What Is Chinning in Autism? Understanding Self-Stimulatory Behaviors

Priya Anand

PsyD, BCBA

Priya found her way into ABA through developmental psychology, and she's spent the last 13 years focused on the earliest years.

In autism discussions, you may come across the term chinning.” Chinning is a type of self-stimulatory behavior (often called “stimming”) where a person presses or rubs their chin against objects, surfaces, or even people. For individuals with autism, stimming behaviors like chinning serve an important purpose in regulating emotions, managing sensory input, or expressing excitement.


Chinning may look unusual to others, but it is typically a harmless coping strategy. Just like hand-flapping, rocking, or spinning, this repetitive movement can help an autistic child or adult feel calmer in overwhelming environments or more engaged when they are excited.


However, if chinning leads to discomfort, skin irritation, or becomes disruptive, families can work with professionals to explore alternatives. Replacing the behavior with safer sensory activities—such as using fidget toys, applying gentle pressure with pillows, or engaging in structured movement—can help meet the same sensory needs in a supportive way.


At Steady Strides ABA, we understand that stimming is a natural and valuable part of autism. Our approach focuses on respecting these behaviors while teaching safe strategies that help individuals thrive in daily life.
