In a world where children are increasingly expected to fit neat behavioural and academic boxes, ADHD remains one of the most misunderstood and mislabelled neurodevelopmental conditions. For families navigating big emotions, school struggles and daily overwhelm, the gap between awareness and genuine support can still feel vast.
Few people understand this terrain better than Sue O’Callaghan, founder of Teenage Toolbox. With more than 35 years of experience working across schools, corrections and clinical settings, Sue brings a rare depth of insight to the conversation around ADHD, trauma and behaviour. As both a therapist and trauma‑responsive educator, her work centres on understanding why children behave the way they do, rather than simply trying to control it. Sue shares her perspective on ADHD in children, offering clarity, compassion and practical guidance for parents who may feel exhausted, confused or out of options. Her approach reframes ADHD not as a deficit, but as a different way of experiencing the world; one that needs informed support, not judgment.
Liz Cannon: Your career spans more than three decades across schools, corrections and clinical practice. What first drew you to working with children and families affected by ADHD?
Sue O’Callaghan: I was drawn to this work through a deep curiosity about how children experience the world, and why some struggle within systems not designed for them. Having worked in UK prisons, I saw firsthand how many individuals with ADHD slipped through the system without ever being given the tools to regulate, understand their physiology, or manage challenges like emotional outbursts and attention difficulties. Combined with my years living in boarding schools, where I saw diagnoses without meaningful support, it shaped my commitment to helping families move beyond labels toward strategies that reduce shame and build resilience. Hence, Teenage Toolbox was founded in 2013.
ADHD is often misunderstood or oversimplified. From your experience, what do parents most commonly get wrong, and what do you wish they understood sooner?
Common misunderstandings are:
– ‘ADHD is a behaviour problem’. By contrast, it is a regulation/communication tool and a neurological difference.
– ‘Children can naturally self‑regulate’. No child is born with the ability to do so in the absence of co‑regulation.
– ‘High‑sensitivity (HS) is a hindrance and struggle’. In an ADHD‑responsive environment, HS can bring out strengths like deep connection, creativity and innovative thinking. With the right support, traits such as curiosity, drive and individuation can produce brilliant entrepreneurs.
Your work is deeply trauma‑informed. How does trauma intersect with ADHD in children?
The word trauma relates to the dysregulation that happens inside us when we are under threat. ADHD and trauma are deeply intertwined because both impact a child’s ability to regulate their emotions, attention and nervous system. What can often look like ‘classic ADHD behaviours’ may be heightened by a child’s stress response, especially if they have felt unsafe or misunderstood. Without a trauma‑informed lens, we risk reinforcing shame rather than building safety, regulation and trust.
Through Teenage Toolbox, you focus on practical strategies. Can you share one or two tools that can make an immediate difference in family life?
At Teenage Toolbox, the focus is always on simple, practical tools. One of the most effective is helping children and parents understand the nervous system, using shared language to recognise and regulate what is happening in the body. Another powerful shift is moving from correction to connection. When a child feels safe and understood first, they are far more able to cooperate and engage. These small, consistent changes can transform the tone of family life very quickly.
With growing awareness around neurodiversity, what gives you hope for the future?
The greatest hope I see is coming through education. Trauma‑responsive programmes in schools and parent education are creating a shift, with more families seeking understanding rather than blame. It is encouraging to see schools developing child‑specific strategies for neurodiversity, including personalised psychological safety plans. As environments prioritise connection, co‑regulation, compassion and collaboration, the potential for a truly ADHD‑responsive society becomes increasingly real.
Sue invites parents to re‑frame ADHD not as behaviour to be managed, but as communication from a nervous system under pressure. By shifting the focus from control to safety and connection, her work offers a powerful shift: one that can ease shame, restore confidence, and create calmer, more resilient family life.
ADHD: A disorder or a response?
How a nervous system lens changes behaviour, regulation and the conditions for learning
ADHD parenting is relentless. Emotional explosions, sensory overload, and ongoing conflict around routines, homework, meals and getting out the door often leave parents feeling, ‘I’m failing’ or ‘Nothing works with my child’. Life can become a cycle of warnings, sticker charts, delayed consequences, removing privileges, or ‘Go to your room and calm down’.
Over time, an ADHD child can dysregulate the whole household, eroding not only family wellbeing, but also a parent’s confidence, capacity and nervous system. But what if ADHD behaviour was viewed not as disorder, but as response? What if behaviour itself was not the problem, but the language of a nervous system trying to communicate something deeper? Seen through this lens, behaviour becomes communication. Tantrums signal overwhelm, refusal reflects incapacity from the state a child is in, aggression shows mobilising fight‑or‑flight energy, tears indicate overload and release, silliness can mask discomfort, running off expresses a need to escape, and shutting down is the nervous system going offline because it is simply too much.
When we understand behaviour this way, the question shifts. We stop asking, ‘How do I stop this?’ and start asking, ‘What is my child’s system trying to tell me, and what will help it feel safe enough to settle?’ These shifts help parents make S.E.N.S.E. of a child’s world.
S = Sat nav
Children need language to understand their inner world. Without it, they often move into shame: ‘I’m naughty’, ‘I’m too much’, ‘I always get it wrong’. Describing the nervous system as an internal sat nav or Google Maps helps children understand that their body is constantly scanning for safety or threat, asking, ‘Am I safe? Is this manageable?’ Many ADHD children are not choosing to misbehave; they are overwhelmed, flooded or unable to access the skills being demanded. Using a simple traffic‑light system helps children map their state: green for calm and connected, red for fight‑or‑flight, and orange for freeze. When a child can say, ‘My sat nav is telling me this is too much’, shame gives way to self‑awareness, and with awareness come tools.
E = EV charger
Children cannot self‑regulate until they have experienced co‑regulation. A dysregulated child cannot simply be told to calm down, because their thinking brain is not fully online. They need to borrow calm first. Like an electric car moving through a demanding day, they need somewhere safe to plug in. That charger is often the parent, through tone of voice, pace, breathing, facial expression, touch and presence. Children learn regulation in relationship, not isolation. They borrow calm before they can build it themselves.
N = Navigating the senses
Like a zebra sensing threat, a child’s nervous system shifts state through the senses. Sounds, smells, textures, looks, unpredictability or criticism can rapidly move an ADHD child into protection. Once survival is priority, listening, learning, and flexibility become harder; not due to unwillingness, but because safety has been compromised. The same senses that trigger threat can also bring safety. Simple, intentional sensory supports like pleasurable touch, sound, smell, sight, taste, rhythm and predictability help bring the system back into regulation.
S = Stress response completion
Sometimes behaviour reflects unfinished survival energy. Children often prepare to run, shout, push or defend, but are required to stay still and compliant. The energy does not disappear; it lives on in restlessness, fidgeting, silliness, aggression or crashing. Safe physical outlets like movement, bouncing, shaking, dancing or rough play allow the body to finish what it started. What looks like hyperactivity is often energy that never got to complete its job.
E = Emotional safety plan
Rather than focusing on consequence and compliance, a nervous system approach asks what helps a child feel safe enough to return to regulation. An emotional safety plan identifies safe people, places, routines, sensory tools and exit strategies for moments of overwhelm. Especially during transitions, school changes or stressful situations, a shared safety map creates a platform of safety to prevent dysregulation, rather than a rescue remedy after.
When safety comes first, when children understand their inner sat nav, can borrow calm, are supported through their senses, allowed to complete stress responses, and have clear pathways back to safety, behaviour no longer has to speak so loudly. What emerges instead is more calm, more connection, more confidence, and greater capacity to learn. Not because the child is better managed, but because their nervous system no longer has to work so hard just to get through the day.
