To think that stimming (especially destructive or very intense) is potentially not helpful or even harmful in the long run?

I’ve seen a lot of advice that stimming behaviour in individuals with autism or adhd is helpful and regulating, however instinctively this feels wrong to me.

The brain is plastic and can be trained to expect certain things and I feel like that failing to redirect ourselves or our children to more healthy ways of experiencing overwhelm is only making stimming worse. And possibly the overwhelm worse in the long term.

this is backed up by several Reddit threads, where people said allowing themselves to stim, made the stimming worse, but the mainstream opinion is to let the stimming happen.

Instead of teaching life skills and how to get through day in an off ten overstimulating world, is it healthier to rely on potentially problematic behaviour as a way of getting by.

I know I’m probably kicking a hornets nest here, but this is not to suggest that ALL stimming is bad or anything like that. We don’t know everything about the brain or our behaviour, so I think it’s good to discuss things so we can work towards helping everyone rub along together. I hope this makes sense.

Could you give some concrete example of what you consider non-helpful stimming, and why you think it intensely repetitive behaviour might cause escalation to harmful acts?

BauhausOfEliott · 20/02/2026 14:04

Maybe you could just let people decide for themselves based on the innumerable different nuances and circumstances that will apply to their own child (or themselves) rather than taking it upon yourself to inform them what you have decided based on ‘several Reddit threads’.

Some points as I don’t know how to reply:

If the activity is genuinely non helpful then of course I don’t have a problem with it, why would I?

I am questioning whether certain stimming behaviour that is often seen as harmless or beneficial to the person is actually harmful. For example intensely repetitive behaviour could actually be feeding into a loop of behaviour that will escalate into more harmful behaviour or ocd type behaviour who’s definitely not healthy to a person. Especially as many individuals who stim may also have ocd struggles or tendencies.

I only mentioned Reddit as it’s difficult to find open discussions on this without it spiralling into defensiveness. a this thread was discussing what I was thinking.

No I would never tell a child off for stimming or make them out to be a bad person.

I don’t see why it’s not possible to discuss the best methods for helping autistic or adhd people when you have them in your life. Not every piece of professional advice is solid so just because the research has a conclusion right now doesn’t mean it’s right or right for everyone.

I can only speak for ADHD stimming, but who cares if you repeat song lyrics, twiddle hair/fingers or do swimmers feet, in the comfort of your own home. You aren’t hurting anyone, if OP is talking about stimming being something to be ashamed of in public, I can’t see how that would be helpful. It doesn’t bother me if someone is regulating in a way I don’t understand.

audiehd · 20/02/2026 14:08

Well, typically if I'm visibly stimming it's either that or slowly build towards a meltdown. Often in public. I'd rather not be screaming, crying and hitting myself at the bus stop, so a little rocking back and forth as I stand and wait seems like a pretty good trade-off personally. Since I was diagnosed in my teens and stopped suppressing my urge to stim, I've barely had any meltdowns at all when I used to melt down regularly. I can safely say that stimming has massively improved my wellbeing by preventing such frequent meltdowns, which left me exhausted and ashamed.

In general, I barely notice my own stimming. It's mostly things like knitting (a repetitive hand motion), chewing gum, jiggling my knee, or humming to help me focus (if I'm alone). It's just a background element of my life. Obviously self-injurious stims are harmful both long-term and short-term and should always be redirected where possible, but hand flapping or pacing can be wonderfully regulating. If I suppressed my stims the way I used to, my ability to go out and about, travel, work, and socialise would be vastly curtailed.

geminicancerean · 20/02/2026 14:08

Who decides what is ‘helpful stimming’ or ‘unhelpful stimming’? Is it you, OP? You might not enjoy the sound of my child bouncing up and down the hallway hundreds of times a day but nobody in our house cares,

Do you realise that everyone 'stims' to some extent - things like hair twirling whilst on the phone, whistling/humming when happy or pen tapping in meetings is also stimming. Try to go for the next 24hrs only sitting perfectly upright in the 'correct' posture on your chair, being totally still when standing and making no extraneous movements with your limbs, head or face whatsoever (like a robot) and see how unnatural it feels and how much extra processing effort it takes up!

Edited

This is a really interesting point. 3 out of 4 of my girls stim. Even still at 10. Only when excited (twist hands at wrist furiously) or playing. None of them have any additional needs or diagnosis. I myself constantly twirl hair all day every day and have done all my life.

I have often wondered for my second daughter if it was learned behaviour as my first daughter did this and they were very close in age. It's something I've always wondered. My third daughter flaps but at 7 has pretty much grown out of it.

smallglassbottle · 20/02/2026 14:15

Self injurious stims can produce endorphins, which can relieve distress and calm the individual.

Are you secretly just concerned with the embarrassing, attention drawing ones op?

FuzzyWolf · 20/02/2026 14:16

Muffinmam · 20/02/2026 13:51

I completely agree with you.

I have a child with the most severe form of autism, GDD and suspected ADHD (GP wanted a sign off from a teacher to confirm his diagnosis).

When my child was a toddler he would suddenly rock so violently that I would get injured. I put a stop to that along with the flappy hands, vocal stimming and walking on tippy toes.

I also found that when he was encouraged to do things like spinning (by his speech therapist) he would go absolutely feral. I told her not to do that because he would get himself into a situation where he wouldn’t stop. She argued that autistic kids like it. So I sat back and let her deal with him. It didn’t calm his nervous system - it put him into a state where his behaviour continued to escalate until the point he would physically injure himself.

At home he would need more and more to satisfy his sensory needs and would run full force into furniture.

My concern was all of his behaviours were preventing him from making friendships as well as preventing him from interacting with the world. His Paediatrician told me that we need to get him out of his world before the age of 9-10. So that’s what I focused on.

I was so successful in stopping his behaviours that new Paediatricians told me they could not tell he was autistic.

He talks (previously he was non verbal), he’s made friendships and he plays with others.

I absolutely refused to lean in to his behaviours. I told him if he felt it necessary to carry on then he should go up to his room and do in private and that he shouldn’t annoy me.

I support him. I’ve given up my amazing career for him. I refused to be home all day with a kid that was non-verbal, who groaned, moaned, yeeped, rocked, self harmed (he used to hit himself in the head), who flapped his arms like a bird and walked around on his toes.

The way you describe your child does not sound like autism at its most severe (and there is no such thing as the most severe form of autism). Likewise, as a PP said, a GP isn’t involved in an ADHD assessment.

bigkicks · 20/02/2026 14:17

I can no more stop my severely autistic non verbal DS from stimming than I could part the seas. He gets plenty of looks and stares from people like you, you get used to it. It's in every noise, every movement, every second. If he's not hurting himself or anyone else then happy days, he has no sense of where he is in space, bouncing, jumping, stomping wiggling his arms are the way his brain is compensating for that, without it, he has inadequate vestibular input. It's quite clever really, very interesting to research if you wish to educate yourself.
Imagine you're in a car going backwards with a blindfold on, four different songs playing at in your ears at once. That's how he feels if he doesn't stim, in a crude way it's similar to how a blind person's other senses compensate. Why would you want to stop that? Would you prefer his meltdown? It involves headbanging, concussion, biting himself down to the bone, unbelievable screaming, serious violence. I know which I prefer.
There can be harmful or antisocial stims, which require redirection, this requires work, and effort I suspect you have no idea about. I won't go into them as I expect that will reinforce your negative stereotype, but please understand it's not as simple as just stopping them, especially if coinciding with a learning disability.

  • Autistic stimming stimming does not cause OCD
  • Allowing stimming does not increase OCD
  • OCD is driven by intrusive thoughts and threat reduction, not sensory regulation.

Sure, they can be co-morbid or exist in isolation, and a clinician would need to assess what the route cause of the repetive movement is, and what purpose it serves, before decreeing it "harmless" or "problematic".

Luddite26 · 20/02/2026 14:23

I have met a couple of parents whose children have autism and I have wondered when they have asked them to calm down why they are stopping them stimming and this has been in their own homes. I don't understand why they ask them to calm down. And both these parents are highly educated. Other parents I have been in contact just seen it as part of autism. So I have privately questioned whether they are right to say calm down.
Personally I feel better to be natural and let a person's nervous system function in its own way. I feel blocking things makes a pipe burst further down the line.
I'd never stop anyone stimming to fit in with a perception of conformity unless they were going to hit someone or something in the vicinity like in a shop.
People obviously stim for a reason. I would personally compare stopping stimming similar to when people used to try and get left handed people to write with their right hand.

These would be examples of stimming behaviour that I have witnessed from children close to me. Pacing, spinning, loud noises, jumping, rocking, head shaking. Instead of calming or grounding it seems to create a negative cycle that leads to them doing the behaviour more often or more loudly, violently etc if it’s not interrupted and replaced with a different behaviour.

I do not think these children just not get over it and their struggles should be dismissed. But I don’t think this behaviour is helpful and instead seems to be leading to more harmful behaviour and I worry about the potential harm letting them behave in such intense repetition is for their mental health.

@ThatWaryGreenBiscuit

You seem to be saying that you are against destructive behaviour and self harm, which I feel we would all agree upon but you go on to say that it’s the repetition that isn’t good, and give the example of a dog chasing its tail.

I know that we don’t fully understand the brain. I think that only the smallest percentage of people in this world consistently do everything in their power to maximise their mind and body. The rest of us often choose to not stop doing something, because it simply makes us feel better. That is the most normal approach.

So when it comes to people with ASD, why should we expect them to fight against something that is helpful to them in favour of a possible undefined benefit in the long term. No one else does this to such an extreme.
Would it be better if I did more exercise? Probably yes, but because I’m a human and not a robot, I don’t feel the need to be programmed into the best possible model of myself. I don’t need an upgrade!

Of course not everyone needs to do everything all the time, but there’s a difference between saying a potentially harmful behaviour is actually good for someone and saying, this behaviour isn’t probably good for me, but I don’t have the headspace to deal with it right now.

If stimming helps soothe someone whose nervous system is heightened why is that a problem? I have two autistic grandchildren. One stims by jumping up and down and arm flapping and the other doesn’t but masks very effectively. She tends to explode or have a meltdown so they both cope with a disregulated nervous system in different ways. So long as they don’t inflict harm on themselves or others why worry?

Only because I am questioning if it IS harmless. Maybe it is maybe it isn’t, I just feel like encouraging children to behave in intensive repetitive behaviours is not going to be good for their brain. BUT obviously it heavily depends on the person and how the behaviour is being displayed. Ie is it escalating in intensity or occurrence or leading to anxiety or in itself masking something that could be fixed.

not saying this is the case with you necessarily, more talking generally

Do you have any evidence these things create a negative cycle? At the moment this just seems like anecdote rather than research

My DS stims a LOT by bouncing on his heels and uttering a little groany noise. It’s how we know he's content. If he’s unwell or unhappy the stimming stops and we are always relieved her hear him resume his bouncing again. Politely, OP, you know very little about this and probably need to have a lot more experience of being around neurodiverse individuals before you make sweeping conclusions about their natural behaviours.

Yes, my adult son has his happy noise. When he stops making it it's the first sign I have that he is feeling unwell or anxious.

SENDmam · 20/02/2026 14:34

The OTs that i spoke to in regards what to say to parents said that the only one they say to reduce in children is spinning as it stimulates rather than regulates and to try to redirect towards rocking or have it as a very controlled spin. Other than that allow the child to do what they need to do to regulate their sensory systems.

ocd Is very common with autism so I’d say it’s enough to be wary of the potential negative side to certain stimming behaviour, especially when it’s children.

Suppressing non-harmful autistic regulation in favour of cognitive “skills” doesn’t eliminate dysregulation, it postpones and internalises it. The long-term risks of that are VERY well documented.

You can teach, emotional literacy, planning, exits, boundaries, breathing, grounding etc which can be useful, but none of them discharge sensory load the way a stim does in real time. Replacing a reflexive nervous system response with a conscious override is masking, which keeps a nervous system in a state of unresolved stress.
