Understanding PDA

There is a particular kind of “no” that doesn’t sound like defiance.

It sounds like panic wearing a superhero cape.

It looks like a child digging their heels into the carpet as if the floor might swallow them whole. It looks like shoes hurled across the hallway because someone dared to say, “Time to go.” It looks like charm one minute and chaos the next.

If you’ve met this “no,” you might have come across something called PDA — Pathological Demand Avoidance, more recently reframed by many as Persistent Drive for Autonomy.

And that second name? It changes everything.

What Is PDA?

PDA is understood as a profile within the autism spectrum. It describes children who experience an intense anxiety response to everyday demands — even demands they want to meet.

Not just:

· “Do your homework.”

· “Brush your teeth.”

· “Put your shoes on.”

But also:

· “Come have cake.”

· “Let’s open presents.”

· “Time for your favourite show.”

To a child with PDA, a demand can feel less like a request… and more like a trap door opening beneath their feet.

It isn’t naughtiness.It isn’t manipulation.It isn’t poor parenting.

It is a nervous system shouting, “I need control to feel safe.”

What Does PDA Look Like?

It can be surprisingly hard to spot.

Some children with PDA are:

· Highly verbal

· Socially interested

· Imaginative and role-play driven

· Extremely perceptive about others

They may use:

· Distraction (“Did you see that bird?!”)

· Negotiation (“Maybe later.”)

· Excuses (“My legs don’t work.”)

· Role-play (“The queen does not wear shoes.”)

· Humour or charm

· Sudden meltdowns

Avoidance is not laziness. It is strategy.

And when avoidance fails, the nervous system can tip into:

· Fight (aggression, yelling)

· Flight (running away, hiding)

· Freeze (shutting down)

· Fawn (pleasing, then exploding later)

What It Looks Like in Everyday Life

Let’s walk through a Tuesday morning.

You say, “Put your shoes on.”

Your child:

· Laughs.

· Crawls under the table.

· Tells you their feet are allergic to socks.

· Suddenly needs the toilet.

· Starts a philosophical debate about footwear.

· Melts into tears.

By 8:23am, you’re questioning your entire parenting existence.

But here’s what may be happening:

The demand triggered anxiety.Anxiety triggered loss of control.Loss of control triggered survival mode.

PDA children often:

· Resist routines (even ones they created).

· Struggle with transitions.

· Seem fine one moment and explosive the next.

· Thrive when they feel in charge.

· Collapse when they feel cornered.

It’s less about the task.It’s more about autonomy.

Why Traditional Behaviour Strategies Often Don’t Work

Sticker charts.Firm consequences.“Because I said so.”Clear boundaries delivered with confidence.

For many children, these are helpful.

For PDA children? They can escalate everything.

Because the more pressure applied, the more the nervous system hears:

“You are not safe.”

And pressure can be invisible:

· Tone of voice

· Eye contact

· Rushed energy

· Even praise can feel like expectation

This is why parents often say:

“Nothing works.”

It’s not that nothing works.It’s that we need a different lens.

Helpful Approaches for PDA

Think collaboration over control.

1. Lower the Demand (Without Lowering the Expectation)

Instead of:

“Put your shoes on.”

Try:

“I wonder which shoes want to come on an adventure today?”“Should we race the timer or walk like penguins to the door?”

Indirect language can reduce the nervous system alarm.

2. Offer Real Choices

Not:

“Shoes now or timeout.”

But:

“Shoes before or after you grab your hat?”

Autonomy is oxygen for these children.

3. Co-Regulate First

When dysregulated, logic doesn’t land.

Regulate:

· Slow your voice.

· Reduce eye contact.

· Sit beside rather than in front.

· Use humour gently.

Calm nervous systems talk.Threatened nervous systems react.

4. Reduce Visible Pressure

This may include:

· Flexible routines.

· Fewer verbal reminders.

· Visual supports that feel collaborative.

· Predictability without rigidity.

5. Protect the Relationship

Connection is the intervention.

When a child feels:

“You’re on my team.”

Demands feel less dangerous.

Who Can Help?

Support may come from:

· A speech pathologist (especially for language flexibility, social communication, emotional regulation).

· An occupational therapist (sensory processing and regulation strategies).

· A psychologist (anxiety support, parent coaching).

· A paediatrician (assessment and medical guidance).

Support works best when it is:

· Neurodiversity-affirming

· Anxiety-informed

· Collaborative with families

Final Thoughts

If we shift from:

“This child won’t.”

To:

“This child can’t right now.”

We move from power struggle to problem solving.

PDA is not a child being oppositional for sport.It is a child whose nervous system experiences everyday life as a series of cliffs.

And cliffs require safety ropes — not pushing.
