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.

Op you sound ignorant. Is it possible that many of the Reddit threads have been posted by Americans who had intensive ABA treatment to make them appear more neurotypical. For many kids that has destroyed their mental health. And you need to research autistic burnout often caused by masking.

I agree - Tony Attwood has spoken extensively about this. ABA is marketed as a cure in the USA because therapists can make money from it. Most autism specialists in the UK recognise the harm it causes.

more talking generally

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.

I was only using the term “I’m talking generally” as I was not talking about the persons grandchildren specifically.

do we have to be an expert on something to have an opinion. My opinion is from observing people and children with autism and adhd.

I am not giving out advice, I’m just asking for a discussion which apparently people are unable to have without being rude and completely condescending and making judgments.

👍👍

saying “hmm maybe X advice that is given maybe it could be harmful in these ways” is apparently a completely unreasonable thing to say 🙃

Well you can have an opinion and other people can point out that it’s ill informed and wrong. A discussion isn’t where everyone agrees with you or gives every opinion equal consideration.

TheSoapyFrog · 20/02/2026 15:52

Even if it was harmful, it isn't as harmful as the results of what would happen without been able to stim and regulate oneself.
Trying to train someone out of stimming is veering into ABA territory, which is most definitely harmful.

My son is non verbal and a flapper and a bouncer. Mine is skin picking, so it is quite self destructive as it can cause pain and bleeding. But I've been doing it for at least 25 years, so I don't think it will be easy for me to be "trained" out of it.

It's not so much unreasonable as irrelevant. I know you mean well, but you don't have expertise in this area so why should your thoughts on this trump an expert's opinion?

Luddite26 · 20/02/2026 15:06

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.

Spinning is the particular behaviour that seems to escalate from what I’ve seen in the children close to me. I’ve not seen people say this before so that’s interesting!

My opinion is from working with autistic children and adults for the past 28 years and having postgraduate qualifications in autism and ADHD best practice. I don’t frame myself as an expert. I’m still learning, and people are unique individuals. It doesn’t bother me if people stim. I’m not sure why it bothers you enough to start a thread on the topic.

FatCatPyjamas · 20/02/2026 15:28

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.

Quoting this to highlight it

autistic stims are NOT the same as repetitive OCD behaviours

I guess my question is. Just because it looks harmless, it doesn’t mean it is or there aren’t better ways of navigating things that we haven’t figured out yet.

We are animals and if you have a dog that incessantly chases its tail, no it’s not hurting anyone, but do you think that’s good for the dog mentality? Or do you think it’s better to interrupt and redirect to something less repetitive.

I am particularly wondering if intense repetitive behaviour in itself is not good for the brain if that makes sense.

and just because experts are currently thinking one thing, it doesn’t mean it’s right or they won’t change their minds.

Whilst I’m not an expert I have personal experience myself and my husband and family members children so I am not ignorant of neurodivergence.

My step son is Autistic aged 30 and has a first class degree from a top university. I’m sure if he could stop stimming he would, he is embarrassed by it but he can’t control it. He might be able to mask for so long but realistic then he has to. He tics, stimms and jerks - he isn’t in control. Out in public he tries hard not to but he will rock, head slap etc after a while.

Your post shows total ignorance of ND. I am autistic but I hide my stress relievers and you would not know when you are talking to me that I’m counting right angles etc but I will be able to repeat back to you word for word word what you have said even up to 24-48 hours later and I mean word for word.

If you’d read my post you’d see where I specifically said that obviously not all stimming is negative. If it’s potentially hurting the children I love them I will speak about it. How is it harmful to speak about whether stimming May be harming mental health. What is harmful is any discourse that doesn’t fit exactly what the current popular opinion on autism or adhd, even if it’s not actually helping the children that are struggling.

may consider not being so rude to someone you know nothing about

Have you considered that current opinion might be popular because it is evidence-based and therefore more valid than a thought or feeling?

I'm not really sure your point. A lot of occupational therapy with autistic people is about replacing unhelpful or not socially acceptable stims with ones a person can include as part of regular life.

Eg: my son would regularly bang the table bangbangbangbang. His OT in school worked with him to change it to tapping his leg (less disruptive), then to tapping a little fidget thing he can carry round with him. They've done this with a lot of different stims. Totally normal.

Stimming = ok
Socially unacceptable stims = lots of therapy available to swap them for more social ones.

Yep the brain's plastic to a certain extent.

But the literal reason we have a diagnosis of autism that exists is a recognition that some brains can't be trained in the same way. That's why it's a LEARNING disability.

Because if it were possible, we could train people not to be autistic. And we can't.

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.

Wow, you have cured autism!

Better let the professionals know.

MyKindHiker · 20/02/2026 16:12

FuzzyWolf · 20/02/2026 14:16

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.

So you think @Muffinmam is lying and did not in fact cure her severely autistic child through the medium of firm boundaries? 🤔

I’m simply wondering if SOME stimming behaviour is not good for a person’s mental health due to it being very intense repetitive behaviour (eg pacing, rocking, spinning…) that may create a pathway to MORE intense activity and less regulation and more overstimulation in a child especially (I have seen this happen which is what got me researching and seeing the advice to let them carry on)

im in no way saying all stimming behaviour does this and obviously it will depend on the person

I am really curious about your story. I tend to think people don't go online to just post made up stuff (because... why) but this honestly does sound very very made up, not least that the language you use implies a very limited experience of the diagnostic process or language we typically use about autism. But maybe you're from a place where that's the process and the language. If it were the case and you are being honest I'd be really interested in your experience teaching a non-verbal child to be verbal and getting them to change all of their behaviors. I'd also be really interested in your child's perspective.

And your definition of 'severe' autism as the kids I know who are 'severely' autistic (even if we don't use that term in the UK) are still in nappies in their 20s and absolutely cannot be taught to talk or not flap or anything else.

Or maybe you're a Russian robot, I gather a lot are on here.

Well there isn't much to argue about on that. The therapeutic community is already in agreement with you. Which is why there are millions of therapies aimed at replacing harmful or unhelpful stims with helpful ones. It's literally a whole branch of occupational therapy. It's been my son's focus in OT for years - successfully I'd add.
