Definition
Stereotypy is the clinical term for repetitive movements, sounds, or actions, such as hand-flapping, rocking, or repeating phrases. In everyday and community language, most of this is simply called stimming.
Why It Matters
The word appears throughout medical and educational paperwork, so families benefit from knowing it usually refers to stimming. Reframing it from a symptom to a self-regulation tool changes whether it is supported or suppressed.
Common Misconception
Stereotypy is not inherently harmful or meaningless, and it rarely needs to be eliminated. Suppressing it removes a regulation strategy and is linked to increased distress; the goal is safety, not stillness.
