When to start potty training? Signs and tips are what most parents google when their child suddenly starts pointing at the potty, or when a friend's two-year-old is already diaper-free. The short answer: there's no magic age. There are, however, clear signs that your child is ready, and equally clear signs that you can wait a little longer. Here we walk through both, plus how to make the transition gentle on your child, their skin and your everyday life.
The short answer: when your child is ready, not when the calendar says so
Potty training isn't a race. Many children show the first signs somewhere between eighteen months and three years, but the range is wide and completely normal. A child who gets to start when they're ready usually learns faster and with fewer setbacks than a child who's pushed. So instead of counting months, watch your child. Body, mind and motivation tend to mature at roughly the same pace, and it's when all three are on board that things usually click.
Signs it might be time
You don't need to tick off everything on the list. But if you recognize several of these points, it's a good moment to start small.
The body is talking
- The diaper stays dry for longer stretches. Often a couple of hours at a time, or dry after a nap. That means the bladder is starting to hold more.
- Poos arrive at roughly the same time every day. A routine in the tummy makes the potty easier to time.
- Your child can walk, sit down and stand up on their own. Sounds obvious, but it's a must for making it to the potty in time.
- Your child can pull something simple down and up. Soft pants or a pant diaper count.
The mind is keeping up
- Your child notices when they pee or poo. Maybe they stop, go quiet, wander off or hide behind the sofa.
- Your child can tell you or show you that the diaper is wet, or that they need to pee. Words, gestures or a very determined look all work just as well.
- Your child understands simple two-step instructions, like "get the potty and sit down".
The motivation is there
- Your child wants to copy you. Follows you to the bathroom, wants to press the flush, asks for "big-kid underwear".
- Your child complains about the diaper. Tugs at it, wants it off, finds a wet diaper uncomfortable.
- Your child is curious about the potty and happily sits on it, even with clothes on.
Signs it's too early (and that's completely okay)
Waiting isn't failing. It's listening. Here are the signals that you can let it rest for a few weeks or months:
- Your child gets angry or scared as soon as the potty appears.
- The diaper is wet all the time, with no dry stretches.
- Your child doesn't react at all to a wet or full diaper.
- Life is in the middle of a big change. A new sibling, a move, starting daycare or illness. Potty training goes best in calm periods.
- It's you who wants it more than your child. That tends to show, and it tends to meet resistance.
If you've tried and hit a wall: pause without drama. Put the diaper back on, say "we'll try again later" and move on. Children often take giant leaps after a break.
Tips for a calm start
Once the signs are in place, the rest is about keeping it simple, safe and a little bit fun. Here's what usually works best:
- Let the potty move in early. Put it in the bathroom or living room a few weeks before you start. No pressure, just a new piece of furniture to get used to.
- Talk about what's happening. "You're doing a poo now" and "the diaper is wet now" help your child connect feeling to words.
- Offer the potty at set times. After breakfast, before the bath, after sleep. Routine beats reminders.
- Choose clothes that come off fast. Skip overalls, double snaps and bodysuits during potty training.
- Praise the effort, not just the result. Sitting on the potty is a win in itself.
- Expect accidents. They're part of learning, not a sign you've done something wrong.
- Tackle days first. Nights often come much later, and it's completely normal to need a night diaper long after the days are dry.
The pant diaper's role in potty training
Here's a simple trick many parents swear by: switch to pant diapers well before you start. A pant diaper works as a gentle stepping stone between diaper and underwear. Your child can pull it down and up themselves, just like real underwear. That gives them an "I can do it" feeling that's worth its weight in gold when the potty is there to be conquered.
At the same time, you get to skip mopping the floor every time the will is bigger than the bladder. Our pant diapers keep dry for up to 12 hours, so they handle both active days and the nights that still need protection. Against the skin is 100% bamboo, soft and breathable, with no lotion and no perfume. And they're made with significantly less plastic than many conventional diapers. Less plastic. More logic.
So the pant diaper isn't an obstacle to potty training. It's a tool. Your child gets to practice the movement, you get a little breathing room, and their skin gets left in peace during a period when it's getting plenty of attention anyway.
Which size fits a potty-training child?
Most children who start potty training land in one of our two largest sizes:
- The Kiddo Pant Diapers, 10 to 16 kg. Often the size for a child who's just started showing interest in the potty.
- The Explorer, 14 to 20 kg. For the biggest adventurers, and for the nights that need protection longer than the days.
A good tip from our size guide: pant diapers generally have a larger waist and leg opening than open diapers in the same weight class. If your child is between two sizes, go for the smaller one in pant diapers. Weight ranges are always a guide, and body shape plays a part. If you're unsure, there's a sample kit so you can test the fit before committing to a whole box.
Common questions about when to start potty training
Does my child need to be fully diaper-free during the day before we tackle nights?
No, but it's the most common approach. Days and nights are two different skills. Many children use a pant diaper or night diaper long after they manage dry days, and that's exactly how it should be.
We started, but things went backwards. Did we do something wrong?
No. Setbacks are common, especially with colds, travel or big changes. Pause, put the diaper back on and try again in a few weeks.
Can I change size during my subscription?
Yes. You can change size, pause or cancel whenever you like in your account. No commitment. Perfect for a period when your child is growing, both in body and in independence.
Next step: let the pant diaper do the work
Spotting several of the signs above? Then it's a good time to give your child a diaper they can pull up and down themselves. Start a pant diaper subscription in the right size, delivered to your door every month with free shipping. Pause when the potty takes over. Change size as your child grows. You're in charge.
Less leak, more sleep. Even during potty training.
