In a nutshell: From around 16 months, some children may use more noticeable gestures, movements, sounds, or first words related to elimination. They might go to a corner, pull at their pants or backup, point to the bathroom, or fetch a caregiver. Other children may continue to only express themselves during or after elimination. Age alone, therefore, does not make a behavior a reliable signal. What matters is whether a similar combination of behavior, situation, and elimination repeats itself in your child.
Perhaps you are currently experiencing one of these moments:
Your child suddenly becomes quiet in the middle of play. They walk to a specific spot. Tug at their pants. Look at you intently. Take your hand or say a word you've heard in a completely different context before.
And you ask yourself:
Is my child telling me right now that they need to relieve themselves?
From toddlerhood onwards, communication around elimination can indeed become more visible. A mobile child has more ways to communicate: they can come to you, point to something, go to a specific place, or request a familiar routine.
However, this development does not follow a fixed calendar. Not every child signals more clearly from 16 months onwards. A word like "pee" can come before elimination, during it – or only when the backup is already wet. Retreating, tugging at the diaper, and heading towards the bathroom can also have other reasons.
In this article, you will learn what elimination signals are possible from 16 months, how to distinguish personal patterns from coincidences, and how you can still start elimination communication calmly now.
What changes in elimination signals from 16 months?
The short answer is: For some children, communication around elimination becomes more active – for others, it remains subtle or variable.
In their second year of life, many children gradually expand their ability to express a need. They may be able to more confidently reach a familiar place, recognize simple routines, use gestures more purposefully, or use first words. At the same time, the desire to have a say often grows.
This can make a potential elimination signal more easily visible to parents. A brief pause might turn into walking to a corner. A general sound might become a recurring personal word. Passive cooperation might turn into a clear yes or no to the potty.
However, there is no documented developmental step that automatically begins at 16 months. Some children show noticeable signs earlier, some much later, and some show no timely recognizable signals at all before peeing. Language, walking, and interest in the bathroom do not, by themselves, prove bladder or bowel control.
If your child is currently between 12 and 16 months old, you can find a detailed description of the transition phase in the previous cluster article "Baby 12–16 Months: Better Understanding Signals During Elimination Communication".
For an overview of all age phases, see our pillar article "Elimination Communication for Babies: Recognizing Signals – Explained by Age".
What elimination signals can toddlers show?
Elimination signals are personal. The same behavior can mean something completely different for two children. The following observations can occur around pee or bowel movements, but are not yet proof alone:
- pausing in the middle of play or suddenly becoming very quiet
- going to a corner, behind furniture, or to a familiar place
- squeezing legs together, shifting weight, or restlessly walking back and forth
- pulling at pants, bodysuit, diaper, or backup
- placing hands in the diaper area
- making deliberate eye contact or coming to a caregiver
- taking your hand and leading you in a specific direction
- pointing to a potty, toilet, or bathroom
- using a recurring sound or personal word
- refusing to get dressed or wanting to take off the backup
- appearing focused, straining, or seeking quiet during a bowel movement
- drawing attention to a full or wet diaper after elimination
Some children clearly signal bowel movements, while peeing remains hardly predictable. Others have reliable times but no visible signal. And sometimes parents only realize in hindsight that a gesture regularly correlates with elimination.
You don't have to "find" anything on this list. It is an invitation to observe, not a checklist your child should fulfill.
Before, during, or after: What is your child really showing you?
For parents, it's not only important how a child communicates, but also when. Because not every sign comes early enough to make it to the potty in time.
A possible signal before elimination
Your child comes to you, pauses, changes their posture, goes to a familiar place, or uses a specific sound. If pee or a bowel movement repeatedly follows a brief offer, this can become a personal pattern.
A sign during elimination
Your child strains, becomes focused, squats, makes a sound, or only at this moment says "pee" or "poo". They may perceive what is happening, but cannot necessarily announce it beforehand or wait.
A communication after elimination
Your child touches the wet backup, brings a change of clothes, says a word, or leads you to the bathroom. This may indicate that they notice wetness, smell, or the completed process. It is valuable communication – but not yet a signal before elimination.
This distinction provides relief. Your child hasn't done anything "too late." And you haven't overlooked a signal if the information only came after pee or a bowel movement had already landed in the backup.
How to recognize a personal pattern instead of a lucky guess
A single glance or a random trip to the bathroom says little. An observation becomes more meaningful when several things fit together:
Behavior + Situation + Repetition + Elimination = possible personal signal.
These four questions help you to classify:
- What exactly is your child doing? First, describe only what is visible: "They pause and pull at their pants."
- In what context is it happening? After waking up, after a meal, in the middle of play, or only when a diaper is already wet?
- What happens shortly after? Does pee or a bowel movement actually come after a voluntary offer or a little later?
- Does the same combination repeat itself? Several similar situations are more helpful than a single hit.
Your interpretation can remain a hypothesis. Instead of "You have to pee," you can say: "You're pulling at your pants. Maybe you need to pee. The potty is here."
This way, you give your child an option without dictating what they should be feeling or doing.
Why pulling at the diaper, hiding, or "pee" don't always mean the same thing
Especially striking signs quickly lead to a clear explanation. However, toddler behavior often has several possible reasons.
- Tugging at the diaper: The backup can be wet, full, shifted, warm, or uncomfortable. Perhaps your child is simply preoccupied with the fastener.
- Going into a corner: Your child may be seeking quiet for a bowel movement. But they could also be playing there, observing something, or needing a moment alone.
- Saying "pee": The word can mean an urge to urinate, an ongoing elimination, a wet diaper, the potty, or the entire bathroom ritual.
- Running to the bathroom: Water, a mirror, an exciting object, or a familiar person might be waiting there.
- Becoming restless: Tiredness, hunger, a full stomach, a need for movement, a need for closeness, or overstimulation can look similar.
This does not mean that you cannot recognize signals. It only means: The context is more important than the individual gesture.
Is it too late to start elimination communication at 16 months?
No. You can also start with a toddler.
The beginning may look different than with a newborn. You observe not only body tension or brief restlessness, but can also include language, gestures, movements, routines, and small decisions.
Your child does not have to be potty-trained for this. They do not have to reliably recognize the urge to urinate, hold it, or be able to take off their pants independently. With elimination communication, you offer an alternative to eliminating into a diaper. This may initially only happen in one or two well-suited situations.
It is important not to make a race out of the later start. Your child does not have to "catch up." They are not learning for an exam, and the number of dry backups is not an assessment of your success.
If elimination communication is entirely new to you, our page "What is Elimination Communication?" explains the basics, the attitude, and a relaxed start.
A pressure-free start from 16 months in five steps
1. Choose a quiet anchor moment
Don't start with the most difficult time of day. Choose a transition that happens anyway – for example, after waking up or when opening the diaper. A single regular offer can be enough to start with.
2. Make the place and routine familiar
Show your child the potty or the safe toilet seat without expecting them to eliminate. Briefly state what the place is for. They can look, come along, and leave again.
3. Describe instead of questioning
Many questions in a row quickly create pressure – and a toddler may answer with "no" out of habit. A calm description is often easier: "We've opened the backup. You can sit on the potty for a moment now."
4. Keep the offer brief
If nothing comes or your child wants to get up, the attempt is over. Long sitting does not make a signal more likely. Put the backup back on and continue with your day.
5. Observe without a checklist of successes
Look back after a few days: Is there a situation that works calmly? Does your child show interest or rejection? Does a different place fit better? You are allowed to change the routine, pause, or stick to a single anchor moment.
Our free Mata Origin Start Guide accompanies you step by step if you want to learn about the attitude, signal sound, and suitable everyday situations.
What everyday situations can be helpful from 16 months?
You don't have to wait for signs all day. Recurring transitions can relieve you, especially if your child does not yet show a timely recognizable signal.
Possible anchor moments are:
- after waking up
- during morning or evening changing
- when opening or changing the backup
- before bathing
- before getting dressed to go outside
- after a long car ride or babywearing period
- after a meal, if your child remains relaxed
- before pajamas or the evening routine
An anchor moment is an opportunity, not a fixed potty time. Your child is allowed to do nothing, get up immediately, or not come along at all.
You can find more ideas in the article "Elimination Communication in Everyday Life: The Best Moments for Your Child".
Language, gestures and small choices
From 16 months, some children already understand short, familiar sentences. Others are more guided by tone of voice, gestures, and recurring routines. Both can help with elimination communication.
These formulations accompany without testing:
- "You're pausing right now."
- "Maybe pee is coming."
- "The potty is here."
- "Would you like to go to the potty or should I hold you?"
- "You don't want to. Then we'll get dressed again."
- "Your backup is wet. We'll change it."
- "You had a bowel movement. Your body worked."
Offer at most two genuine options that are both fine with you. A question like "Potty or toilet?" only helps if your child can also say no and leave the situation.
If your child uses their own sound or word, you can pick it up and combine it with your neutral family word. This creates understanding without your child having to use a specific term correctly.
If your child says no, runs away, or doesn't want to sit
More understanding doesn't automatically mean more cooperation. A child can know what the potty is for and still prefer to continue playing. They can show a possible signal and reject the offered position. They might have happily participated yesterday and clearly say no today.
A "no" is not regression and not an obstacle you have to overcome. It is an answer to the current situation.
End the offer if:
- Turning away or running away
- Stiffening or tensing the body
- Crying, fear, or clear protest
- Repeatedly getting up
- A clear verbal or non-verbal "no"
Holding them down, distracting, persuading, or waiting too long can turn elimination communication into a power struggle. A backup takes the pressure off: If your child doesn't want to right now, the elimination can land there.
If your child hides for a bowel movement
Some toddlers seek a quiet or secluded place for bowel movements. They become still, go behind furniture, stand in a corner, or don't want to be observed.
This can be a recurring hint around elimination. However, it is not automatically an invitation to quickly take the child to the potty. Perhaps the bowel movement is already underway. Perhaps your child needs privacy. Perhaps the familiar body posture, standing or squatting, is important at that moment.
You can calmly offer: "You want peace right now. The potty is here if you like." If your child declines, respect their retreat and remain available. After elimination, you can help with changing and neutrally state what happened.
Pay attention to the difference between withdrawal and withholding. Hard or pellet-like stools, pain, severe straining, traces of blood, a distended abdomen, or visible avoidance of bowel movements can indicate constipation. In such cases, your child needs a pediatric assessment, not more consistent potty offers.
Elimination communication is not the same as potty training or toilet training
A child can eliminate outside the diaper without being independently potty-trained. They can know a ritual without reliably announcing the urge to urinate in time. And they can be interested in the toilet without being able to manage all steps on their own yet.
With elimination communication, the caregiver continues to provide some support: they recognize a possible hint or use a suitable moment, open the clothing, offer a safe place, and help with positioning if needed.
Independent elimination autonomy involves several skills that do not all develop simultaneously: perceiving bodily sensations, understanding their meaning, reacting in time, managing the journey, handling clothing, and wanting to go to the toilet or potty.
The Federal Institute for Public Health points out that first signs of readiness for potty training usually increase during the second and third year of life, and early, insistent training does not accelerate the process. So you can support your child without making every signal a training goal.
Safely enabling independence
Many toddlers want to co-create routines. Perhaps your child brings the potty, helps open their pants, or wants to walk there themselves. You can enable this participation without assuming more than your child can safely do.
- Place the potty stably and non-slip on the floor.
- Stay right there and never leave your child unsupervised on a toilet or elevated surface.
- When using the toilet, use a secure seat and, if necessary, stable foot contact.
- Choose clothing that can be opened quickly and without complicated fasteners.
Independence can initially simply mean: your child shows, participates, helps briefly and decides. They don't have to do everything alone.
Practical clothing and a backup for toddler everyday life
If a signal is only visible for a short time, complicated undressing can make the moment more difficult. At the same time, clothing should allow movement and be able to be closed quickly after a "no".
An easy-to-open wool elimination communication diaper can simplify offerings and serve as a backup in between. It does not have to stay dry to fulfill its purpose.
Even a wet backup is not a step backward. It only means that this time the excretion ended up there – maybe there was no signal, maybe it was too late, maybe your child refused, or everyday life simply didn't allow for an offer.
We explain in detail how diapers and elimination communication go together in a relaxed way in the article "Elimination Communication with Backup: Why a Diaper is Not a Step Backward".
Elimination communication with daycare, childminder or other caregivers
Other caregivers don't need to fully understand your personal language immediately. A simple, realistic process is often more helpful than a long list of possible signals.
It's best to only share what has really worked for you:
- one or two recurring cues from your child
- a suitable anchor moment
- the word or gesture you use
- how clothing and backup are opened
- which safe position your child knows
- that a "no" is always respected
If elimination communication is not possible in childcare or if your child needs different routines there, it's okay to take a break. The same rules don't have to apply at home and in childcare. A backup provides security without all adults having to interpret every sign the same way.
What if your child doesn't signal at all after 16 months?
Then more intensive observation is not automatically the solution. Some children, even as toddlers, do not show any behavior before peeing that adults can reliably and timely recognize.
You can still:
- use one or two relaxed anchor moments
- only offer for bowel movements if a pattern is recognizable there
- continue to use a backup as a matter of course
- take a break and re-evaluate later
- only offer elimination communication if it remains easy for both of you
In the article "My baby doesn't signal anything at all - what to do with elimination communication?" you will find further options for a stress-free restart.
You can also read about why elimination signals do not follow a fixed developmental chart in "Do elimination signals change with age?".
When you should have complaints clarified by a pediatrician
A new word, fluctuating signals, or a temporary "no" to the potty are usually not a medical problem in themselves. Please seek pediatric advice if your child shows pain when urinating or having a bowel movement, blood is visible in the urine or stool, the urine appears unusually cloudy, or the frequency and amount of urination change significantly.
Also, hard, dry stool, repeated painful straining, visible withholding, a severely bloated or tense abdomen, fever, vomiting, unusual lethargy, or poor fluid intake should be medically evaluated.
Elimination communication can enable a comfortable elimination position. However, it does not replace a diagnosis or treatment for constipation, pain, or a possible urinary tract infection.
Frequently asked questions about elimination signals from 16 months
Do all children from 16 months onwards signal more clearly that they need to go?
No. Some children now use more noticeable gestures, ways, sounds or words. Others continue to signal pee barely noticeably or only during or after excretion. There is no fixed developmental step that begins at 16 months in all children.
Is pulling at the diaper a sign of pee?
It can be a hint, but it doesn't have to be. The backup may already be wet, full, shifted, or uncomfortable. Observe whether the pulling repeatedly occurs in a similar situation before an excretion.
Why does my child say "pee" when it's already happened?
Your child can perceive the ongoing process, the wetness, or the completed process, without being able to announce the urge to urinate in time beforehand. A communication during or after excretion is also communication.
Is it too late to start at 16 or 18 months?
No. Start with a calm anchor moment, a familiar place, and short voluntary offerings. Your child doesn't need to be potty trained, hold their pee, or open their clothes independently for this.
What do I do if my child hides for a bowel movement?
First, respect the desire for quiet and offer the potty without coercion. If your child refuses, do not take them out of their hiding place. For hard stools, pain, blood traces, or visible withholding, the pediatrician should be involved.
Is my child ready for potty training now?
An interest in the bathroom, a word, or a gesture does not yet prove all the skills for independent toilet use. Elimination communication can continue to be a supported offering. Potty training develops individually and is not accelerated by pressure.
What helps if my child always says no to the potty?
Accept the "no" and pause the offerings or limit them to a particularly calm transition. Also check whether the place, position, clothing, or frequent questioning have become uncomfortable. A backup can fully manage the situation.
Conclusion: From 16 months, your personal language can become more visible
From about 16 months, some children have more opportunities to actively communicate around elimination. They might pause, go to a specific place, touch their clothing, point to the bathroom, or use a personal sound.
However, no single behavior is automatically an elimination signal. Pay attention to the combination of behavior, situation, repetition, and actual elimination. Distinguish whether your child signals beforehand, comments on the ongoing process, or only reacts to a wet backup.
You can also start elimination communication now. Choose a few anchor moments, use calm language, keep offerings short, and respect every "no." Your child doesn't have to prove anything or catch up.
Perhaps your communication will become clearer. Perhaps it will remain volatile. Both are fine. Elimination communication can grow with your child – without potty pressure, without rigid age limits, and without the demand for perfection.
