For many autistic and ADHD children and young people, behaviour can be a way of expressing a need, emotion, or difficulty that they do not yet have the words, energy, or skills to communicate in another way. When children and young people are overwhelmed, dysregulated, or struggling with executive functioning demands, their behaviour can provide important clues about what is happening beneath the surface.
By becoming curious about what a behaviour might be communicating, rather than focusing solely on stopping it, parents and carers can begin to better understand their child’s experience and respond in ways that support both their immediate needs and their long-term development.
Before we explore behaviour as a form of communication, it is important to consider what we mean by the word “behaviour”. Behaviour is simply anything a person does. It includes actions, reactions, body language, facial expressions, movement, speech, and even things that may appear passive, such as withdrawing, becoming quiet, or avoiding a situation.
Often when people talk about behaviour, they are referring to behaviours that are challenging, disruptive, or difficult to understand. However, behaviour itself is neither good nor bad. It is simply information about a person’s experience, needs, and environment.
Behaviour is sometimes treated as something to “fix” or stop, without considering what might be underneath it. However, behaviour does not happen in isolation.
Children and young people’s behaviour is influenced by a wide range of factors, including their sensory environment, emotional state, physical needs, communication differences, anxiety levels, previous experiences, and the demands being placed upon them. What we see on the surface is often the end point of a much longer internal process.
For example, a child refusing to get dressed may not be “being difficult”. They may be overwhelmed by the feel of their clothing, struggling with the transition from one activity to another, anxious about the day ahead, or finding it difficult to organise and sequence the tasks involved. The behaviour may look simple, but the reasons behind it are often much more complex.
Rather than focusing only on what a behaviour looks like, it can be helpful to consider what purpose it is serving in that moment. Behaviour can help a child or young person escape overwhelming demands, gain a sense of safety or predictability, seek or avoid sensory input, communicate distress, or cope with emotional overload. Understanding this function allows us to respond more effectively and compassionately.
Two children may show the same behaviour for completely different reasons. Equally, the same child may show different behaviours in response to the same underlying need depending on the situation they are in.
Many autistic and ADHD children and young people experience barriers in communication long before behaviour escalates. Some find it difficult to identify and describe what they are feeling, while others may struggle to access language when they are stressed or overwhelmed.
Processing delays, previous experiences of not feeling listened to, or difficulties recognising internal sensations can all make communication more challenging.
By the time behaviour becomes visible, the child or young person may already be well beyond their capacity to cope. What adults see as the beginning of a problem may actually be the final stage of a build-up that started much earlier.
This is why recognising early signs of dysregulation is so important. Changes in movement, tone of voice, energy levels, engagement, or withdrawal can all be indicators that a child or young person is finding things difficult. When these signs are noticed early, support can often be provided before distress escalates further.
Interpreting behaviour through a neuroaffirming lens means shifting the question from:
“What is this child or young person doing?”
to:
“What might this behaviour be telling us?”
This small shift changes the focus from control to understanding.
For example:
This does not mean every behaviour is acceptable or should be ignored. It simply means behaviour is understood in context before deciding how best to respond.
When a child or young person is dysregulated, they are often unable to access the skills needed to calm themselves, communicate effectively, or think through solutions. In these moments, many of their responses are being driven by their nervous system rather than conscious decision-making.
This is where co-regulation becomes essential. Before children and young people can learn to regulate independently, they first need repeated experiences of being supported by a calm and regulated adult.
Co-regulation may involve reducing the amount of language being used, lowering demands, offering physical or emotional space, validating feelings, and maintaining a calm, predictable presence. Often, it is less about saying the right thing and more about helping the child or young person feel safe enough for their nervous system to settle.
The goal is not to immediately correct the behaviour. Instead, it is to help the child or young person return to a state where communication, learning, and reflection become possible again.
A neuroaffirming approach does not mean that all behaviour is acceptable in every context, or that children and young people do not need guidance and boundaries.
Instead, it means:
Boundaries remain important. The difference is that they are applied with understanding, recognising that behaviour is often communicating something important.
When we begin to view behaviour as communication, we start to notice patterns that might otherwise be missed.
We may notice that certain environments consistently lead to distress, that particular demands trigger avoidance, or that sensory overload presents as emotional outbursts. We may see that transitions create anxiety or that fatigue reduces a child or young person’s ability to cope with everyday expectations.
This information is valuable. It allows parents, carers, and professionals to make changes that reduce distress and better support a child’s needs. Rather than repeatedly responding to behaviour after it happens, we can begin to understand and address the factors contributing to it in the first place.
Interpreting behaviour as communication is not about finding a perfect explanation for every action. It is about approaching autistic and ADHD children and young people with curiosity, compassion, and a willingness to understand their experience.
When children and young people feel understood rather than judged, they are more likely to feel safe, build trusting relationships, and develop the skills they need over time.
Behaviour is rarely random. It is information.
And when we learn to listen to what behaviour is telling us, we are better able to support autistic and ADHD children and young people in ways that truly meet their needs.
