Introduction
Potty training has evolved profoundly in one generation. Prescriptive approaches — “at age 2, a child should be potty trained” — have been widely called into question. In 2026, recommendations focus on the child’s maturity rather than their chronological age. Tools have evolved as well: the grow-with-your-child 3-in-1 potty has become popular with many families. Here is the current state of knowledge and practice. For more information: how to choose a potty and when to start.
1. Current official recommendations
The French Society of Pediatrics (SFP) and pediatricians agree that:
- Daytime continence is acquired on average between 24 and 36 months, but 18 to 48 months is entirely normal
- Nighttime continence generally follows daytime continence by about 6 months, and before age 5, bedwetting is not considered pathological
- Sphincter control requires neurological maturity, which is not reached before 15–18 months — starting earlier does not speed up potty training
- Parental pressure is a risk factor for regression and resistance
The dominant pediatric approach in 2026 is to let the child take an active role: potty training should be initiated by the child (or in response to their signals), not imposed according to a parental schedule.
2. Infant Natural Hygiene (INH): a developing practice
It is still a minority practice in France, but it is growing. It involves observing a baby’s bodily signals and accompanying them to the toilet from the first few months. The goal is not early potty training, but maintaining communication about bodily needs. Pediatricians point out that this practice requires a very significant investment from parents.
3. The grow-with-your-child 3-in-1 potty: why it has become so popular
It follows the child’s development: first as a standalone potty, then as a toilet seat reducer with an integrated cushion, and finally as a nonslip step stool for climbing onto the toilet independently. This material progression naturally supports the child’s growing independence.
It avoids resistance associated with using a new toilet: the flushing noise, the sensation of emptiness, and the height. Gradually transitioning through the toilet seat reducer reduces this resistance.
It reduces the total cost: a 3-in-1 potty replaces the separate purchase of a potty, a toilet seat reducer, and a step stool. Our Treelys Grow-With-Your-Child 3-in-1 Baby Potty with a removable plush cushion, CE-, REACH-, and ASTM F963-certified: grow-with-your-child 3-in-1 baby potty
4. What parents are doing differently in 2026
Parents in 2026 are delaying the start of potty training more often. The reasons include:
- Better information about the necessary neurological maturity
- Higher-quality diapers, making the discomfort of being wet less immediate
- Complex daily routines (daycare, work)
- Daycare-home consistency: parents align themselves with the approach used by the childcare facility
The associated risk is that some children enter the first year of preschool (at age 3) without daytime continence. The goal remains to support the child in achieving daytime continence before age 3.
5. The most common mistakes in 2026
- Starting during a period of change (moving house, the birth of a sibling, starting daycare)
- Punishing accidents: counterproductive and likely to increase anxiety
- Comparing the child with others: normal variation ranges from 24 to 48 months
- Failing to seek advice in the event of prolonged regression (more than 4–6 weeks without an identifiable emotional cause): a pediatric consultation is recommended to rule out an organic cause (urinary tract infection, constipation)

Conclusion
In 2026, the pediatric consensus is clear: follow the child’s pace, respond to their signals, avoid pressure, and use suitable tools such as a grow-with-your-child 3-in-1 potty. Discover our Treelys Grow-With-Your-Child Baby Potty: grow-with-your-child 3-in-1 baby potty
