it’s not just emotions:
understanding your child’s nervous system
Is Emotional Regulation just about your emotions?
Emotional regulation is often described as something children can master through reminders, practice, or self-control. Parents are encouraged to help their child calm down, use their words, or manage big feelings. Yet for many families, this explanation doesn’t fully reflect what they see day to day.
You might notice your child copes well one day and struggles the next, or that a transition they managed yesterday suddenly feels overwhelming. School drop-off, after-school routines, or simply leaving the house can look entirely different depending on the day — even when nothing obvious has changed. That inconsistency can feel confusing, exhausting, and at times disheartening.
But what if emotional regulation isn’t just about emotions? What if it’s about a developing nervous system still learning how to navigate a busy, demanding world?
What is Polyvagal Theory?
Polyvagal Theory offers a helpful framework for understanding why children can cope well one day and struggle the next. It explains how the nervous system is constantly and automatically scanning the environment, relationships, and the body for cues of safety or threat — outside of conscious awareness. At a subconscious level, a child’s body is always asking, “am I safe enough right now?” to determine what to do next.
In the Polyvagal theory, safety and threat aren’t about actual danger. They’re about how the nervous system interprets what’s happening, based on sensory information from both outside and inside the body.
The nervous system takes in information through the senses — sight, sound, touch, and smell — as well as from within the body, including balance, body awareness, muscle activation, breathing, fatigue, hunger, and daily rhythms. When this input feels organised and manageable, the world is more likely to be experienced as safe. When it feels overwhelming, unpredictable, or difficult to process, the nervous system may register threat — even when nothing dangerous is happening.
What Are The Three Main States of the Nervous System?
Polyvagal Theory describes three main nervous system states that children move through across the day. These states are neither good nor bad. They are protective responses designed to help the body cope based on what it feels it needs.
The Ventral State
The Ventral System is activated when a child’s nervous system feels safe enough. This state supports connection, learning and emotional flexibility and children can often engage with others, communicate, play and cope with everyday challenges. Emotions still come and go, but they are more manageable.
A child might feel frustrated or disappointed, but they can recover with support. This is often the version of your child you recognise most easily; curious, warm, playful and capable.
- At home: they may enjoy play, conversation and connection.
- At school: this may look like a child who can participate in group time, follow routines, engage in learning or accept help.
- In the community: they are more able to tolerate change and differing sensory inputs.
The Sympathetic State
The Sympathetic system is activated when the child’s nervous system starts to feel overwhelmed. This is the state of mobilisation, protection, agitation or feeling frantic. The body prepares for action to find an internal sense of safety, such as the need to escape, defend or regain control. This is not a child choosing to misbehave, it is the nervous system responding to a load that it cannot currently cope with. A child may appear anxious, restless, angry, or explosive. You might see meltdowns, yelling, hitting, running away, refusing tasks or constant movement.
- At home: this may also show up during everyday routines that place multiple demands on the body at once. For example, a child may become dysregulated during the evening routine, resisting getting dressed, shouting during dinner, or becoming upset over small requests.
- At school: this can look like difficulty sitting still, emotional outbursts, struggling with transitions or difficulty engaging with peers.
- In the community: this can occur in situations that require constant scanning and adjustment. A child may become anxious or reactive when entering a birthday party, sports game, or busy cafe, especially when there is loud noise, unpredictable movement, and social expectations.
The Dorsal State
The Dorsal State is activated when a child’s nervous system is overwhelmed. This is the state of shutdown or collapse. When stress feels too much and escape doesn’t feel possible, the nervous system slows everything down to protect itself. A child may withdraw, go quiet, zone out, avoid interaction or appear flat and exhausted.
- At home: they may collapse after school, retreat to their room or struggle to engage or communicate.
- At school: they may sit quietly, not ask for help and slip under the radar.
- In the community: they may avoid participation altogether, seeking close contact with a parent or avoid interacting with others.
This response is often misunderstood as a lack of motivation or disinterest, when in fact it is a nervous system trying to cope.
Why is there no predictability with my child’s emotions and ability to cope everyday?
One of the hardest things for parents is how quickly and unpredictably children can shift between states. A child may cope well in one environment but struggle in another because the nervous system responds to the total load it’s carrying — not just what’s happening in the moment. Sleep, sensory input, social demands, emotional stress, fatigue, hunger, excitement, and change all build up across the day.
Sensory processing and motor development play a significant role. For children who find it difficult to organise sensory input or who have delays in postural control and movement, everyday tasks can require far more effort. Sitting upright, filtering background noise, coordinating movement, or simply feeling grounded in their body can be exhausting. When the body doesn’t feel steady, the nervous system reaches overload more quickly and takes longer to return to a calm, connected state.
Viewed through this lens, behaviour begins to make different sense. Instead of asking, “why is my child doing this?” we might ask, “what state is their nervous system in — and what does their body need right now?”
How does Explore and Soar help through Polyvagal Theory?
We use this framework to support children and families at a foundational level, looking beyond behaviour to understand nervous system states, sensory processing, and motor development. In therapy, we prioritise safety, connection, movement, and sensory support before expecting engagement or skill use.
We also ensure parents, teachers, and educators are supported to understand what they’re seeing at home, school, and in the community. Through shared understanding, training, and practical strategies embedded across everyday environments, regulation becomes more predictable and less confusing for both the child and their supports.
When emotional regulation is viewed through a nervous system lens, behaviour tells a different story — a body still learning, a nervous system doing its best to manage the world. By meeting children at this level, meaningful change can unfold. Rather than pushing harder, we respond to what their nervous system has been asking for all along.
We love being able to foster and support this change with our children and parents. If this resonates with you, chat to your treating clinician in your next therapy session or enquire to learn more from us today or call 0477 708 217.
Until next time,
Maddie
