Every child is unique, but our 3rd son Herbie has shown us just how different—and wonderful—communication can be when it’s grounded in understanding, patience, and compassion. Herbie has a diagnosis of Aurism and ADHD and has a PDA profile — a way of being in the world that means everyday demands can feel overwhelming, threatening, or impossible rather than simply annoying or inconvenient.
One of the biggest shifts in our family life has been learning what PDA actually is, and how something as simple as the words we use can make all the difference.

So What is PDA ? How is it for Herbie)?
Pathological Demand Avoidance (PDA) is a profile of autism characterised by extreme resistance to everyday demands and expectations — not because a child is defiant or “chooses not to comply,” but because their nervous system interprets demands as threats. The moment a demand is felt, it can trigger anxiety, overwhelm or shutdown. Even with percieved or silent demands.
Importantly, PDA has nothing to do with wilfulness or lack of discipline from ” weak parenting”. When someone like Herbie with a PDA profile avoids something — even something they genuinely want — their body and nervous system are reacting as if they’re under threat. This isn’t bad behaviour, it’s a nervous system response — a survival instinct, not a choice. ITS PAINFUL for him at times!
Dr Naomi Fisher, a clinical psychologist who works with children and adults with PDA, talks about this extensively. She explains that what looks like avoiding tasks, controlling behaviour, or saying “no” repeatedly is actually a logical response to anxiety. The more a child perceives control or pressure — even indirect pressure — the more their nervous system goes into survival mode, making demands feel intolerable.
In her words, PDA isn’t something to be “fixed”; it’s a profile that needs to be understood. For Herbie, this insight has transformed the way we parent, communicate, and support him.

What is Declarative Language — and Why It Matters

One of the most powerful tools we learned about on our PDA journey is declarative language.
🔹 Imperative language vs Declarative language
Imperative language is directive — it gives instructions, expectations, or demands. For a child with PDA, even gentle-sounding requests can feel like commands demanding compliance:
👉 “Put on your shoes.”
👉 “Time to brush your teeth.”
👉 “You have to get ready for bed now.”
Even when meant kindly, these can trigger anxiety, overwhelm, resistance or shutdown because they feel like pressure to comply.
Declarative language, on the other hand, shares information without asking for compliance. It invites awareness, reflection or choice, but doesn’t carry the psychological “threat” of a demand. Declarative language helps a child feel safe and competent rather than cornered.
📌 Examples of Declarative Language
Here are some real-world examples:
- Instead of: “Put your shoes on.”
Say: “Your shoes are right there next to the door.” - Instead of: “It’s time to brush your teeth.”
Say: “I’m going to brush my teeth now.”
(This shares what you are doing rather than telling them what to do.) - Instead of: “We need to leave in five minutes.”
Say: “The car will be here in about five minutes.” - Instead of: “Come and get your breakfast.”
Say: “Breakfast is on the table.”
Declarative language doesn’t demand anything — it shares something and this subtle shift can reduce pressure and give children like Herbie space to respond on their own terms.

Why This Works
When we use declarative language, we are:
✔ Reducing psychological pressure
✔ Increasing autonomy and safety
✔ Lessening defensive reactions
✔ Supporting regulation of the nervous system
For a child whose nervous system is highly sensitive to perceived demands, this can mean the difference between shutdown and engagement. This isn’t about permissiveness or letting a child “rule the house”; it’s about meeting them where they are neurobiologically.
Dr Naomi Fisher emphasises that behaviours like avoiding demands, withdrawing, negotiating or saying “no” are responses rooted in anxiety and survival, not behaviour that’s chosen or manipulative. When we understand that, everything changes.
What We’ve Learned from Herbie
Herbie has taught us that:
❤️ His resistance isn’t willful — it’s a nervous system response.
❤️ When he feels less pressured, he stays calmer, more engaged, and more willing to participate.
❤️ Using declarative language doesn’t magically make demands disappear — but it reduces the fight-or-flight reaction that used to turn every tiny request into a battle.
We don’t have perfect days. But understanding PDA through the lens of nervous system regulation, and communicating through declarative language, has brought trust, connection, and peace into our home.
Supporting a child with a PDA profile means rethinking what “communication” and “compliance” really mean. It’s not about parental control — it’s about love, connection, safety, and collaboration. When we let go of the notion that our children are being difficult on purpose, space opens up for understanding, confidence, and joy.
If you’re walking a similar path with your child, know this: the words we choose matter — not because they control behaviour, but because they shape experience.
