The Toilet Training Mistake Most Aussie Parents Are Making (And How to Fix It)
Starting too early is just the beginning. Here is what child development research actually says works, and why most advice gets it wrong.
Everyone has an opinion on toilet training.
Your mother-in-law says start at 18 months. Your friend's kid was done by two. The internet has a three-day method that "always works." The mothers group WhatsApp thread has been going for three days about pull-ups versus underwear and nobody has agreed on anything.
The reality is that most toilet training advice is too rigid, starts too early, or comes from someone who has never dealt with a toddler having a full meltdown in the middle of Coles at 2pm on a Tuesday.
This guide is what we wish someone had given us before we started. It pulls together what child development research actually shows, what Australian parents have learned the hard way, and what genuinely helps from the first signs of readiness all the way through to staying dry overnight.
When to Start Toilet Training
The average age Australian children begin toilet training is somewhere between two and three. But the right time has nothing to do with age and everything to do with readiness.
Starting too early is the single most common mistake. Research from the Journal of Pediatric Urology found that children who begin training before they are developmentally ready take significantly longer to complete the process, have more accidents overall, and in some cases develop anxiety around toileting that follows them into school.
The pressure to start early usually comes from outside childcare enrolment policies, family opinions, seeing another child the same age already trained. None of these are good reasons to rush.
The signs that actually matter:
- Stays dry for two or more hours at a stretch
- Tells you, or clearly shows, before or after they go
- Shows curiosity about the toilet or interest in proper underwear
- Can follow a simple two or three step instruction
- Can pull their own pants up and down
- Has a reasonably predictable routine when it comes to poos
If most of those sound familiar, your child is ready. If fewer than half do, give it another four to six weeks and check again. It genuinely is not worth pushing.
"We started at 22 months because our first was trained by then. Eight months of battles. With our second we waited until she told us she was ready. Three weeks and she was done."

"The liner gives our boys peace of mind that accidents won't be noticed at kindy and he easily goes and swaps his undies quietly himself. I recommend Rudie to all my mum friends."
10x Pack Training Pants"These are honestly so cute and super practical. The material feels really soft and lightweight which is perfect for everyday wear!"
Toilet Training Underwear"They are so handy. Makes my life easier to deal with accidents. The grips on the bottom keep it from moving around and it's super lightweight too."

There is no single method that works for every child, but parents and researchers keep coming back to the same foundations.
Give it a week or two of low-pressure introduction before the actual training begins. Read a book about it. Let them come in with you. Make the toilet familiar before it becomes a task.
Four or five days where you have no major commitments and can stay close to home. Start on a long weekend if you can. Consistency in the first few days matters more than anything else.
Pull-ups send a confusing message. They look like underwear but work like a nappy, so children have no reason to change their behaviour. Most child development experts now recommend skipping pull-ups during waking hours entirely. Yes, there will be accidents. That is how they learn.
Toilet when they wake up, before meals, before you leave the house, before bed. Too many "do you need to go?" questions actually makes children resistant. A simple routine removes the negotiation.
A child who has an accident is not being difficult. They are learning the connection between physical sensation and action. Clean up matter-of-factly, change them, and move on. Any emotional reaction frustration, disappointment, even a look makes the next accident more likely.

Shop the rangeThe Gear That Actually Helps
We are Rudie Baby and we make training products, so we will be upfront about that. But we have written this guide because the same questions keep coming up, and the honest answer is that having the right gear in place does make a difference.
Not because it trains your child. It does not. But accidents are less stressful when you are set up for them, and your child is more confident when what they are wearing feels normal rather than padded.
Training underwear versus pull-ups
Pull-ups are essentially a nappy with a different name. They are useful overnight when you are not yet night training, but during the day they slow things down because children cannot feel the difference between wet and dry. That sensation is the feedback loop that makes training click.
Reusable training underwear has a thin absorbent layer that catches the first burst of an accident without it running straight down their legs but it is thin enough that the child still feels wet. That is the balance you want during the learning phase.
Certified organic cotton with a slim bamboo terry pad. Fits like normal underwear your child will not notice the difference but gives you a buffer during the learning phase.
What about the bed
Most children have night accidents for weeks or months after daytime training is sorted. A waterproof layer under the fitted sheet means a 2am accident is a quick sheet change rather than a mattress situation.
Goes directly on the mattress under your regular sheet. No plastic crinkle, no slipping. Washes exactly like normal linen.
The Three Mistakes Most Parents Make
Almost every difficult toilet training experience comes back to one of these three things.
Already covered above but worth saying again. There is no prize for early training. The fastest way to a trained child is waiting until they are genuinely ready, not pushing because of a date on the calendar.
When a child senses that their accidents are disappointing you, the anxiety makes the next accident more likely. Sticker charts and small celebrations are fine but keep the focus on trying, not on getting it right.
If you have committed to underwear during the day, commit. Switching back to pull-ups outside of specific situations like long travel or illness resets the process. Consistency is the biggest factor in how quickly it clicks.
Night Training Is a Separate Thing
Night dryness is controlled by a hormone called ADH that reduces urine production during sleep. It develops at different rates in different children and has nothing to do with how daytime training went.
The average age for reliable night dryness in Australian children is somewhere between three and a half and five. Bedwetting up to age seven is medically normal. If your child is dry during the day but still wet at night, that is not regression. It is just where they are developmentally.
What helps: lifting them for a wee before you go to bed works well for some families. Keeping a waterproof layer on the mattress is non-negotiable. Having a spare set of sheets and pyjamas within easy reach means a middle-of-the-night change takes five minutes instead of twenty.
Night training will happen on its own timeline. It is not something you can push.
Toilet Training and Childcare
Most Australian childcare centres and kindy programs need children to be toilet trained, or in active training, before they start. This creates real pressure for families because the enrolment date does not always line up with when a child is actually ready.
Talk to the centre early. Most educators have been through this hundreds of times and are more flexible than the enrolment forms suggest. Send at least four or five changes of clothes every day during the training period. Keep the approach at home and at childcare consistent same language, same routine, underwear during the day at both places.
And try not to let the enrolment date push you into starting before they are ready. A few extra weeks almost always saves months of back-and-forth later.
