TL;DR: Children with autism spectrum disorder may show repeated behaviors, strong interests, sensory sensitivities, or a strong need for routine. These patterns can look different from child to child, and the level of support needed may change as a child grows.
Understanding Behavior Patterns in Autism Spectrum Disorder
Autism spectrum disorder can affect how a child communicates, plays, reacts to the world, and manages daily routines. One of the common signs of autism is the presence of repeated behaviors, strong interests, or difficulty adjusting to change.
These behavior patterns are not the same for every child. Some children may show obvious signs early in life, while others may have milder patterns that become clearer as social and daily expectations increase.
