Potty Training: When and How to Start
Key takeaways
- There's no fixed age to start — readiness signs typically appear somewhere between 18 months and 3 years.
- We started potty training at age 2, once she could stay dry for a couple of hours at a stretch.
- The first real progress for us wasn't announcing the need beforehand — it was telling us right after an accident, which came before advance warning did.
- Keeping her in nappies at first, alongside toilet attempts, actually helped her build the connection between the sensation and the need to go.
- Staying calm about accidents matters — anxiety around them tends to make toilet training harder, not easier.
Potty training felt like a milestone we weren’t sure how to time correctly — until real readiness signs made the decision fairly obvious.
When we started, and why
We began potty training when our daughter turned 2, once she was reliably staying dry for a couple of hours at a stretch — one of the clearer, more objective signs that she was physically ready, rather than picking an age just because other toddlers her age were being trained.
What actually happened, step by step
We told her clearly to let us know when she felt the need to go. To our surprise, the first real progress wasn’t advance warning at all — she started telling us right after an accident had already happened, before she was reliably announcing it beforehand. It took real time before she could consistently signal the need in advance rather than after the fact. We also kept her in nappies during this early stage rather than switching her out entirely right away, and that actually helped — wearing them while still attempting the toilet seemed to help her build the connection between the physical sensation and the actual need to go, rather than skipping that step.
What “ready” actually looks like
NHS guidance points to a similar readiness window — typically somewhere between 18 months and 3 years, with real signs to watch for rather than a fixed birthday to aim for: noticing when they’re urinating or need to go, being able to sit on and get up from a potty independently, and staying dry for an hour or two at a time. It’s also worth picking a period without other major disruptions — a house move, a new sibling, or starting nursery are all reasonable reasons to wait a little longer before beginning.
Handling setbacks calmly
Accidents are a normal, expected part of the process, not a sign that training has failed or that you started too early. Staying calm when they happen matters more than it might seem — visible frustration or anxiety around accidents tends to make the whole process harder, not easier, for a toddler who’s already navigating a new skill, following the same calm-over-punitive principle that applies to toddler behavior more broadly. If your toddler seems to actively resist using the toilet at some point, it can be worth backing off for a few weeks and trying again later, rather than pushing through resistance — much like holding off on other big changes during a difficult stretch tends to help more than pushing forward.
Potty training is also one of the developmental milestones with the widest normal range — comparing your own toddler’s pace to another child’s rarely helps and often adds unnecessary pressure.
Frequently asked questions
At what age should potty training actually start?
There’s no fixed age — readiness signs typically show up somewhere between 18 months and 3 years. It’s better to watch for real signs of readiness than to pick an age based on what other toddlers are doing.
What are the clearest signs a toddler is ready to start?
Noticing the need to go, being able to sit on and get off a potty independently, and staying dry for an hour or two at a stretch are all good practical indicators.
Is it normal for a toddler to report an accident after it happens rather than warning beforehand?
Yes — that was our own experience too. Advance warning tends to develop after the after-the-fact reporting stage, not before it, and both are genuine steps in the same direction.
Does keeping a toddler in nappies during early potty training attempts slow things down?
Not necessarily — for us, it actually helped her connect the physical sensation to the need to go, rather than skipping that step entirely.
What should I do if my toddler seems to resist potty training altogether?
Stay calm rather than pushing through the resistance, and consider backing off for a few weeks before trying again. Forcing it during active resistance tends to make the process harder rather than faster.
