Walk into any toy shop now and you'll find a shelf marked “sensory toys”. Textured balls, bubble tubes, chew necklaces, swings and squishy toys in every shape and colour you can imagine. It's one of the fastest growing niches of the toy world, and one of the hardest to shop for.
Children are drawn to them for many reasons. It’s satisfying to squish something, let rice run through your fingers or spin a fidget spinner. It's curiosity and control. Press, and it pops. Squeeze, and it gives. Do it again, and it happens again, exactly the same way, which is a rare and rather lovely feeling when you’re small. Sensory toys take what children do anyway and give them something made for it. Hence why they suit babies and big kids perfectly.
So what are they, what do they do, and what you need to know before buying one?
What is a sensory toy?
A 'sensory toy' is classed as any toy made to stimulate one or more of the eight senses: the five traditional ones you learned at school (touch, sight, sound, smell and taste) plus three you probably didn't (balance & movement, body awareness and interoception).
It gives children some predictable sensory input they can control which helps them discover, focus, learn and settle.
This can be through something as simple as a textured ball, pop it, a chew necklace, a tray of dried rice or a garden swing. But so can a lot of what's already in your home such as bubble wrap, fabrics, sand or pasta bins.
But what about balance and movement, which lives in your inner ear? This is known as the vestibular system. It tells you which way up you are, this is how you climb the stairs without watching your feet.
Body awareness is the one that tells you where your arms and legs are without looking. It's how you do up a zip behind your back, or cross a dark room without walking into the furniture.
The eighth gets left out but it's worth knowing: interoception.
This is your body's internal sensory system that lets you feel, notice and understand signals coming from inside your organs. Things like hunger, heart racing, full bladder, tiredness, etc. Children who find those signals hard to read often can't explain why they feel poorly. No toy fixes this, but understanding it changes how you respond.
Sensory play starts long before school
Babies arrive knowing nothing about the world, and they only have one way of finding out. They have to touch it, mouth it, shake it, and drop it!
That's why everything goes in the mouth first. For the first few months your baby's lips and tongue are far more sensitive than the hands, so mouthing really is the quickest way a baby has to gather information.
To take this further, a newborn doesn't yet know their own hands belong to them. Somewhere around two or three months most babies find their fingers and simply stare, turning them over like they've discovered something remarkable, which of course they have. That's sensory play doing its job.
Even the annoying habits are learning! A baby dropping the spoon from the high chair for the fortieth time isn't testing your patience, they're testing whether it falls every single time.
A good baby toy doesn't have to be expensive or grand. In fact, the big bulky toys that light up, sing and flash are usually the ones that get played with least from my experience. My one year old has endless toys but her favourite? The TV remote, she’s completely obsessed with it!
Honestly, it makes sense when you look at what a remote actually offers her: a nice weight in the hand, buttons that click, and something happening across the room every time she presses one. That's the recipe. Something soft, something firm, something with a bit of weight, and something that responds when they touch it.
Household items so often win, your kitchen will be full of them!
Which sensory toy should I choose?
Start with your child, not the product would be my advice. The question isn’t “which sensory toy is best?” but “what kind of input do they need”?
Most sensory toys fall into six groups:
Touch - fidget toys, textured balls, putty, sand and rice trays, fabric books, etc.
Weight and pressure - weighted lap pads, weighted blankets, cushions and compression vests. Pressure tends to feel calming for children, especially if they are neurodivergent.
Movement - swings, rockers, wobble boards, trampolines. For children who spin, rock and can’t sit still.
Sound - rainmakers, musical toys and white noise for children who find sound soothing, and ear defenders for those who need far less of it.
Sight - bubble tubes, projectors, liquid timers and light panels. Usually calming rather than exciting, and perfect at bedtime.
Mouth - chew necklaces, chewy tubes and teethers, for children who chew collars, cuffs and pencils.
Other questions to think about when choosing a sensory toy include:
-
Is it right for their age? Check the guidance on the packaging, and keep an eye out for small parts.
-
Can they use it alone, or will they need a hand or someone watching?
-
How noisy is it? Quiet enough for the classroom, the car or the dinner table?
-
Will it last? Chew toys and anything squeezed daily wear out fast.
-
Is it easy to clean? Most of it ends up in a mouth or on the floor.
The evidence behind sensory toys
So what does the research actually say? It's a more interesting picture than the marketing suggests.
The strongest findings are for deep pressure, meaning firm, steady pressure on the body, the sort you get from a weighted blanket or a weighted lap pad. A 2025 review of 21 controlled studies rated the evidence for it as strong, with improvements ranging from motor skills to sleep. The same review found that input across several senses works better than focusing on just one, which is a good argument for variety over a single expensive purchase.
For autistic children specifically, sensory integration therapy delivered by a qualified occupational therapist is now considered an evidence-based practice for ages four to twelve in the US.
Where the evidence thins is on specific product claims. The largest single trial of weighted blankets, involving 73 autistic children here in the UK, found they didn't help children fall asleep faster or wake less often, although children and parents clearly preferred them, and comfort counts for something.
Fidget toys are where it gets intriguing. Researchers at the UC Davis MIND Institute have found that fidgeting genuinely does help people with ADHD concentrate, and that the effect gets stronger the longer a task goes on. Their most recent work found 70 adults with ADHD performed better on cognitive tasks while fidgeting.
The catch is that natural fidgeting and a bought device aren't quite the same thing. Professor Julie Schweitzer, who led that research, says they're still investigating whether devices deliver the same benefit, and warns that some spinners are simply too distracting which is fair. That fits the one classroom trial we have: sixty children with ADHD lost attention more than twice as often when given a spinner.
Which makes sense really: the best fidget is the one you barely notice using.
What to check before you buy
Sensory toys are a hugely successful range of toys emerging in the market, with interest growing year on year according to Google Trends. This shows how many people have been searching for them in the UK since Google began. As you can see, this isn't a one off trend or a fad. Sensory toys are here to stay and the market is only getting stronger.
With any market growing this quickly, a small number of products end up causing problems, and unfortunately sensory toys are no exception. The vast majority are perfectly safe. But a handful have been recalled, and there are a couple of categories I'd always look at twice before buying. Here's what I would check.
Weighted products
Weight is the one category where you need to do your homework. In 2022, a children's weighted blanket was recalled after two girls, aged four and six, unzipped the cover, climbed inside and tragically suffocated. Never buy a weighted item your child can't get out from under on their own, never one with a cover they can get inside, and never use one with a baby.
Water beads
These turn up in sensory play ideas everywhere online, and the UK's Office for Product Safety and Standards issued a safety alert about them in October 2024. They swell up to 400 times their size in liquid, so a swallowed bead can block a child's gut and need surgery to remove. Keep them well away from under-fives, and supervise older children closely.
Small parts and chew toys. Check the age guidance on the packaging, and give anything destined for a mouth a quick look over before each use. Chew toys split as they wear, and a split chew toy is a choking hazard, so replace them at the first sign of damage.
I've flagged all that because I'd rather you heard it from us. But it's a short list, and it's very much the exception. Despite us profiting from these products, we also want to be as transparent as we can about these toys.
In Summary
Sensory toys are growing for a much better reason than fashion. We understand far more than we used to about how children take in the world, and how differently they can do it. Schools are more clued up, parents are more confident asking for what their child actually needs, and there's far less awkwardness these days about a child who has to chew, squeeze or move about in order to concentrate.
Even hospitals have adopted them. Queen's Medical Centre in Nottingham keeps sensory grab bags in its emergency department, filled with stress balls, fidget toys and ear defenders, for patients who find the place overwhelming.
That's the real story here. Not a fad, but a lot of people quietly working out that the right bit of input at the right moment makes a hard day easier. Which seems like a good enough reason for a shelf of its own.
