I know the pressure is building. The preschool enrollment form has a line that says "must be potty trained." Your mother keeps casually mentioning that you were trained by 18 months (you were not, but she has convinced herself). Your friend's kid, who is three months younger than yours, is already wearing big kid underwear and your friend will not stop talking about it. The comparison trap is real, the timeline anxiety is real, and the temptation to just start training whether your kid is ready or not is very, very real.
But here is what I learned the hard way, after one failed attempt that set us back months and one successful attempt that went relatively smoothly: timing is everything. Starting before your child is ready does not get you to the finish line faster. It gets you to the frustration line faster. It creates power struggles, negative associations with the potty, and a whole lot of unnecessary laundry. Starting when your child IS ready? That is when the magic happens.
So how do you know when they are ready? Here are ten signs to look for, and what each one actually means.
1. They Stay Dry for Longer Stretches
If you are changing a wet diaper every thirty minutes, their bladder is not ready. But if you are noticing that their diaper stays dry for two hours or more at a time, that is a sign that their bladder muscles are maturing and they are developing the ability to hold urine. This is a physical prerequisite, not a behavioral one. You cannot train a bladder that is not physiologically ready.
2. They Show Discomfort in a Wet or Dirty Diaper
When your child starts pulling at their diaper, fussing after they have gone, or asking to be changed, they are developing an awareness of the sensation of being wet or soiled and a preference for being dry. This is important because potty training depends on the child wanting to be dry. If they genuinely do not care whether their diaper is wet, they have very little motivation to change their behavior.
3. They Hide to Poop
This is one of the biggest readiness signs, and it is one that many parents do not recognize for what it is. If your child goes behind the couch, into a corner, or to another room when they need to poop, they are demonstrating two crucial things: they are aware of the sensation before it happens (not just after), and they understand the concept of privacy around elimination. That is huge. That awareness is exactly what they need to recognize the sensation and redirect it to the toilet.
4. They Show Interest in the Bathroom
Following you into the bathroom. Asking questions about what you are doing. Wanting to flush the toilet. Asking to sit on the big toilet or on their own little potty. Any curiosity about the bathroom and what happens there is a readiness sign. You can encourage this by letting them come in with you (privacy is a thing of the past once you have kids anyway), narrating what you are doing in simple terms, and letting them explore the potty in a low-pressure way.
5. They Can Pull Their Pants Up and Down
This one is practical. If your child cannot pull their pants and underwear down by themselves, they are going to need help every single time they need to go. That is not a dealbreaker, but it does add a layer of dependency that can slow the process down. If they can manage their own clothing, even clumsily, they are physically ready for the independence that potty training requires.
6. They Can Follow Simple Two-Step Instructions
"Go to the bathroom and sit on the potty." That is a two-step instruction. If your child can follow directions like that consistently, their comprehension and executive function skills are developed enough for the training process. If they cannot yet follow two-step instructions, the mechanics of potty training are going to be confusing for them.
7. They Tell You When They Have Gone (or Are Going)
Whether they say "I went pee pee" after the fact or grab themselves and say "pee!" as it is happening, any verbal communication about elimination is a strong readiness sign. It shows awareness, language ability, and a developing connection between the physical sensation and the ability to communicate about it. Even nonverbal cues count here. If your child consistently makes a certain face, grunts, or squats when they are going, they are showing awareness.
8. They Want to Do Things "By Myself"
The independence streak that drives you crazy in every other area of life? It is your best friend during potty training. A child who insists on putting on their own shoes, feeding themselves, and doing everything without help is a child who is developmentally primed for the independence of using the toilet. They want to be a big kid. The potty is a big kid thing. Lean into that motivation.
9. They Have Predictable Bowel Movements
If your child poops at roughly the same time every day (after breakfast, after nap, whatever their pattern is), that predictability gives you a huge advantage. You can start by just sitting them on the potty at that time, casually, with no pressure. If they happen to go, it is a natural reinforcement of the toilet-elimination connection. Predictability makes the training process more manageable for everyone.
10. They Show Interest in Big Kid Underwear
If they are pointing at underwear in the store, asking to wear it, or excited about the idea of wearing underwear "like mommy and daddy," they are mentally ready to see themselves as a toilet-using person. This psychological readiness matters. A child who wants to wear underwear is a child who has already started thinking of themselves as someone who uses the potty. That mental shift is half the battle.
What If You See Some Signs But Not Others?
You do not need all ten. Most experts say that if you are seeing five or six of these signs, your child is likely ready for at least an introduction to the process. You might start casually, with a potty available and some low-pressure practice, and see how they respond. If they are engaged, great. If they are resistant, they might need a few more weeks or months.
The Signs They Are Definitely NOT Ready
On the flip side, if your child screams or cries when you mention the potty, if they have zero interest in the bathroom, if they cannot stay dry for more than 20 minutes, if they are in the middle of a major life transition (new sibling, new house, starting daycare), or if they are under 18 months old, pump the brakes. There is no prize for training early. There is no award ceremony. There is no developmental advantage to being trained at two versus three. The only thing that matters is that the process is relatively positive, relatively smooth, and completed without trauma for the child or the parent.
Trust Your Kid
At the end of the day, your child will tell you when they are ready. Maybe not with words, but with all these little signals that say "my brain and my body are prepared for this." Your job is to watch, listen, and respond. Not to force a timeline that works for preschool enrollment or grandparent expectations or Instagram comparison.
When the timing is right, potty training does not have to be a battle. It can actually be (dare I say it) kind of fun. You will celebrate pee with more enthusiasm than you ever thought possible. You will high-five over poop. You will call your partner at work to report a successful toilet visit. And it will feel absolutely triumphant.
But only if you start when your kid is ready. Trust them. They will show you when it is time.
