Understanding behaviour as communication
Children often communicate their internal experiences through behaviour, particularly when they do not yet have the language to explain how they feel.
This is especially true for neurodivergent children, who may experience:
- sensory overload
- anxiety or uncertainty
- communication differences
- fatigue or burnout
- challenges with emotional regulation
What may appear as refusal, anger, withdrawal or shutdown is often a signal that a child’s nervous system is overwhelmed.
For example, a child who leaves the classroom or refuses a task may be responding to:
- sensory overload
- fear of failure
- anxiety about social judgement
- understanding instructions
- exhaustion from masking or concentrating
Understanding behaviour as a form of communication allows adults to shift away from behavioural management techniques and toward curiosity, support and problem-solving.
Strategies to support behaviour as communication:
- Pause and get curious rather than reacting immediately; ask yourself, “What is this behaviour telling me?” before deciding how to respond.
- Look beneath the behaviour to identify possible unmet needs such as sensory overload, anxiety, fatigue, or confusion.
- Validate the child’s experience, even if the behaviour is difficult, e.g. “That felt really hard for you.”
- Focus on co-regulation first by staying calm, using a gentle tone, and offering your presence rather than trying to reason in the moment.
- Reduce demands temporarily when a child is overwhelmed, as continuing to push can increase distress and shutdown.
- Offer simple choices to restore a sense of control, such as “Do you want to try this now or in five minutes?”
- Use clear, simple language and break tasks into smaller steps to reduce cognitive and emotional load.
- Notice patterns over time to understand triggers and plan ahead for known challenges.
- After the moment has passed, reflect together (when the child is calm) to build understanding and problem-solve for next time.
The nervous system and stress responses
Human beings are biologically wired to respond to perceived threat as a form of self-protection. These responses are automatic and occur within the nervous system.
There are four common survival responses:
These responses are protective responses triggered when the brain perceives danger or overwhelm.
In neurodivergent children, sensory stress, social misunderstanding or cognitive overload can trigger these responses more easily.
The Window of Tolerance
Psychiatrist Dan Siegel describes the concept of the Window of Tolerance, which refers to the emotional zone where a person feels calm enough to think, learn and interact.
When children are within this window they can:
Supporting children to return to their window of tolerance is one of the most important ways adults can support emotional wellbeing.
Strategies to support a young person to remain within ‘The Window of Tolerance’:
- Be proactive rather than reactive – build regular regulation into the day, try to notice what keeps the child calm and engaged and keep demands at a level the child can realistically manage.
- Recognise early signs of dysregulation – learn the child’s cues (e.g. restlessness, withdrawal, irritability), respond early with small adjustments and gently check in throughout the day.
- Try to co-regulate first – stay calm, use a steady voice and slow your own pace, be physically and emotionally available without overwhelming them and focus on connection over correction.
- Offer simple regulation tools – encourage movement, provide calming input (a quiet space, reduced noise, dim lighting), use grounding strategies such as deep breathing, holding something familiar or sensory tools.
- Support return to regulation – offer small, low-demand choices (e.g. sit here quietly or take a short break), use familiar routines to help the child feel safe again, stay nearby until they feel more settled.
- Build skills when calm – teach children to recognise how their body feels when regulated vs overwhelmed, practise strategies outside of the stressful moments and help them to develop ways to ask for help or a break.
Counter-will and resistance
Doctor and trauma specialist Gabor Maté describes a concept called counter-will.
Counter-will refers to a natural psychological resistance that occurs when a child feels controlled, pressured or unsafe.
For some neurodivergent children, especially those with ADHD or demand-avoidant profiles, strong resistance to demands may be a self-protective response.
When children feel their autonomy is threatened, their nervous system may react with:
- refusal
- avoidance
- anger
- shutdown
This often means the child does not feel safe, understood or in control of a situation.
Reducing pressure, offering choices and maintaining respectful communication can help reduce these defensive responses.
Respectful communication examples:
- Acknowledge and validate first e.g. “I can see this feels really hard right now.”
- Reduce pressure in your wording e.g. “You’re not in trouble; I just want to understand.”
- Offer choice and autonomy e.g. “Do you want to do this at the table or on the floor?”
- Support breaks without shame e.g. “Do you need a break or some quiet time?”
- Keep connection at the centre e.g. “I’m here with you; we will work it out together.”
This kind of communication lowers a child’s sense of threat, supports their need for autonomy and keeps the adult-child relationship strong. Even during moments of resistance.
