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.

"I just feel like encouraging children to behave in intensive repetitive behaviours is not going to be good for their brain."

Firstly, this is just your feeling, it's not based on anything at all that's objective. Secondly, in general parents don't encourage stimming, and ignoring it is not to encourage it. Thirdly, the stimming behaviour originates from the child, it isn't being imposed on their brain, it is part of their make up. People have clearly described how being forced or required to mask their stimming causes them issues, which is the total opposite of your "feeling" about this.

I think you have some specific issues with how the children or adults that you know with autism are being parented or cared for, and you personally find stimming to be something that upsets you. That's my feeling about this.

'This is backed up by several reddit threads'

Yes so proper evidence then?!

Far better to stim than self injury/meltdown etc.

That was literally my first thought when I read this post! “Oh people on a REDDIT thread said this? It must be true!

FWIW my son’s stimming has changed over the years as he’s grown physically and emotionally.

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.

I’m very sure you don’t understand but I think you have good intentions. It’s very difficult to explain over a Mumsnet post. Have you heard of Temple Grandin? She is a professor of science in America, and a very famous autism advocate as she was one of the first individuals to publicly share her experience of autism. There is a film about her life which covers these topics in detail. I think you would find it really interesting.

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.

Ok, but have you considered that chronic anxiety and threat-load increase OCD risk? Or that masking and suppression increase anxiety? And that suppression is more plausibly a risk factor than stimming?

@Muffinmam

GPs don’t diagnose ADHD though?

No, they don't, nor do teachers 'sign it off'. I've not heard professionals use the term 'most severe form of autism' either, what is that @Muffinmam ? Have you reversed it now that your child is verbal and doesn't engage in repetitive behaviour? Communication and repetitive behaviour is part of the diagnostic criteria. Have you cured him autism or reduced him from being the 'most severe form'. If so, have you contacted medical professionals about this? I'm sure there will be many interested in your method used to cure autism.

You don’t stop OCD by telling children to stop pacing. Quite the opposite, if you tell a child with ocd who paces to stop pacing- you make it worse!

Did I say you just tell them to stop and problem solved? No I didn’t. But what you certainly don’t do I tell them and their parents that actually the ocd compulsions are their way of regulating.

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 GP might have wanted information from a teacher to support a referral for assessment, but they didn’t need this to “confirm a diagnosis” - because GPs don’t diagnose ADHD. Why wouldn’t the teacher provide the requested information?

If you found telling him to stim in private so he didn’t “annoy” you so effective that his stims disappeared, he became verbal, and he started playing with others and making friends, with your terribly caring interventions making such a difference that a paediatrician genuinely said they “could not tell he was autistic”…you’ve either found a miracle ‘cure’ (not a thing) and should get in touch with some medical journals, caused intense masking which is likely to cause him a ton of issues as he gets older, or he wasn’t autistic at all in the first place.

Either way, what you’ve described isn’t “the most severe form of autism” is it? (Not that he could have that anyway, as it isn’t a thing).

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.

Thankyou for that. One of the GS is a spinner among other things so I will try calming that or redirecting because I have been wondering as it does seem to make him go some after! I have been letting him spin a bit in the kitchen Also he jumps all over the settee and then spins off rather wildly! No amount of telling him stops him day in day out and it can be dangerous so I'm thinking a distraction technique is needed there similarly?

Don't mean to be hijacking the thread.

Psy193 · 20/02/2026 15:07

I’m a psychologist and specialise in neurodiversity. In 15 years I haven’t come across one person where this was harmful. The harm I have witnessed was from people trying to prevent individuals from engaging with their stim behaviours or try to’teach’ someone to be what others perceive as ‘normal’. So my experience has been the opposite - that stopping it causes harm.

Generally you do see the stimming increase as someone becomes deregulated and it may appear to be becoming aggressive or heavy handed. That is different to the stimming itself being the problem, it’s an indication that someone is trying to self-settle in a situation that isn’t working for them, and id be looking to reflect upon what about the environment (maybe including the people there) would lead to that increased distress and work to change that, rather than try to take someone’s regulatory strategy away.

I’ve never observed a link between stimming and OCD. Rigidity and need for routine and OcD like traits yes, but that links differently to OCD where someone has to engage with compulsions to prevent something bad from happening.

Autistic adults have been diagnosed with PTSD after harmful so-called therapies that rewarded them for suppressing stimming, so no, the science is very clear on this. Children who were left-handed used to be trained to write with their right hand because that was supposedly the norm. That was also harmful.

I agree with this take completely, but no one is arguing that pacing behaviour in zoos is good for the animals surely? Yes sometimes repetitive behaviour is not harmful or even productive, agree.

That’s because animals are not designed to be in zoos and pacing is their only coping mechanism.

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.

There is some degree of overlap between OCD and autism in some people. Autistic stimming helps to regulate the emotional system and are a source of comfort. There is no need to stop autistic people from stimming unless it causes actual harm, which is rare in my experience and can be replaced with something that gives the same feeling of comfort. OCD compulsions are experienced as distressing and can be treated with medication or therapy. It’s that simple.

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

How does pacing or rocking harm you or anyone else? You might not like it, but it’s not harmful to the person doing it. We are not robots.

It is meaningless to 'talk generally' about an extremely complex and very varied set of neurodiverse conditions and behaviours, which affect and manifest in different people in different ways.

Even if you were an expert, which you are not, you wouldn't be in a position to make informed recommendations about the behaviours of neurodiverse people you've never met and examined.

It's hilariously big-headed of you to assume that you know people and their children better than they, and the qualified professionals who treat them, know them. And not only big-headed but downright dangerous to dish out advice based on your assumptions.

Ah, this changes the flavour of the whole thread.

OP, I have autism and OCD. You’re conflating two very different things. I understand your concern about compulsions and anxiety-driven loops, but autistic stimming is a totally different mechanism and serves a very different purpose.

Yes, OCD compulsions do worsen when reinforced, because they are driven by intrusive thoughts and threat reduction. Allowing them strengthens the belief that the compulsion prevents danger.
Autistic stimming doesn’t work like that. It isn’t driven by fear or intrusive thoughts, it doesn’t reinforce a false belief, and it isn’t about neutralising threat. It’s a bottom-up, nervous-system regulation response that discharges sensory or emotional load in real time.
Suppressing non-harmful stimming doesn’t reduce dysregulation, it internalises it. That’s why long-term masking is associated with burnout, anxiety, self-harm and worse outcomes, not better ones.

OCD and autism can absolutely be co-morbid, but that makes functional assessment more important, not blanket “wariness” of repetitive behaviour. The same outward movement can serve completely different roles depending on the underlying mechanism. Treating them as equivalent causes harm.

GiddyAnna · 20/02/2026 15:31

ThatWaryGreenBiscuit · 20/02/2026 14:35

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.

In UK-relevant research and broader meta-analyses, about 10–12% of autistic children/adolescents meet criteria for OCD. That’s not “very common” and stimming doesn’t cause OCD.

I agree with this take completely, but no one is arguing that pacing behaviour in zoos is good for the animals surely? Yes sometimes repetitive behaviour is not harmful or even productive, agree.

But the solution there is to create a better environment for them (which goes all the way up to taking them out of it altogether and releasing them) - not force them to stop doing it by putting them in an even smaller space where they can't pace/turn around/whatever.

You're not talking about making an environment nicer for somebody so they don't need to stim as much in a way that offends your sensibilities, you're just wanting them to stop - which is going to be about as effective as my mother screaming at me to stop biting my nails or somebody in the office putting in a formal complaint because I crack my joints (sometimes intentionally to relieve pain and stiffness)/my joints crack on movement, but going absolutely garrity when the suggestion is that I was moved to a small office of my own.

The thing that is bad for the animal in that situation is not the pacing.

The thing that is bad for them is being confined in a small, stressful space with insufficient mental stimulation.

Stopping the animal pacing doesn't help them - quite the opposite, actually. If you stop them from pacing, it just means the only thing that can relieve their stress is no longer available to them and they suffer a lot more as a result.

What does help them is removing them from the inappropriate enclosure and rehoming them in a more suitable environment. Then their pacing generally either disappears entirely over time, or reduces considerably, because they are no longer under stress.

I thought stimming was just involuntary habits that would be difficult to break. My son bites himself, which is quite upsetting, as a hard lump has now formed on his wrist from the frequency of biting himself. I have showed doctors and specialists, but none of them seem to be concerned at all

The patterns are difficult to break but they often can be. Look into response interruption and redirection.
