Why can changes in routines be difficult for some children with autism spectrum disorder?

For children with autism spectrum disorder (ASD), the preference for consistency is a core characteristic of the condition. This manifests as an inflexible adherence to routines and a preoccupation with specific interests or activities.12

When these established patterns, schedules, or familiar environments are disrupted, it can be distressing for the child, often resulting in agitation or tantrums. This difficulty with change is closely linked to the broader category of atypical behaviors, which are typically restricted and repetitive in nature. Because individuals with ASD often rely on these predictable structures to navigate their daily lives, any deviation can feel overwhelming or destabilizing.21
