Autism Symptoms Checklist by Age

Recognizing autism symptoms early can be crucial for getting timely support and creating a supportive environment for development. This Autism Symptoms Checklist by Age is designed to guide parents, caregivers, and educators through common signs of autism in children from infancy to adolescence. By observing specific behaviors and developmental markers, this checklist can help you identify potential indicators of autism at different stages of growth.

How to Use This Checklist

This checklist is divided by age groups, each covering social interaction, communication, behavior, and sensory sensitivities. For each age range:

Observe and Reflect: As you read through each category, think about your child’s behavior and interactions. You don’t need to check every box—autism symptoms can vary significantly.
Document Patterns: Take notes on any consistent patterns or behaviors that stand out. Not all behaviors indicate autism, but observing consistent signs across categories can be helpful.
Use for Guidance, Not Diagnosis: This checklist is not a diagnostic tool. If you notice multiple symptoms that persist over time, consider reaching out to a healthcare professional specializing in autism for a comprehensive assessment.
Review Periodically: Autism symptoms can evolve with age, so revisiting this checklist periodically as your child grows may provide insights into any new or changing behaviors.

This checklist is a supportive resource that helps you observe and understand potential signs of autism as your child develops.

This checklist is intended for informational purposes only and should not be used as a diagnostic tool. Autism is a complex condition, and symptoms may vary widely from person to person. If you suspect that your child or someone you know may have autism, please consult with a qualified healthcare professional for a comprehensive assessment and guidance.
