Is potty training under 2 years old possible? The short answer: YES! But it has far less to do with age and far more to do with readiness. Things like awareness of wetness, curiosity about the toilet, basic communication and a desire to ‘do it myself’ play a much bigger role.
We potty-trained Iliana at 21 months old, and while we’re still very much learning, she’s now able to initiate and occasionally use the potty on her own.
A quick note before we begin: This is not a how-to or comparison post. Every child develops at their own pace. There is no “behind” in potty training. This is simply my experience.
Iliana started showing interest in the toilet. Every time I went, she’d follow me in, quietly observe what I was doing and was especially fascinated by the flushing part 😂We also had been using the words “boo boo” and “shee shee” consistently since she was a baby, so she understood what they meant. On top of that, she could follow simple instructions, which gave me a bit more confidence starting potty training.
What she couldn’t do yet was recognize her own bodily cues. And I think modern diaper technology plays a big role here. These diapers are so absorbent it’s almost unreal. I once put Iliana in the pool with her diaper on and.. wow. The amount of water it absorbed was shocking. With that level of absorption, it’s no wonder toddlers don’t realize they’ve peed.
So, instead of waiting for bodily awareness to magically appear, we focused on helping Iliana notice it.
There’s no shortage of potty-training methods, each with its own philosophy — child-led approaches, elimination communication (EC), Oh crap! Potty training, the 3 day method… the list goes on. We decided to start with the Oh Crap! Potty Training method but modified it a little bit and moved through the training session in blocks based on progress rather than specific days. Below is the summary of the blocks for this method:
Block 1: Naked from the waist down
Block 2: Pants on, but no underwear
Block 3: Short Outings
Block 4: Underwear
Block 5: Self-initiation
Block 6: Nap and night training

Block 1 Oh Crap! Potty Training – Naked from the waist down
We stayed in this block for about five days, with the first three days requiring full, undivided attention. I watched Iliana like a hawk 😂If I needed to step away, I made sure our helper or my husband was fully tuned in and ready to step in. This stage involves plenty of accidents, with the focus on catching them in the moment and redirecting to the potty. While messy and tiring, it’s where understanding begins to shift from “I peed” to “I am peeing”.
Notes for Block 1

📝Naked from the waist down – No diapers, no pants
📝Gently intervene during accidents – Walk them to the potty while calmly saying “pee goes into the potty”. Keep it light and positive.
📝Offer the potty frequently – we did about every 30 minutes. Offer rather than ask.
📝Celebrate successes – Praise, claps or a little happy dance. Positive reinforcement matter.
📝Expect accidents, they’re part of the learning process, not a failure.
Block 2 Oh Crap! Potty Training – Pants on, but no underwear
We stayed in Block 2 for about a week. The transition from being naked from the waist down to wearing pants was a little inconsistent for Iliana. Having something wrapped around her bum seemed to trigger a sense of familiarity or “safety” and a few times that translated into accidents. Because of that, we had days where we went back to being pantless. We also stretched potty check-ins to about every 45 minutes. Here Iliana’s understanding begins to shift from “I am peeing” to “I need to pee” and have started initiating. One interesting observation during this stage was that Iliana was comfortable peeing in the potty but still reluctant to poop there. From what I’ve learned, this is actually quite common. Pooping requires a different level of physical and emotional comfort and many toddlers take longer to feel ready for it.
Notes for Block 2
📝No underwear, only pants
📝If accidents increase, go back to being naked from the waist down for a day or two. This isn’t regression! Many children move back and forth between blocks before settling.
📝Extend potty check-ins gradually.
📝Expect poop hesitation – it’s common.
Block 3 Oh Crap! Potty Training – Short Outings
We entered Block 3 about twelve days into potty training, once we had a better sense of Iliana’s patterns and timing. We could roughly anticipate when she’d need a potty check-in. For example, after meals or before screen time (yes, we do allow screen time in moderation). Because once Peppa Pig is on, she is not moving from the couch even if she’s sitting in a very obvious puddle of pee. And that’s kind of the point – once we learned her timing, we felt confident enough to start short outings. For us, that usually meant heading out for outdoor play in the evening, keeping it to an hour and staying close to home. These short outings helped Iliana practice holding it just a little longer.
Notes for Block 3
📝Short outings only, no underwear only pants
📝Offer the potty before heading out. This sets them up for success and reduce stress outside.
📝 Accidents are still part of the process! Stay calm, reassuring and positive. Confidence and calm from you help your child feel safe trying in new environments.
📝If they initiate outside, acknowledge and help them get to a potty as soon as possible.
Block 4 Oh Crap! Potty Training – Underwear (a detour)
We transitioned into “underwear” shortly after Block 3. This is where I made a small but important mistake. I bought Iliana training pants instead of regular underwear. My reasoning? She was already initiating, so surely she was aware enough, right?
Very wrong 😅
Training pants are thicker and more absorbent than regular underwear, which meant they felt far too similar to a diaper. That familiar sensation disrupted the learning loop. We had increased accidents and Iliana seemed less aware of what was happening. So we adjusted our approach and went back to pants only, which has been working well for her. We haven’t introduced underwear yet, and we’re comfortable staying here for now.
Notes for Block 4
📝 Underwear is typically introduced at this stage. We haven’t move forward with it yet – not out of resistance, but because Iliana has been doing well in pants. After mistakenly buying training pants earlier, we haven’t gotten around to purchasing proper underwear yet and we’ve been comfortable staying here for now.
📝 Opt for thin regular underwear. Not training pants or anything absorbent – we learned that those can feel too similar to diapers and disrupt awareness.
📝Even when introduced at the “right” time, underwear can trigger a temporary increase in accidents. Just keep being consistent with check ins or bounce between blocks until things settle again.
Block 5 Oh Crap! Potty Training – Self Initiation
Iliana began initiating earlier on, but it’s still very much a work in progress. Accidents still happen occasionally, especially when she’s tired or distracted but they no longer feel like setbacks. As I’m writing this, It’s been about 10 weeks since we started potty training and I do consider her potty trained — she’s gone many days without an accident, initiates on her own more often than not and understands where pee (and poop) should go. And honestly, we’re really proud of how far she’s come.

Block 6 Oh Crap! Potty Training – Nap & Night Training
We haven’t started this yet. Daytime training already feels like a huge milestone, so we’re not rushing the rest. Sleep matters more than dry sheets right now, and I’ll update this space once we get there.
