Autism Development & Early Childhood

Early Signs of Autism

Children grow and develop differently. Some early signs of autism may be noticeable in how a child communicates, interacts with others, or responds to their environment. Recognizing these differences can help families determine when to seek further guidance.

What Should I Do if I Have Concerns?

Talk to your child’s pediatrician

Share any differences you’ve noticed in your child’s development and ask whether developmental screening or further evaluation is recommended. The American Academy of Pediatrics recommends autism-specific screening at 18 and 24 months, as well as additional screening whenever developmental concerns arise.

Learn about evaluation options

In California, families can contact their local regional center for a no-cost developmental assessment. Regional centers often conduct or arrange autism diagnostic evaluations when needed to determine eligibility for services. Your child’s pediatrician can also help guide you toward an autism diagnostic evaluation, if needed.

Explore available support

If your child has an autism diagnosis or is experiencing developmental challenges, early support can help build communication, play, social, and everyday living skills.
