Potty Training Regression in Autistic Kids: Why It Happens (and What to Do)

 So, you thought you’d cracked it. Your autistic child was happily using the potty, you were high-fiving yourself, and maybe even dared to whisper “we’ve done it!” to your partner.
And then… BAM. Out of nowhere, accidents. Puddles. Tears (yours and theirs). Welcome to the wonderful world of potty training regression.



First things first: you didn’t fail. Your child didn’t “forget” everything. Regression is actually really common — especially for autistic and sensory kids. Let’s dig into why it happens (spoiler: it’s not because you’re rubbish at parenting), and what you can do to get things back on track.


💡 Why Potty Training Regression Happens in Autistic Kids

  1. Sensory Overload
    Toilets are loud, bathrooms echo, the seat feels weird — sometimes kids just get overwhelmed again. Even if they managed it before, a change in environment can trigger resistance.

  2. Big Life Changes
    Starting school, moving house, new sibling, illness — any of these can rock the boat. Our kids thrive on routine, and big shifts can knock potty progress.

  3. Anxiety or Stress
    Autistic kids often express stress through behaviours like toileting changes. It’s not a “step back,” it’s their way of showing something feels too much.

  4. Medical Stuff
    Constipation, UTIs, or even tummy bugs can make toileting painful. After one painful experience, some kids avoid the potty altogether.


✅ What You Can Do About It

  • Stay Calm (Even If You’re Screaming Inside)
    Regression isn’t permanent. The calmer you are, the easier it is for your child to feel safe trying again.

  • Reintroduce Visual Supports
    Bring back reward charts, visuals, and trackers. Kids respond really well to reminders, especially when their world feels shaky.

  • Make the Potty a Positive Place Again
    Add sensory-friendly touches — fidget toys, weighted lap cushion, even bubbles in the bathroom. Small changes can help them relax.

  • Rule Out Medical Issues
    If regression is sudden or painful, check with a GP just to be safe. Sometimes the fix is as simple as easing constipation.

  • Take the Pressure Off
    Some kids just need a break. Going back to pull-ups for a while isn’t failing — it’s regrouping.


💜 Final Thoughts (and a Little Help)

Potty training regression in autistic kids is tough, but it’s not forever. Think of it as a pause, not a failure. Your child hasn’t forgotten — they just need extra reassurance, routine, and maybe a sticker chart or two.
