If you’ve ever watched your child flap their hands, rock back and forth, spin, hum, or repeat certain sounds or movements over and over again, you’ve probably come across the term “stimming” by now.
And if you’re early on in your journey, I completely understand if it felt confusing at first. Maybe even a little worrying. One of the most common questions parents ask — and I asked it myself — is: “How do I stop this?”
But here’s what I wish someone had told me much sooner:
Stimming is not something that needs to be stopped. It’s something that needs to be understood.
So, what actually is stimming?
“Stimming” is short for self-stimulatory behaviour, and it’s a completely natural way that many autistic people regulate their emotions, their senses, and the world around them.
It looks different for every child. It might be hand flapping, rocking, spinning objects or themselves, repeating words or sounds, bouncing up and down, or tapping and flicking their fingers. And while it might stand out to other people, it serves a very real and very important purpose.
Why do they do it?
Stimming is often your child’s way of coping with big emotions — whether they’re overwhelmed, anxious, excited, or just trying to process the world around them. It helps them feel more in control when things feel anything but.
It can also be their way of managing sensory overload. The world can feel incredibly intense for an autistic child — lights, sounds, textures, smells — things that you and I barely notice can feel absolutely overwhelming to them. Stimming can help block some of that out, or at least make it more bearable.
But — and this is the bit I really want you to hold onto — not all stimming is about distress. Sometimes they’re doing it because they’re happy. Because they’re excited. Because life in that moment is just really, really good.
And that’s exactly what it looks like in our house.
A wee glimpse into our world
Matthew jumps. When I say jumps, I mean really jumps. Full-on, Tigger-style, bouncing off the walls jumping. He has done it since he was about two years old, and it happens whenever he’s excited about something.
Sometimes I’ll be sitting in the living room and I’ll suddenly hear it starting upstairs — this rhythmic, enthusiastic bouncing — and I just know. Something brilliant has happened. Something has made his day. And he literally cannot contain it.
As he’s gotten older, those jumps have gotten bigger. And louder. The living room light actually starts to shake now when he really gets going. I’m honestly not joking when I say I have a very genuine fear that one day he is going to come straight through my ceiling! 😂
But here’s the thing — I would never, ever stop him.
Because that jumping? That is pure, unfiltered joy. That is my boy expressing happiness in the most natural way he knows how. He’s not doing it to be disruptive. He’s not doing it for attention. He’s doing it because he literally cannot keep that excitement inside his body, and this is how it comes out.
Why on earth would I ever want to take that away from him?
Why trying to stop stimming can actually do more harm than good
I completely understand why parents worry about it — especially when you’re thinking about how your child might be perceived by others. But trying to suppress stimming can cause real damage.
When we tell a child to stop stimming, we’re essentially taking away the one tool they have to self-soothe. We risk increasing their anxiety and distress. We might accidentally push them towards coping mechanisms that are far less safe. And worst of all, we’re sending them the message that the way they naturally cope with the world is somehow wrong.
Think about it this way — imagine someone telling you that you’re not allowed to tap your foot when you’re nervous, or take a deep breath when you’re stressed, or pace around the room when you’re trying to think something through. That’s what it can feel like for an autistic child when their stimming is shut down.
But what if the stimming is causing harm?
Most of the time, stimming is completely safe — and it should be supported, not stopped. But there are situations where you might need to gently step in. If the behaviour is physically hurting your child, if it’s creating a genuinely unsafe situation, or if it’s significantly getting in the way of daily life, then it makes sense to look at alternatives.
But — and this is really important — the goal is never to stop the stimming. The goal is to redirect it to something safer. Swapping head banging for squeezing a sensory toy. Replacing biting with chewable jewellery. Giving them a movement break instead of just shutting the behaviour down. You’re not taking away their coping mechanism — you’re finding them a better version of it.
How can you support your child?
The most powerful thing you can do is simply accept them. I know that sounds almost too simple, but honestly — acceptance is everything. Let them stim. Give them the space to do it without judgement. Notice when it happens and what seems to trigger it, because that will tell you so much about how they’re feeling and what they need.
And if the people around you — family members, teachers, friends — don’t understand it, use your voice. Explain it. Because the more people understand stimming, the safer and more accepted our kids will feel in the world.
A wee reminder before I go
You are not doing anything wrong if your child stims. And your child is absolutely not doing anything wrong either.
Stimming is not a problem to be fixed. It’s communication. It’s regulation. It’s self-expression. And when we shift our thinking from “how do I stop this?” to “what is my child telling me right now?” — everything changes.
Your child doesn’t need to change who they are to fit into this world.
Sometimes the world just needs to catch up and understand them a little better.
And that understanding? It starts with us.
P.S. — If you’re ever round at mine and the ceiling light starts swinging, don’t panic. That’s just Matthew. He’s absolutely fine. He’s just very, very happy. 😄
