Stimming, short for self-stimulatory behavior, is a common behavior exhibited by individuals with autism and other developmental disabilities. Stimming refers to repetitive behaviors or movements that an individual engages in for self-regulation or pleasure.

Examples of stimming behaviors include hand-flapping, rocking, spinning, or repeating words or phrases. Stimming behaviors can vary in frequency and intensity and are often used as a way to cope with stress, anxiety, or other intense emotions. While stimming is a normal part of development for many individuals with autism, it can sometimes be misunderstood or misinterpreted by others as inappropriate or disruptive behavior. It is important to recognize that stimming behaviors can serve a purpose for individuals with autism and to support and accommodate these behaviors in a positive and understanding way.
