From the moment a baby startles at a loud noise or settles into a cuddle, their senses are already shaping how they understand the world. After more than seventeen years working with young children here in NSW, I’ve seen how sensory development systems sit at the heart of learning, behaviour, and wellbeing.
Children don’t experience life through one sense at a time. They take it all in at once. Movement, sound, touch, and internal body signals work together every day, often without us noticing.
Understanding the senses involved in sensory development helps families and educators support children with confidence, patience, and a good dose of common sense.
Why Sensory Development Shapes How Children Learn And Feel?
Sensory development is the process through which children receive information from their environment and their own bodies, then make sense of it. This information travels along sensory pathways to the brain, where it is organised and used to guide movement, behaviour, emotions, and learning.
In early childhood, this process is fast-paced. Neural connections form every time a child moves, listens, touches, tastes, or feels a shift in balance.
The Early Years Learning Framework reminds us that children learn best through active, hands-on experiences, and sensory input sits right at the centre of this approach.
I often think of a toddler we once supported who struggled during group time. He found it hard to sit still and became upset when the room grew noisy.
Once we adjusted the environment, added movement breaks, and gave him heavy work activities before mat time, his ability to engage improved almost overnight. His behaviour was not the issue. His sensory system was simply asking for support.
When sensory systems work well together, children are more likely to:
- Feel safe in their bodies
- Manage big emotions
- Focus on play and learning
- Build strong relationships
When sensory input feels overwhelming or confusing, children may appear restless, withdrawn, or easily frustrated. This is why understanding sensory development is so important, especially in the early years.
The Eight Sensory Systems Involved In Sensory Development
For many years, we spoke only about the five senses. While sight, hearing, touch, taste, and smell remain essential, current research shows there are eight sensory systems involved in sensory development. Each plays a different role, yet none works alone.
How Sensory Systems Work Together, Not In Isolation?
Sensory systems are like members of a busy team. Each has a job to do, but the real magic happens when they work together. This process is known as sensory integration.
Picture a preschooler climbing a ladder in the playground. Their eyes judge distance. Their vestibular system manages balance. Proprioception tells their muscles how much force to use. Tactile input from their hands helps with grip.
At the same time, they hear other children nearby and feel their heart rate rise with excitement. All of this information blends into one smooth experience.
Here’s a simple way to see how multisensory development unfolds over time:
|
Age Range |
Sensory Focus |
What This Often Looks Like |
|
Birth–12 months |
Touch, movement, sound |
Grasping, mouthing, rocking, responding to voices |
|
1–3 years |
Balance and body awareness |
Climbing, pushing, spinning, testing limits |
|
3–5 years |
Integration of all systems |
Coordinated play, improved focus, emotional awareness |
In early learning settings across NSW, we plan environments with this in mind. Outdoor play, sensory play, music, and quiet spaces all support sensory integration by giving children the “just right” amount of input.
When children receive the sensory input they need, learning flows more easily. When they don’t, it can feel like trying to paddle upstream without a paddle.
The Five External Senses In Sensory Development
The five external senses help children gather information from the world around them. These senses develop at different stages and continue to refine throughout early childhood.
In practice, I’ve found that when we support these senses through play and everyday routines, children feel more settled and ready to learn.
Sight – How Visual Processing Supports Learning And Focus?
Sight is the least developed sense at birth. Newborns can only see about 20–30 centimetres ahead, which explains why faces close to theirs draw their attention first. Over time, visual skills such as tracking, colour recognition, and depth perception strengthen.
In early learning rooms, this shows up when children begin matching shapes, completing puzzles, and following simple visual instructions.

Hearing – Sound, Language, And Emotional Safety
Hearing develops before birth. Babies recognise familiar voices and rhythms early on, which is why gentle singing and consistent tone matter so much.
In childcare settings, predictable routines and calm voices help children feel secure, especially during transitions. I’ve seen children settle more quickly when background noise is reduced and instructions are short and clear. Sometimes less really is more.
Touch – Building Comfort And Body Awareness
The tactile system develops first and plays a key role in bonding and emotional regulation. Touch helps children understand texture, pressure, and boundaries.
Messy play, sand, water, and playdough allow children to explore safely. A child who avoids certain textures is not being difficult. Their sensory system is communicating.
Smell – Memory And Emotional Connection
Smell is closely linked to memory and emotion. Familiar scents can calm children, while strong or unexpected smells may cause discomfort.
In early learning environments, keeping scents neutral supports children who are sensitive to olfactory input. It’s a small change that can make a big difference.
Taste – Sensory Learning Through Food
Taste develops early, with newborns preferring sweet flavours. As children grow, repeated exposure supports acceptance of new foods.
Mealtimes become sensory learning moments when children explore food at their own pace, without pressure.
The Hidden Senses That Support Movement And Regulation
Beyond the five external senses, three internal systems guide balance, movement, and self-awareness. These senses often explain behaviours we see every day in young children.
Vestibular Sense – Balance And Movement
The vestibular system sits in the inner ear and manages balance and movement. Children often seek this input through spinning, swinging, and climbing.
In our outdoor spaces, we intentionally include opportunities for safe risk-taking because movement helps children regulate their emotions and focus later on.
Proprioception – Body Awareness And Control
Proprioception gives feedback from muscles and joints. It tells the brain where the body is and how much force to use.
Proprioceptive Activities Children Often Seek
- Carrying heavy objects
- Pushing furniture
- Jumping or crashing into cushions
These activities help children feel grounded and organised.
Interoception – Understanding Internal Body Signals
Interoception helps children recognise hunger, thirst, tiredness, and emotional cues. This sense supports self-regulation.
A preschooler who melts down late in the afternoon may not have the words to say they are exhausted. Their body is doing the talking.
How Sensory Systems Work Together In Daily Learning?
Sensory development in early childhood is not about single activities. It is about consistent, meaningful experiences that allow sensory pathways to strengthen.
When children climb, paint, listen to stories, and rest, their sensory systems work together. This supports attention, emotional control, and confidence.
Quick Sensory Support Checklist
- Provide daily outdoor movement
- Balance active and quiet play
- Offer varied textures and materials
- Keep routines predictable
When sensory needs are met, learning feels less like hard work and more like second nature.
Additional Sensory Pathways That Support Safety And Awareness
Alongside the eight main sensory systems, there are other sensory pathways that play a quiet but important role in keeping children safe and comfortable. These systems often work in the background, yet they shape how children respond to everyday experiences.
Nociception – How Children Understand Pain And Safety?
Nociception is the sense that alerts the body to pain. It acts as an early warning system, helping children learn what is safe and what is not. A scraped knee or a bumped elbow teaches cause and effect in a very real way.
In early learning settings, we follow NSW safety regulations that balance risk and protection. Children are allowed to climb, run, and explore, while educators supervise closely.
Small risks support learning. Pain, when managed calmly, helps children build awareness and resilience rather than fear.
Thermoception – Awareness Of Temperature And Comfort
Thermoception allows children to sense heat and cold. This sense guides choices such as seeking shade on a hot day or reaching for a jumper when it cools down.
In NSW, where the weather can swing from warm mornings to cooler afternoons, children rely on adults to help interpret these signals. Supporting children to notice how their bodies feel builds independence and self-care skills over time.
How Sensory Integration Supports Learning And Behaviour?
Sensory integration is the brain’s ability to organise sensory input so the body can respond in a coordinated way. When this process runs smoothly, children move with confidence, manage emotions, and stay engaged in play and learning.
What It Looks Like When Sensory Systems Work Well Together?
When sensory systems are balanced, children can:
- Sit and listen during group time
- Move safely through their environment
- Adjust their behaviour to different settings
- Recover from emotional upsets more quickly
I’ve watched children who once struggled to participate grow in confidence after small changes were made. Adding movement before seated tasks or creating quiet corners often shifts behaviour without a single word being said.
Sensory Processing Differences In Early Childhood
Some children experience sensory input more intensely, while others seek extra input to feel organised. These differences are part of normal development, not a reflection of parenting or behaviour management.
Common Sensory Processing Patterns
|
Pattern |
What It May Look Like |
|
Sensory seeking |
Constant movement, crashing, loud play |
|
Sensory avoiding |
Covering ears, avoiding textures |
|
Sensory sensitivity |
Strong reactions to noise or light |
|
Low registration |
Appearing unaware or slow to respond |
Understanding these patterns helps adults respond with empathy rather than frustration.
Sensory Development In Early Childhood Settings
Early learning environments play a key role in supporting sensory development in children. Under the EYLF, children are viewed as active participants in their learning, and sensory experiences support this approach naturally.
Why Sensory Play Builds Strong Learning Foundations?
Sensory play engages multiple senses at once. This strengthens sensory pathways and supports language, problem-solving, and social skills.
Activities such as water play, mud kitchens, and music sessions allow children to explore freely while building confidence and curiosity.
Everyday Sensory Experiences That Support Development
Common Early Learning Examples
- Climbing and balancing outdoors
- Painting with brushes, hands, and sponges
- Listening to stories with actions
- Resting in quiet spaces after busy play
These experiences are simple, yet powerful.
Simple Ways Families Can Support Sensory Awareness At Home
Families often support sensory learning without realising it. Everyday routines provide rich sensory input when children are given time and space to explore.
Practical Sensory Activities At Home
- Cooking and tasting new foods
- Gardening and digging
- Bath play with cups and sponges
- Walking barefoot on grass or sand
These activities strengthen sensory learning through real-life experiences.
When Extra Support May Help?
If a child consistently struggles with regulation, sleep, or daily routines, families may consider speaking with their GP or an allied health professional. Early guidance supports children and families alike.
Sensory development is not an add-on to learning. It is the groundwork. From the five external senses to the hidden systems that guide balance, body awareness, and internal signals, each sensory pathway helps children make sense of their world.
When these senses work together, children feel secure, capable, and ready to learn. In early childhood, small everyday experiences shape this development in lasting ways.
By understanding the senses involved in sensory development, families and educators can respond with greater insight, support children with confidence, and create environments where every child has the chance to thrive.
