Potty Training Refusal: When Your Toddler Won’t Go (Including Poop Refusal)
Why toddlers refuse the potty — including the very common refusal to poop — and the calm, child-centred way through it, from a Canadian paediatric potty training consultant.
The short answer. Potty refusal is communication — it almost always has a reason underneath it, so the fix is to answer what it’s telling you, not to override it. For general refusal, take the pressure off completely, re-check readiness honestly, and consider a potty pause of a few weeks. For poop refusal — the most common kind — address constipation first so stools are soft and painless, put a footstool under your child’s feet so their knees come up above their hips, and if they’ll only poop in a pull-up, allow it and move it gradually closer to the potty at your child’s pace. Drop all pressure and never punish.

When “no” is the answer to everything
Few parts of potty training are as frustrating as flat refusal. Your toddler won’t sit on the potty. Or — the classic — they’ll happily pee on the potty but absolutely will not poop on it, holding out for a pull-up or holding it in entirely.
Refusal is one of the most common potty training challenges there is, and it almost always has a reason underneath it. Push against the refusal directly and it tends to harden. Find the reason and respond to that, and it usually melts.
This guide covers both kinds of refusal — general refusal, and the specific, very common poop refusal — and the calm way through each.
A quick note. This is general guidance, not medical advice. Poop refusal is frequently tied to constipation; if your child has hard or painful stools, please see Constipation and Withholding During Potty Training and speak with your healthcare provider. For potty training readiness overall, see our pillar guide, When Is Your Toddler Actually Ready to Potty Train?.
General refusal: when your toddler won’t engage at all
If your child refuses the potty across the board, the cause is usually one of these:
They’re not developmentally ready. This is the most common reason of all. Refusal is often a child accurately telling you their body and brain aren’t there yet. Readiness is a set of developmental signs, not an age — and pushing before those signs are present produces exactly this resistance.
It’s become a power struggle. Toddlers are wired to seek autonomy, and the potty is one of the few things fully under their control. The harder it’s pushed, the more refusal becomes the point.
A rushed or pressured start left a bad association. If potty training began with intensity, charts, or tension, the child may now associate the whole thing with stress and opt out.
Fear. The potty, the big toilet, the flush, the bathroom itself — any of these can be genuinely frightening to a small child.
How to handle general refusal
Take the pressure off — completely. Refusal feeds on pressure. Stop the prompting, the charts, and the tension.
Consider a potty pause. If refusal is entrenched, the most effective move is often to stop entirely for a few weeks. Put the pull-ups back on, drop the subject, and let everyone reset. This is not failure — it’s the single most reliable way to defuse a power struggle. When you return, do it calmly and with no fanfare.
Re-check readiness honestly. Run the readiness signs again. If several are missing, your child was right to refuse — and a few weeks will often change the picture.
Give your child ownership. Let them pick the potty, the underwear, the books. Choice reduces the power struggle.
Keep it low-key. Model it, read potty books, mention it lightly — but make it boring, not a campaign.
Poop refusal: the most common potty puzzle
Poop refusal deserves its own section, because it is extraordinarily common and has its own specific causes. A child who pees on the potty without complaint but will not poop on it is doing something very particular — and almost always for one of these reasons:
The withholding cycle. This is the big one. If a child once had a hard, painful poop, they can learn to associate pooping with pain — so they hold it in. But holding it in makes the next poop harder and more painful, which deepens the fear, which drives more holding. It becomes a self-feeding cycle, and it is the leading cause of poop refusal. This is constipation, and it needs to be addressed directly (see below).
The toilet feels unsafe. Pooping takes relaxation and a feeling of stability. A child perched on a big toilet with their legs dangling cannot get the position — or the security — they need. Many “poop refusers” simply don’t feel safe enough to let go.
Fear of the sensation. Some children find the feeling of a poop leaving their body strange or unsettling — and a pull-up, which holds everything close, feels more familiar and contained.
Control. As with general refusal, poop can become the thing a toddler holds onto, literally and figuratively.
How to handle poop refusal
Address constipation first. If your child’s poops are hard, large, or painful, the fear is rational — and no amount of encouragement will fix it until the poops are soft and comfortable. Soft, easy stools are the foundation; everything else is built on them. This usually means a conversation with your healthcare provider. (See Constipation and Withholding During Potty Training.)
Fix the toileting position. Put a sturdy footstool under your child’s feet so their knees come up above their hips — a squat-like position that physically helps the body relax and release. Use a child-sized seat insert so they’re not gripping the edge of a big toilet. This one change resolves a surprising amount of poop refusal.
Allow the pull-up — then move it, gradually. If your child will only poop in a pull-up, let them, with no shame. Then move in small, child-paced steps over days or weeks: poop in the pull-up, but in the bathroom; then standing next to the potty; then sitting on the potty with the pull-up on; and eventually without. Let your child set the pace. Each step is a win.
| Step | What it looks like |
|---|---|
| 1 | Poop in the pull-up, but in the bathroom |
| 2 | Poop in the pull-up, standing next to the potty |
| 3 | Poop sitting on the potty with the pull-up on |
| 4 | Poop on the potty without the pull-up |
Drop all pressure and never punish. Forcing, shaming, or punishing poop refusal makes the fear and the withholding worse. Calm, patient, and matter-of-fact wins every time.
The thread connecting both
Whether it’s general refusal or poop refusal, the underlying truth is the same: refusal is communication. A child refusing the potty is telling you they’re not ready, not comfortable, not safe-feeling, or not free enough from pressure. The fix is never to override the refusal — it’s to answer what it’s telling you.
When to see your healthcare provider
Speak with your provider if poop refusal comes with signs of constipation — hard, large, infrequent, or painful stools, or visible withholding — or with pain, blood, or tummy aches. Constipation behind poop refusal is common and very treatable, but it usually needs medical guidance to break the cycle. Persistent refusal that isn’t shifting despite a calm, low-pressure approach is also worth a conversation.
A note from me
Poop refusal is the potty challenge I get asked about most, and parents are often quietly worried their child is being deliberately difficult. They almost never are. Behind nearly every poop refusal I see is either a child who’s been frightened by a painful poop, or a child who simply can’t get comfortable and stable enough to relax. Both are solvable — and neither is solved by pressure. Soften the stools, steady the feet, drop the pressure, and let the child move at their pace. It works.
What to do this week
If it’s poop refusal: check whether your child is constipated, and put a footstool under their feet today. Those two moves address the two biggest causes. If it’s general refusal: take the pressure all the way off, and seriously consider a two-to-three-week potty pause. In both cases, the goal this week is the same — make the potty calm and low-stakes again.

Why does my toddler refuse to use the potty?
The most common reasons are that they’re not yet developmentally ready, that potty training has become a power struggle, that a rushed or pressured start created a bad association, or fear of the potty, toilet, or flush. Refusal is usually a child communicating one of these.
Why will my child pee on the potty but not poop?
Poop refusal is very common. The leading cause is the withholding cycle — a past painful poop leads to holding it in, which makes poops harder and the fear worse. Other causes are not feeling stable or safe on the toilet, and finding the sensation unfamiliar.
How do I get my toddler to poop on the potty?
Address constipation first so poops are soft and painless, add a footstool so their knees are above their hips, and if they’ll only poop in a pull-up, allow it and then move it gradually closer to the potty at the child’s pace. Drop all pressure and never punish.
Should I take a break from potty training if my child refuses?
Often, yes. A “potty pause” of a few weeks is the most reliable way to defuse a power struggle. Put pull-ups back on, drop the subject calmly, and restart later with no fanfare. It is a reset, not a failure.
When should I see a doctor about potty refusal?
See your healthcare provider if poop refusal comes with signs of constipation — hard, large, infrequent, or painful stools — or with pain or blood, or if refusal persists despite a calm, low-pressure approach.
