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 Are Some Early Signs of Autism?
Communication and Social Interaction
- Limited response to name being called
- Using fewer gestures such as pointing or showing objects to others
- Delays or differences in language development
- Limited back-and-forth social interactions
Play, Behavior, and Sensory Responses
- Playing with toys in repetitive ways or focusing mainly on certain parts of objects
- Repeating certain movements, sounds, or phrases
- Significant difficulties with changes in familiar routines
- Showing very strong or reduced responses to sounds, textures, lights, or other sensory experiences
Developmental Milestones
- Not developing certain communication, play, or social skills expected for their age
- Losing language, social, or other skills previously demonstrated
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.
