Understanding ADHD Stimming: 10 Common Examples

By Autism Mom · · 3 min read

ADHD brains stim too—and it's not the same as autism stimming. Here's what it looks like and why it happens.

ADHD Stimming Is Real (And It's Different)

As a mom of an autistic child AND someone with ADHD myself, I see stimming from both perspectives. And while there's overlap, ADHD stimming has its own flavor.

ADHD stimming is often about:

Autism stimming tends to be more about sensory regulation and emotional processing.

Both are valid. Both are natural. Neither needs to be "fixed."

Why ADHD Brains Stim

ADHD brains are often understimulated. Weird, right? We seem so "busy" on the outside, but internally, our brains are seeking stimulation constantly.

Stimming provides that missing input. It can help us:

10 Common ADHD Stims

Do any of these sound familiar?

1. Fidgeting with Objects

Constantly playing with pens, stress balls, fidget spinners, jewelry—anything in reach. I'm literally fidgeting with my ring right now.

2. Leg Bouncing

Repeatedly bouncing or shaking a leg while seated. My husband always notices when I'm anxious by how fast my leg is going.

3. Hair Twirling

Twisting or playing with hair, often without even realizing it.

4. Pen Clicking

The sound drives others crazy, but for us it's soothing. Click click click.

5. Pacing

Walking back and forth, especially when thinking or anxious. I do my best brainstorming while pacing.

6. Nail Biting

Chewing on nails or cuticles as a stress response.

7. Foot Tapping

Rhythmic tapping that helps release energy and maintain focus.

8. Humming or Whistling

Making quiet sounds to self-soothe or concentrate.

9. Chewing Gum

Constant chewing helps many ADHD folks focus. I go through packs of gum.

10. Drumming Fingers

Tapping out rhythms on any available surface.

How to Support ADHD Stimming

Create Stim-Friendly Environments Keep fidgets available. Allow movement breaks. Don't shame the bouncing leg.

Use It Strategically Need to focus on a boring task? Give yourself permission to fidget. It actually helps.

Redirect When Necessary If a stim bothers others (like pen clicking in a meeting), find a quieter alternative. Squeezing a stress ball, perhaps.

Understand the Need Stimming isn't a behavioral problem—it's a need. Meet it rather than fight it.

For Parents of ADHD Kids

If your child fidgets constantly, bounces in their chair, or can't sit still—that's their ADHD brain seeking input.

Try:

Fighting the fidget usually backfires. Working with it works better.

Fellow ADHD folks—what's your stim? I want to hear I'm not alone in the pen clicking. 💛
