Potty training: a key moment, not a race
Potty training is one of the major milestones in a child's development. And yet, it is often approached from the perspective of performance – 'at what age?', 'how to do it quickly?' – rather than from that of physiological maturity and confidence. Before even choosing a potty, it is useful to understand what developmental neuroscience teaches us: a child cannot control their sphincters until the necessary neurological connections are established. This process rarely occurs before 18 months, often between 24 and 36 months, and varies from child to child.
The role of the potty is therefore not to accelerate this maturity. It is to support the child when it is there.
When to start: signs to look for
Rather than setting a date on the calendar, pediatricians and Montessori educators agree on an observation-based approach. A child is ready to explore the potty when they show several simultaneous signals:
Physiological signs
The diaper remains dry for at least two consecutive hours, indicating sufficient retention capacity. The child is able to sit down and stand up unassisted. They begin to distinguish between being wet and being dry, and show discomfort with soiled diapers.
Behavioral signs
The child shows interest in adult toilets or those of other children. They announce – sometimes after the fact initially – that they have peed or pooped. They try to imitate the behaviors of the people around them. These signs should not be confused with simple fleeting curiosity: it is their regularity that counts.
Choosing a potty: the criteria that really matter
The childcare market offers dozens of potty models. Between musical versions, over-decorated designs, and superfluous accessories, it's easy to miss what really matters: safety, ergonomics, and adaptability.
Stability and ergonomics
A child sitting on a potty must feel secure. Their feet should touch the floor or a support, allowing them to push without effort and without fear of tipping over. A potty that is too high or too narrow can discourage the child and create a negative association with potty training. The shape of the seat must also respect the child's anatomy: a cushion or an ergonomic seat reduces pressure and makes the position sustainable over time.
Material and chemical safety
This is an often-neglected point. Cheap potties are sometimes made from plastics containing endocrine disruptors such as phthalates or BPA. However, the child is in direct and prolonged contact with the potty – through the skin, but also through the hands they then put in their mouth. It is essential to ensure that the product complies with REACH standards and is free of concerning substances. CE certifications and independent material tests are reliable indicators. To delve deeper into this topic, our guide on chemical safety of baby products details the substances to avoid and how to spot them on a product sheet.
Potty adaptability
A good potty is not a single-use item. In a mindful consumption logic – and to avoid accumulating products used for three months and then abandoned – it is relevant to choose a model that evolves with the child. Some potties transform into toilet reducers for the transition to adult toilets, then into a step stool to allow the child to access the toilet or sink alone. This type of 3-in-1 product addresses several stages of development with a single object, which is both more economical and more consistent with an anti-overconsumption approach.
This is precisely the approach of the Treelys 3-in-1 baby potty, designed to accompany the child from initial learning to complete toilet independence, with a comfortable EVA cushion that respects the child's posture and sensitivity.
Common mistakes to avoid
Starting too early
Offering the potty to a child who is not physiologically ready does not accelerate potty training – it can instead generate anxiety around the moment and delay acquisition. Pressure, even gentle, is counterproductive. The child's brain cannot be 'trained' to control functions that are not yet under voluntary control.
Making the potty an emotional issue
Over-praising successes or showing disappointment at accidents creates an emotional burden around a process that should remain neutral and natural. The child must learn to recognize their own bodily sensations – not to perform for adults. A calm and factual attitude ('you peed, we'll change you') is more effective than rewards or reprimands.
Choosing a potty based on design alone
Animal-shaped potties with sounds and lights can seem attractive. But they often distract the child's attention from what they are feeling in their body. Potty training is a proprioceptive learning: the child must learn to identify an internal sensation. A simple, stable, and comfortable potty serves this purpose better than a toy disguised as a potty.
Potty or toilet reducer: which approach to choose?
Some parents prefer to go directly to adult toilets with an adapted reducer. This approach, sometimes recommended in Montessori circles, has the advantage of accustoming the child directly to the format they will use throughout their life. However, it requires the child to be tall enough and comfortable moving to the toilet alone, which is not always the case at the beginning of training.
The potty often remains more accessible in the first few weeks, especially because it can be placed in the room where the child is playing, without delay. The transition to the toilet can then be made gradually, with a reducer, then a step stool. A 3-in-1 product precisely covers these three stages without multiplying purchases.
Integrating the potty into the daily routine
Potty training works best when it is part of a predictable routine. Offering the potty at regular times – upon waking, after meals, before bathing, before bed – allows the child to anticipate and pay attention to their bodily sensations at these specific moments. This is not conditioning: it is an aid to body awareness.
It is also useful to read about child development as a whole. Our article on evolving baby products places this type of choice in a broader logic: investing in items that last and adapt, rather than multiplying one-off purchases.
What to remember
Choosing a potty for training means first and foremost respecting your child's pace. It then means choosing a safe, ergonomic, and adaptable object – an object that supports learning without hindering it. The concrete criteria to remember: stability, certified material free of concerning substances, ergonomic seat, and the product's ability to evolve with the child's needs. The rest – color, design, accessories – is secondary.
