Early Signs of Autism in Young Children

Why early awareness helps

The CDC notes that autism can sometimes be detected at 18 months or younger, and that early support can make a meaningful difference in a child's skills and well-being.

Signs the CDC describes

• Not responding to their name by around 9 months
• Few or no gestures, such as waving or pointing, by around 12 months
• Limited shared attention — for example, not looking where you point
• Lining up toys or objects and becoming upset when the order changes
• Repeating words or phrases, or losing skills they previously had
• Unusual reactions to the way things sound, smell, taste, look, or feel

Remember

Children develop at different paces, and having one or two of these signs does not mean a child is autistic. Only a qualified professional can make a diagnosis.

What to do if you're concerned

Track the milestones you notice, write down examples, and share them with your child's doctor. You can ask for a developmental screening. In many countries, early intervention services are available — check what's offered where you live.
