment.
