What is one of the first signs of autism spectrum disorder in children?

Avoiding eye contact is recognized as one of the first signs of autism spectrum disorder (ASD) in children. Children with ASD may have difficulty engaging socially, which is evident early on through their reluctance or inability to make eye contact. This can be a significant indicator of the challenges they may face in social interactions and communication as they grow.

Increased physical activity, excessive talking, and strong attachment to toys do not specifically characterize the early signs of ASD. While children with autism may display varied behaviors, such as hyperactivity or focused interests, these traits can manifest differently and are not exclusive indicators of autism. The lack of eye contact is more closely associated with the social communication difficulties that define ASD, making it a crucial early sign for identification and intervention.
