When potty training is not working — what’s actually going wrong and what to do next
You started with good intentions. You bought the potty, you talked it up, maybe you tried stickers. And then somewhere around day two or three — or maybe further in — it stopped working. Accidents everywhere. Your child refusing. You not knowing whether to push through or stop. The nappies quietly going back on.
If this is where you are, the first thing to know is that potty training failure is almost never about the child. It’s almost always about one of a small number of identifiable problems — with the timing, the approach, or the consistency. Most of them are fixable. This page will help you work out which one applies to you.
First: is it actually not working, or does it just feel that way?
Day 3 is the hardest day of potty training for almost every family. Progress from days 1 and 2 seems to plateau or reverse. Accidents increase. Your child may seem less interested than they were at the start. This pattern is so consistent that it has a name — the day 3 dip — and it’s the point where most parents conclude that potty training isn’t working and put the nappies back on.
Before you do anything else, ask: are we on day 3? If yes, the answer is almost always to carry on. The children who get through day 3 consistently emerge dry. The children whose parents stop on day 3 usually have to start the whole process again from scratch weeks later — and it’s harder the second time because the child has learned that stopping is an option.
If you’re past day 3 and things still aren’t improving, read on.
The most common reasons potty training stops working
1. Your child wasn’t quite ready when you started
Readiness is the most common cause of genuine potty training failure — and the hardest to admit once you’ve already committed to a week off and bought the supplies.
The signals to look for: can your child walk to the bathroom independently, communicate when their nappy is wet or dirty, follow a simple two-step instruction, and show some interest in what happens in the bathroom? If two or three of those weren’t clearly present when you started, the timing may simply have been slightly off.
This isn’t a character flaw in your child. Readiness develops on its own timeline. A child who isn’t ready at 22 months may be completely ready at 26. The approach that fails at the wrong moment often works smoothly a few weeks later.
What to do: stop, wait four to six weeks, and try again. Use the free readiness test before you restart to make sure the signals are actually there this time.
2. The approach wasn’t consistent enough
Inconsistency is the second most common cause. This includes:
- Putting the nappy back on for trips out, family visits, or “just this once”
- Switching between potty and toilet without a clear plan
- Different approaches from different caregivers (mum doing one thing, grandparents doing another)
- Rewarding some successes but not others
- Starting training but not being fully at home and present for the first three days
Children — especially toddlers — depend on predictability. When the rules feel unclear or changeable, they can’t learn them. The nappy going back on “just for the trip to Tesco” sends a message that the new arrangement isn’t actually permanent, which makes it much harder to convince them it is.
What to do: if inconsistency was the issue, a clean reset usually works. Treat it as day one again. Pick a week where you can be genuinely consistent — at home for the first three days, same approach from everyone involved — and follow through fully.
3. There’s no clear method — just winging it
A lot of potty training attempts fail not because the parent is doing something wrong, but because there’s no clear plan at all. They’ve read conflicting advice online, they’re not sure when to offer the potty vs. wait for their child to ask, they don’t know what to do when an accident happens, and they’re making it up as they go.
Improvising works for some children. But for many, especially those who are more sensitive or more stubborn, the lack of a clear structure means the training never quite takes hold. The child can sense that you’re uncertain — and uncertainty is not reassuring when you’re being asked to do something new and slightly frightening.
What to do: follow a structured method with a clear day-by-day plan. Know what you’re doing before you start, not just in general terms but specifically: what happens today, what you do when there’s an accident, what success looks like this afternoon.
4. Your child is refusing — and you’re turning it into a battle
Refusal is one of the most stressful situations in potty training because it can feel personal. Your child says no, you ask again, they say no louder, you feel your patience slipping, and suddenly you’re in a standoff that has nothing to do with the potty anymore.
Highly sensitive children are particularly prone to refusal when they feel pressured. But any toddler can dig their heels in if potty training starts to feel like something being done to them rather than something they’re doing themselves.
What to do: step back from the pressure entirely. Don’t ask “do you need the potty?” — say “will you tell me when you need to go?” and then wait. Make the potty a calm, familiar, positive place rather than a battleground. Read a book there together before it needs to be functional. The guide on potty training a highly sensitive child has more detail on handling refusal without escalating it.
5. Poo is the problem, not wee
Many children crack wee within a few days but hold on for poo — sometimes for days, asking for a nappy, hiding behind the sofa, or simply waiting until bedtime when the pull-up goes on. This is extremely common and almost always rooted in anxiety rather than defiance.
The sensation of pooing somewhere new feels unfamiliar and, to some children, alarming. They haven’t yet learned that the feeling they’re resisting is actually fine to release on the potty.
What to do: don’t refuse the nappy for a poo if your child asks — refusing tends to make the anxiety worse and can lead to withholding, which becomes a medical problem. Instead, accept it, keep praising wee success, and very gradually move the nappy closer to the potty over several days (nappy on in the bathroom, then sitting on the potty with the nappy on, then nappy off). Most children get there within two to three weeks of cracking wee.
6. Something changed mid-training
A new sibling. Starting nursery. Moving house. A holiday. An illness. Any significant change during or just after potty training can cause a child to regress — going back to accidents after being dry, or becoming suddenly resistant after cooperating well.
This is not failure. It’s a stress response, and it resolves once the child feels settled again. The training itself hasn’t been undone — the learning is still there.
What to do: don’t restart from scratch. Keep the pants on, lower the pressure, reintroduce the reward chart, and give it a week or two. In most cases, dryness returns without needing to repeat the whole training process. If it doesn’t settle within two to three weeks, a gentle structured reset usually works.
7. The rewards stopped working
The sticker chart was exciting for two days, then your child stopped caring. This happens when the reward feels too far away (too many boxes to fill before anything happens), when the same reward has been given too many times and lost its novelty, or when your enthusiasm as a parent has quietly dropped off.
What to do: start with the 3-box chart — a completed chart in the first morning, a celebration, and momentum established early. Then move to 5 boxes, 7, then 9 as confidence grows. The graduated structure keeps the challenge matched to your child’s growing ability. And remember: your reaction — a genuine, warm, over-the-top celebration — is more motivating than the sticker itself. Don’t underestimate what your enthusiasm does.
When to genuinely stop and wait
Stopping isn’t failure — stopping at the wrong moment and restarting four weeks later with a better approach is often the fastest route to success. Stop and wait if:
- The readiness signals genuinely weren’t there — walk, communicate, follow instructions, show interest
- A major life change is happening right now or is imminent (new baby, house move, starting nursery)
- Your child is unwell
- You don’t have the time or headspace to be consistently present for the next five to seven days
In all other cases, pushing through with a clear method is almost always better than stopping. Stopping teaches your child that stopping is an option — and that lesson is harder to undo than the original potty training challenge.
When to speak to a doctor
In a small number of cases, potty training difficulties have a physical cause. It’s worth speaking to your GP if:
- Your child is over 4 and showing no signs of readiness at all
- They seem to find weeing or pooing painful
- There’s blood in their urine or stool
- They were previously dry and have suddenly started wetting again without an obvious trigger
- They’re withholding poo to the point of discomfort or it’s been more than three or four days
These situations are uncommon, but they’re worth ruling out before assuming the issue is behavioural.
