What is Sensory Sensitivity? A Guide for Parents
If you are a parent to a neurodivergent child—perhaps they are autistic or have ADHD—you might have noticed that they experience the world a little differently. Maybe they cover their ears when the vacuum is on, refuse to wear socks with seams, or perhaps they are the opposite: they love crashing into the sofa and crave the tightest of bear hugs.
This is sensory sensitivity. It is incredibly common, and it simply means that your child’s brain processes the information coming in from their senses differently to a neurotypical brain.
Up to 1 in 6 children experience sensory processing differences, and it is especially common in our neurodivergent kids. What feels like a completely normal environment to us can feel incredibly intense, loud, or uncomfortable for them.
Understanding how your child processes the world is the first step to supporting them. When we know what is happening in their brain, we can move away from thinking "why are they acting like this?" and instead ask, "what is their environment telling them right now?"
How Does Sensory Sensitivity Work?
For most of us, our brains automatically filter out background noise. We do not constantly feel the tag on the back of our shirt, we tune out the hum of the refrigerator, and we barely notice the fluorescent lights at the supermarket.
But for a child with sensory sensitivities, that filter works differently. Those everyday sights, sounds, and feelings can feel impossible to ignore. This difference in processing usually shows up in two main ways:
Sensory Overload (Hypersensitivity)
When a child is exposed to too much sensory input, they can feel completely overwhelmed. Their brain struggles to process all the incoming information at once, leading to distress, anxiety, or a "meltdown." A child experiencing sensory overload might cover their ears, close their eyes, hide under a table, or try to run away from the environment.
Sensory Seeking (Hyposensitivity)
On the other hand, some children have a reduced sensitivity to their environment. Their brains actually need stronger, more intense input to register the sensation and feel calm. These children might actively seek out loud noises, crave deep pressure like tight hugs, enjoy crashing into things, or need to constantly fidget and move to feel regulated.
It is also very common for a child to be a sensory seeker in one area (like needing deep pressure) but experience sensory overload in another (like being overwhelmed by loud noises).
The 5 Types of Sensory Sensitivity
Sensory sensitivity can affect any of the five senses. Every child is wonderfully unique, and their sensory profile will be too.
1. Auditory (Hearing) Sensitivity
Children with auditory sensitivity may find everyday sounds distressing. Background noise that others easily tune out can feel overwhelmingly loud or even painful.
What it looks like: Covering ears when the hand dryer goes off in a public toilet, distress in crowded rooms, or anxiety when multiple people are talking at once.
2. Visual (Sight) Sensitivity
Visual sensitivity means a child is easily overwhelmed by what they see. They may prefer dim lighting and find busy, visually cluttered environments stressful.
What it looks like: Squinting in bright sunlight, distress under fluorescent lighting, or feeling overwhelmed in rooms with very busy, high-contrast patterns.
3. Tactile (Touch) Sensitivity
Tactile sensitivity involves a heightened reaction to physical touch and textures. A child might find certain clothing unbearable or resist being touched unexpectedly.
What it looks like: Refusing to wear clothes with tags or seams, distress over sticky hands, avoidance of certain food textures, or pulling away from light, unexpected touch.
4. Olfactory (Smell) Sensitivity
Children with olfactory sensitivity have a highly tuned sense of smell. Scents that others barely notice can be completely overpowering, sometimes even causing physical discomfort.
What it looks like: Gagging at the smell of cooking, distress around strong perfumes, or avoidance of certain cleaning products.
5. Gustatory (Taste) Sensitivity
Gustatory sensitivity relates to how a child experiences the taste and texture of food. This is often misunderstood as simply being a "fussy eater," but it is actually a very real sensory response to the feeling or flavor of the food in their mouth.
What it looks like: Avoiding bitter or spicy flavors, distress over mixed textures (like lumps in yogurt), or refusing foods that feel slimy or mushy.
Practical Ways to Support Your Child at Home
While sensory sensitivity can present challenges, there are many gentle, practical ways to support your child and help them feel more comfortable in their environment.
Create a Sensory-Safe Space
Designate a quiet, calm corner in your home where your child can retreat when they feel overwhelmed. This does not need to be a large space—a small pop-up tent or a cozy nook with soft pillows and dim lighting works perfectly. Having a dedicated safe space gives them a chance to decompress and self-regulate when the world feels like too much.
Introduce Calming Sensory Tools
Sensory tools can be incredibly helpful for managing both sensory overload and sensory seeking behaviors. Items like weighted blankets can provide deep, calming pressure that soothes an overwhelmed nervous system. Noise-canceling headphones can offer immediate relief in loud environments like shopping centers. Fidget toys are also excellent for helping sensory seekers focus and regulate their energy throughout the day.
Build Predictable Routines
Because anxiety can heighten sensory sensitivity, keeping a predictable daily routine can be very reassuring for your child. When changes do need to happen—like the start of the school holidays—giving them plenty of warning and explaining exactly what to expect can help ease the transition.
Moving Forward Together
Sensory sensitivity is a unique part of how your child experiences the world. By understanding their specific triggers and the ways they process sensory information, you can create an environment that feels safe, supportive, and nurturing.
Whether it is through adjusting the lighting in their bedroom, removing scratchy clothing tags, or introducing calming sensory tools, small changes can make a world of difference in helping your child feel calm, confident, and ready to engage with the world around them.
