Stimming is autism terminology for self-stimulatory behavior, or anything that autistic people do to stimulate the senses that they find soothing or enjoyable.
My daughter has a number of stimming behaviors that we see on a daily basis. For example, she often spins in circles reciting the alphabet, or bounces up and down on her heels while counting. When excited, she rocks back and forth rapidly. When sitting down, it looks like she is energetically rowing an invisible boat.
My husband and I very much subscribe to the idea that stimming is not to be discouraged, but rather accepted as part of who our daughter is and even celebrated. Stimming helps her calm down when she is bombarded with too much sensory input. A common misconception about ABA therapy is that the therapists will punish or prevent stimming, but our experience has been that the therapists accept and wait out stimming behaviors. Her therapy team is completely on board with our attitude.
The exception to the rule is when stimming becomes self-harming, which is unfortunately common. In my daughter’s case, she used to bang her head against the wall when she was tired. We did discourage that behavior and it has since naturally stopped. In the past few weeks, a new behavior has emerged. She now smacks herself in the face, usually in the forehead area. She even leans into the hits. I am torn about this, because she doesn’t seem to be causing any viable damage (skin looks normal) and I doubt she is hitting herself hard enough to cause any internal injury. But if I allow this to continue, who knows what it might turn into, plus it’s just disturbing to see your child repeatedly hit themselves. She also has a very high pain tolerance, seeming to not even notice falls and scrapes that would have other toddlers bawling, so I worry she may hurt herself and not notice. I’m going to ask her doctor about this at her next appointment, but it’s a month away.
Kiddo also enjoys makes lines out her toys, like many autistic children. I’m not sure if this counts as stimming but I’m including it here because she made some nice lines this weekend and I thought it was cute. Notice how the boats have been given their own line, and all the airplanes are sorted out in a pile at the back.
