An Introduction to Sensory Issues in Kids

Did you know that 1 in 6 children today struggles with sensory processing challenges? Sensory issues are more common than many parents realize and can affect everything from how a child tolerates clothing textures to how they respond to everyday sounds and lights.

While most kids enjoy exploring the world around them, children with sensory challenges can feel overwhelmed by normal experiences. That was true for Tierney, who could only wear loose-fitting dresses because seams and certain fabrics were too distressing for her nervous system. With the natural, drug-free strategies discussed in this article, she was able to overcome her sensory struggles and now thrives with confidence.

In this article, we’ll explore what sensory issues are, how they show up, and practical ways to help sensory kids and their families thrive.

Defining Sensory Issues

Sensory issues, also known as sensory processing difficulties or Sensory Processing Disorder (SPD), encompass a range of challenges that involve how the nervous system receives, processes, and responds to sensory stimuli. While most of us think of the traditional five senses,  sight, sound, touch, taste, and smell, sensory processing actually involves seven senses.

Back in the 1970s, occupational therapist A. Jean Ayres, PhD, introduced a groundbreaking sensory integration theory that changed how we understand sensory processing. Dr. Ayres identified that certain people’s brains struggle with what most of us take for granted: processing all the information coming in through these seven senses to provide a clear picture of what’s happening both internally and externally.

The Seven Senses Include:

1. Touch (Tactile)
2. Sight (Visual)
3. Sound (Auditory)
4. Taste (Gustatory)
5. Smell (Olfactory)
6. Body Awareness (Proprioception), knowing where your body is in space
7. Movement and Balance (Vestibular), understanding motion and spatial orientation

When working properly, the sensory nervous system does an incredible job of receiving sensory information from both the external and internal environment, integrating it into the brain, and coordinating the proper decisions and actions to take in response. 

This process is called sensory modulation; it’s how the brain filters and organizes sensory input to respond appropriately. Sensory processing and integration are essential elements of overall neurological functioning and development.

However, children with sensory issues may exhibit hypersensitivity (over-sensitivity) or hyposensitivity (under-sensitivity) to various stimuli in their environment, which can have significant implications for their daily lives.

These issues are often associated with conditions like Autism Spectrum Disorder. Sensory issues can affect various aspects of a child’s life, from their behavior and emotions to their social interactions and learning experiences. Identifying and addressing these challenges early on is crucial for providing the necessary care and support.

Prevalence and Impact on Child Development

Sensory issues are more common than we might think. Research indicates that they can be present in children both with and without diagnosed developmental conditions. Many recent analyses have shown it could be as high as 1 in 6 kids born today. 

These challenges can significantly impact a child’s development and quality of life, making it imperative to foster awareness and understanding on a larger scale and then make appropriate care options available to more families.

The average pediatrician and medical provider still today not only will often completely overlook and miss sensory issues in your child but will often even dismiss them as “completely normal” and say something to the effect of “don’t worry, they’ll grow out of it,” which is simply not the case.

It’s also important to understand how sensory issues relate to other neurodevelopmental conditions. Many children with ADHD or anxiety also struggle with sensory processing, and these challenges can compound one another, making daily functioning even more difficult.

Common Types of Sensory Issues in Kids

Children with sensory processing challenges are often labeled as “sensory avoiders” or “sensory seekers” based on how their nervous system responds to input. Some kids can be a mix of both, depending on the situation and type of sensory stimulation.

Over-Sensitivity (Hypersensitivity), Sensory Avoiders

Children with hypersensitivity can find everyday sensations overwhelming. Their nervous system interprets normal sensory input as threatening or painful, triggering what’s called a fight-or-flight response even in safe situations. Here are common types of sensory hypersensitivity:

• Auditory Sensitivity: Even soft sounds might feel painfully loud to these children. Noisy environments, such as crowded classrooms, grocery stores, or busy streets, can trigger anxiety or meltdowns. Your child might cover their ears frequently or seem distressed by sounds that don’t bother others.
• Visual Sensitivity: Bright lights, flickering screens, fluorescent lighting, or intricate patterns might cause discomfort or even pain for children with visual sensitivity. They may squint often, avoid bright spaces, or complain about lights that seem normal to everyone else.
• Tactile Sensitivity (Tactile Defensiveness): Some children might be highly sensitive to touch, finding certain fabrics, tags on clothes, seams in socks, or even a gentle pat on the back uncomfortable or unbearable. They may resist hugs, avoid messy play, or have strong reactions to having their hair brushed or nails trimmed.
• Olfactory Sensitivity: Strong smells that most of us barely notice, like perfumes, cleaning products, or certain foods, can be intense and bothersome for children with olfactory sensitivity. They may gag easily or refuse to enter spaces with particular scents.
• Gustatory Sensitivity: Certain food tastes and textures may trigger strong reactions, making mealtimes a challenge for children with gustatory sensitivity. These aren’t just “picky eaters,” their nervous system genuinely struggles to process certain food sensations, leading to limited diets and nutritional concerns.

Impact on Motor Skills: Hypersensitive children often struggle with fine motor skills like buttoning clothes, holding a pencil properly, or using scissors because even a gentle touch feels overwhelming. They may also avoid gross motor activities, such as playground equipment or sports, due to fear of unexpected physical sensations.

Under-Sensitivity (Hyposensitivity), Sensory Seekers

On the other end of the spectrum, some children have hyposensitivity, meaning they have a reduced response to sensory stimuli. Their nervous system requires more intense input to register sensations, leading to sensory seeking behaviors.

• Proprioceptive Seeking: Children might seek out deep-pressure activities, such as tight hugs, crashing into furniture, jumping from heights, or engaging in rough play, to satisfy their proprioceptive needs. They may appear “clumsy” because their body awareness is reduced, they don’t know their own strength, and might hug too hard, throw things too forcefully, or bump into objects frequently.
• Vestibular Seeking: Swinging, spinning, hanging upside down, or other intense movement-based activities might be craved by children with vestibular sensitivity. They may seem like they never stop moving, constantly rocking, spinning in circles, or seeking extreme playground activities.
• Sensory Seeking Behaviors: Some children engage in repetitive sensory seeking behaviors, such as rocking, spinning, hand-flapping, or touching everything they encounter to stimulate their sensory systems. They may also seek out loud sounds, bright lights, or strong flavors.
• Motor Planning Challenges: Hyposensitive children often struggle with motor planning (also called praxis), the ability to plan and execute coordinated movements. They may have trouble learning new physical tasks, appear uncoordinated, or struggle with activities requiring multiple steps, like getting dressed or tying their shoes.

Identifying Sensory Issues in Children

Identifying sensory issues can be challenging because children’s responses to sensory stimuli vary widely. Understanding the signs across different age groups is crucial for early intervention. Think of this as a sensory checklist to help you observe your child’s responses to everyday situations.

Signs in Different Age Groups 

In infants, signs might include:

• Excessive crying
• Difficulty feeding
• Arching away from being held
• Avoiding certain textures
• Trouble sleeping. 

In toddlers and older children, you may notice:

• Difficulties with dressing, grooming
• Sensitivity to specific textures like clothing tags or sock seams. 
• Frequent tantrums, meltdowns, and behavioral issues in this age group can also be signs of sensory issues and sensory overload.

Red Flags to Watch For:

• Covering ears in normal-noise environments
• Refusing to wear certain clothing or go barefoot
• Extreme reactions to having hair washed, cut, or brushed
• Avoiding messy play (paint, sand, play-dough)
• Seeming oblivious to pain or temperature
• Poor fine motor skills, trouble with buttons, zippers, or holding a pencil
• Struggling with gross motor coordination, difficulty catching a ball, riding a bike, or climbing stairs
• Seeking intense physical input – crashing, jumping, spinning excessively
• Picky eating beyond normal preferences
• Difficulty with transitions and changes in routine

Differentiating Sensory Issues from Typical Behavior: It’s essential to differentiate sensory issues from normal childhood behavior. While most children might be picky eaters at times, a child with sensory challenges might struggle to consistently tolerate certain textures. The key difference? Intensity, duration, and impact on daily functioning. If your child’s reactions are extreme, frequent, and interfere with everyday activities like getting dressed, eating meals, or going to school, it’s time to look more deeply.

Seeking Professional Evaluation and Diagnosis: If you suspect your child is experiencing sensory issues, a professional evaluation is vital. While traditionally, parents are told to seek out occupational therapists, developmental pediatricians, and child psychologists for evaluation and management, many parents today are turning to Neurologically-Focused Pediatric Chiropractors to address the root cause of their child’s sensory issues head-on, something we’ll discuss in full in the next section.

INSiGHT Scans: The Missing Piece in Sensory Assessment

Here’s what makes our approach at PX Docs entirely different: we don’t just observe behaviors and fill out questionnaires; we can actually measure what’s happening in your child’s nervous system. Our INSIGHT scanning technology provides objective data about the neurological dysfunction driving sensory issues.

These scans measure three critical things: 

• The amount of sympathetic (fight-or-flight) stress in your child’s system
• How well their nervous system is adapting and regulating
• Where subluxation is interfering with proper sensory processing. 

We can literally see if your child’s nervous system is stuck in that stressed, survival mode we’ve been talking about. The scans show us exactly where the interference is, often in the upper cervical spine affecting the vagus nerve and brainstem, and track improvement over time as we address it.

We also have the ability to run what is effectively a Sensory Processing Disorder Test, which measures subluxation and neurosensory dysfunction that is the underlying cause of sensory issues in kids.

The “Perfect Storm”: What Really Causes Sensory Issues in Kids

After 15+ years of working with thousands of children struggling with sensory processing challenges, we’ve identified a clear pattern, what we call the “Perfect Storm.” This isn’t about making you feel guilty. What we’re talking about is the accumulation of neurological stress that starts before your child is even born.

Stage 1: Prenatal Stress

Research shows that maternal stress during pregnancy directly impacts fetal nervous system development. When mom’s stressed, cortisol and stress hormones cross the placental barrier and affect the developing baby’s nervous system. Work pressures, relationship challenges, and health complications; this prenatal stress primes the baby’s nervous system to be on high alert before they’re even born.

Stage 2: Birth Trauma and Intervention

Birth trauma, physical stress to the baby’s neck, head, and nervous system during delivery, is far more common than most parents realize. Modern birth interventions put significant stress on a baby’s delicate nervous system:

• Forceps or vacuum extraction – Intense pulling force on the head and neck
• Emergency C-sections – Aggressive extraction after hours of labor
• Induction with Pitocin – Stronger contractions, often leading to cascade interventions

Here’s what matters: The upper cervical spine houses the brainstem and vagus nerve pathway, the #1 most crucial sensory processing nerve in the body. When birth trauma causes subluxation here, it disrupts the foundation of sensory processing. Studies show a direct connection between cesarean delivery and increased sensory processing challenges.

Stage 3: Early Childhood Stressors

Once a baby is born with a stressed nervous system, impacted by birth trauma, additional stressors often tip them over the edge:

• Medical interventions – Repeated antibiotics, reflux medications, rapid vaccination schedules
• Environmental factors – Pesticides, plastics, heavy metals, air pollution
• Ongoing health challenges – Chronic ear infections, digestive issues (colic, constipation), sleep disturbances

The Accumulation Principle

It’s not JUST the pregnancy, birth, or antibiotics alone. It’s the accumulation of stressors hitting a vulnerable nervous system. Think of it like a stress bucket; each stressor adds more until it overflows, showing up as sensory processing challenges.

This is why siblings have different outcomes. Why do some C-section babies do fine while others struggle? Why does your child seem “normal” then suddenly hit a developmental wall?

From “Perfect Storm” to Sensory Storm

When you combine prenatal stress, birth trauma creating subluxation and vagus nerve dysfunction, and early childhood stressors, you get a nervous system stuck in fight-or-flight mode. Everything feels threatening. Tags feel like knives. Sounds feel like alarms. Touch feels painful.

Your child isn’t “too sensitive.” Their nervous system is doing what it’s designed to do when it perceives constant threat. The good news? Once you understand the “Perfect Storm,” you can address its root cause rather than just managing the symptoms.

The Role of Subluxation, Dysautonomia, and the Vagus Nerve in Sensory Issues

Just like sensory issues and challenges in kids are too easily overlooked by both parents and pediatricians, so is the root cause, an overly stressed and out-of-balance nervous system stuck in fight-or-flight response.

Here’s what’s really going on: when your child’s nervous system gets stuck in that “fight-or-flight” state (what we call sympathetic dominance), their brain interprets normal sensory input as threatening. It’s like their gas pedal is stuck down and their brake pedal isn’t working; everything feels more intense, more overwhelming, and more dangerous than it really is.

To fully understand what’s causing sensory issues in kids, we’ve got to quickly introduce and define four important terms that are all interrelated:

1. Subluxation: Subluxation occurs when the nervous system has become overstressed and out of balance, disrupting sensory processing and communication into the brain and central nervous system. Think of it as a stuck on-off switch that interferes with how your child’s brain receives and interprets sensory information.
2. Dysautonomia: When subluxation is present and the nervous system gets out of balance, that is called dysautonomia. This most commonly presents first with an overstressed and overstimulated Sympathetic Nervous System (“fight or flight” – the gas pedal) and then, in turn, a suppressed or underactive parasympathetic (“rest + regulate,” the brake pedal) side of the nervous system.
3. Vagus Nerve Dysfunction: The vagus nerve is the #1 most crucial sensory processing nerve in the body and controls and regulates most parasympathetic calming and regulating functions. When the vagus nerve isn’t working properly due to subluxation or birth trauma, your child loses their primary “brake pedal” for calming down and regulating their sensory system.
4. Nervous System Dysregulation: Nervous system dysregulation refers to a malfunction or imbalance within the nervous system, which affects its normal functioning and capacity to regulate responses to stimuli. This can manifest in various ways, ranging from physiological to emotional and cognitive disturbances – including how your child processes sensory information.

The Impact of Sensory Issues on Daily Life

Sensory processing challenges don’t just affect your child during specific moments; they ripple out to impact nearly every area of their development and daily functioning.

Challenges in Education and Learning

Sensory issues can profoundly affect a child’s ability to concentrate in a classroom environment. Bright fluorescent lights, loud noises from classmates, the feeling of their clothing, or even the smell of cleaning products might become overwhelming distractions that make learning nearly impossible. Teachers may misinterpret their behavior as not paying attention or as being defiant, when, in fact, their nervous system is in sensory overload.

Beyond attention, sensory challenges often impact executive function, the brain’s ability to plan, organize, and follow through on tasks. Children with sensory processing difficulties may struggle with:

• Getting started on assignments
• Organizing their materials and workspace
• Following multi-step directions
• Transitioning between activities
• Managing time effectively

Social and Emotional Implications

Children with sensory challenges might struggle with social interactions due to their heightened sensitivity to touch, sound, or visual stimuli. They may avoid playdates, birthday parties, or group activities because these situations are sensory minefields. Social isolation often follows, as other kids don’t understand why their friend won’t participate in normal childhood activities.

This social withdrawal can lead to:

• Low self-confidence and self-esteem
• Feeling “different” or “broken” compared to peers
• Difficulty making and keeping friends
• Anxiety about social situations
• Depression in older children and teens who feel increasingly isolated

Family and Caregiver Dynamics

Coping with a child’s sensory issues can be demanding for families and caregivers. Simple outings like grocery shopping, family dinners at restaurants, or attending siblings’ school events can become sources of stress rather than joy. Understanding and accommodating these challenges is crucial for maintaining healthy family dynamics, but it’s exhausting when you feel like you’re constantly walking on eggshells or missing out on normal family experiences.

Gut and Immune Health

Since sensory processing challenges put extra stress and tension on the child’s nervous system as a whole, this may create a “spillover” effect, where other important bodily functions, like digestion and immune function, are interfered with and suppressed as well. Most children with SPD and ASD challenges also have gut and immune issues. 

When the nervous system is stuck in fight-or-flight mode, it diverts resources away from digestion and immune response; it thinks you’re running from danger, not trying to digest lunch or fight off a cold.

Do Sensory Issues Get Better with Age?

This is one of the most common questions parents ask: “Will my child grow out of this?”

The truth is, sensory issues rarely disappear on their own, but they can significantly improve with the right support. Some children develop better coping strategies as they mature and learn to anticipate and manage triggering situations. However, without addressing the underlying nervous system dysfunction, sensory challenges often persist into adolescence and adulthood, just with different manifestations.

The good news? Early intervention, especially when it addresses the root neurological causes rather than just managing the signs, can lead to dramatic improvements. We’ve seen countless kids who struggled with severe sensory processing challenges go from being unable to tolerate everyday situations to thriving in environments that once overwhelmed them.

Coping Strategies for Children with Sensory Issues

While understanding the root neurological causes is critical, there are also practical strategies that can help your child navigate daily challenges while you’re addressing the underlying dysfunction.

Creating a sensory-friendly home environment. Adjusting the home environment to accommodate sensory needs can make a significant difference. Providing quiet spaces, using sensory-friendly fabrics, minimizing clutter, controlling lighting levels, and reducing background noise are helpful steps. Some families create a dedicated “calm corner” or sensory space for their child to retreat to when overwhelmed.

The Role of Occupational Therapy (OT): Occupational therapy with a sensory integration approach is the most common conventional care for sensory processing challenges. OTs work with children in what’s often called a “sensory gym,” a specialized, sensory-rich environment designed to provide controlled sensory input.

During OT sessions, therapists use activities like:

• Swinging and spinning for vestibular input
• Weighted vests or compression garments for proprioceptive feedback
• Tactile exploration with different textures
• Balance and coordination exercises
• Fine and gross motor skill development

The goal is to help your child’s nervous system process and respond to sensory information more effectively through what’s called “sensory integration therapy.”

You may hear occupational therapists recommend a “sensory diet,” not a food diet, but a personalized plan of sensory activities scheduled throughout the day to help children regulate their responses to sensory stimuli. Think of it as physical therapy for the nervous system.

A sensory diet might include:

• Deep pressure activities (bear hugs, weighted blankets)
• Movement breaks (jumping on a trampoline, spinning)
• Calming activities (rocking, listening to soft music)
• Alerting activities (crunchy foods, cold water on face)
• Organizing activities (pushing/pulling heavy objects)

The key is matching the activities to your child’s specific needs, whether they need more input (sensory seekers) or help filtering out overwhelming input (sensory avoiders).

For hypersensitive children, gradual exposure to troubling sensory experiences can help. This might look like:

• Spending just a few minutes in a noisy store, gradually increasing the time
• Starting with loose-fitting clothes and slowly introducing fitted garments
• Beginning with preferred food textures and slowly adding new ones

The approach should always be gentle and child-led, never forcing exposure that triggers genuine distress.

Working closely with teachers and educators to implement sensory-friendly strategies in the classroom can greatly support a child’s learning experience. This might include preferential seating away from distractions, movement breaks, fidget tools, or wearing noise-canceling headphones during loud activities.

What If You’ve Done All That and Nothing Has Worked?

After 15+ years of caring for kids with sensory challenges, I’ve heard the same story from countless parents: “We’ve tried everything.” OT, sensory diets, breathing exercises, supplements, yet when stress hits, the meltdowns and sensitivities come right back. If that sounds familiar, you’re not alone. And you’re not crazy.

Here’s why this happens: most therapies work downstream. They help manage symptoms and teach coping skills, but they don’t address the upstream issue—a stressed, stuck nervous system. It’s like patching symptoms without fixing the root problem. If the nervous system is still locked in fight-or-flight mode, progress can only go so far.

Neurologically-Focused Chiropractic Care aims to address those root causes by identifying and reducing nervous system stress. Using objective scans and gentle, specific adjustments, the goal is to calm the system, support vagus nerve function, and improve sensory regulation, helping kids better tolerate clothing, busy environments, and everyday life so families can truly thrive.
