Why Potty Training Regression Happens in Sensory Kids (And Why It’s Not a Step Back)

 If your child was doing fine with potty training and then suddenly…

wasn’t?

Accidents.
Refusal.
Fear.
Total nope.

First things first — this is not a failure.
And it definitely doesn’t mean you’ve gone “back to square one”.

For sensory kids, potty training regression is often a nervous system response, not a skill issue.

And once you understand why it happens, everything feels a bit less terrifying.


If potty training has felt impossible from the start, this explains why traditional methods often fail sensory kids - Why Potty Training Fails Sensory Kids (And It’s Not Your Child)

Let’s Say This Clearly (Because Parents Need to Hear It)

Regression does not mean:

  • your child forgot how to use the toilet

  • they’re being lazy

  • you rushed them

  • you messed it all up

It usually means:
👉 something tipped their sensory or emotional load over the edge.

Potty skills are often the first thing to wobble when a sensory child feels overwhelmed.

Why Potty Training Regression Is So Common in Sensory Kids

🧠 1. The Nervous System Is Maxed Out

Sensory kids process everything more intensely.

So when life throws in:

  • illness

  • poor sleep

  • school changes

  • holidays

  • extra demands

  • emotional stress

…the nervous system goes into survival mode.

And when that happens?
Learning and body awareness take a back seat.

Potty training relies heavily on:

  • noticing internal signals

  • staying calm

  • tolerating sensations

All things that disappear when a child feels unsafe.

🔁 2. Potty Skills Aren’t “Hard-Wired” Yet

For many sensory kids, potty skills aren’t fully automatic.

They’re still being:

  • consciously managed

  • mentally monitored

  • emotionally tolerated

So when stress hits, those skills drop off first — not because they’re gone, but because the brain is prioritising safety.

Think of it like this:

The brain says, “We’ll come back to toileting later. Right now, we’re just surviving.”

🚽 3. The Bathroom Can Suddenly Feel Scary Again

Regression often shows up as:

  • fear of the toilet

  • refusal to sit

  • panic about flushing

  • accidents even when they just went

Sensory sensitivities don’t disappear — they fluctuate.

What was tolerable last month might feel overwhelming this week.

And no amount of “but you were fine before!” will change that.

⏳ 4. Pressure Makes Regression Stick Around Longer

This is the bit nobody tells parents.

When regression happens, adults panic.
We tighten the reins.
We push harder.
We bring out charts, timers, rewards, consequences.

For sensory kids, that pressure:

  • increases anxiety

  • reduces body awareness

  • makes accidents more likely

So the regression lasts longer — not because the child isn’t capable, but because they don’t feel safe.


This is also why reward charts and pressure often make regression last longer for sensory kids.  Why Reward Charts Don’t Work for Sensory Children

The Hard Truth (But Also the Reassuring One)

Sometimes the kindest thing to do is pause, not push.

That might look like:

  • going back to nappies temporarily

  • removing all pressure

  • focusing on regulation first

  • talking about the toilet without expectation

This isn’t “giving up”.

It’s letting the nervous system reset so skills can return.

And they usually do.

What Actually Helps During Potty Training Regression

This isn’t about starting again from scratch — it’s about supporting the wobble.

What helps sensory kids most:

  • calm, predictable routines

  • no commentary on accidents

  • neutral reactions

  • visual supports without rewards

  • reassurance that they’re safe

  • time (yes, boring but true)

Progress comes back when pressure drops.

If You’re Feeling Defeated, Read This Slowly

If regression has made you feel like:

  • all your hard work was wasted

  • you did it “wrong”

  • everyone else finds this easier

Please know this:

👉 Your child hasn’t lost skills.
👉 They’ve had a nervous system wobble.
👉 That’s not permanent.

Why I Created a Sensory-First Potty Training Guide


                                                                Available here!

I didn’t create it to:

  • rush children

  • force milestones

  • “fix” regression

I created it because sensory kids need:

  • predictability

  • safety

  • visuals over pressure

  • support through setbacks

It’s designed to work with regressions, not pretend they don’t happen.

Because real life doesn’t move in straight lines.

Final Thought (The One That Matters Most)

Potty training regression is not a step backwards.

It’s a signal.

And when we listen — instead of pushing through it —
kids find their way forward again, in their own time.

You’re not failing.
Your child isn’t broken.
You’re just navigating a nervous system that needs gentleness.
