En bref
Potty training tends to go best when it follows a child's readiness rather than a set age — some children are ready as young as 18 months, but most start between 2 and 4 years. Readiness is a mix of physical signs (staying dry in their diaper for several hours in a row, predictable bowel movements) and behavioural ones (interest in the toilet, being able to follow simple instructions, and telling you they need to go).

Points clés
- Potty training goes best when it follows readiness signs, not a fixed age: the Canadian Paediatric Society notes some children are ready as young as 18 months, but most start between 2 and 4 years.
- Look for physical signs (dry for several hours in a row, predictable bowel movements) and behavioural ones (interest in the toilet, following simple directions, telling you they need to go).
- Keep it low-pressure — pushing before a child is ready or reacting strongly to accidents tends to backfire. Regression around a big change like a new sibling is common and usually temporary.
The readiness signs
The Canadian Paediatric Society describes potty training as best started when a child shows readiness signs, not at a fixed birthday — some children are ready as young as 18 months, but most start between 2 and 4 years. Physical signs include being dry in their diaper for several hours in a row and having regular, predictable bowel movements. Developmental and behavioural signs include being able to walk to and sit on a potty, pull clothing up and down with help, follow simple directions, show interest in the toilet, and communicate the need to go.
A low-pressure approach
The same guidance emphasizes a relaxed, encouraging tone. Pushing before a child is ready, or reacting strongly to accidents, tends to backfire and can create power struggles. Praise for trying, matter-of-fact handling of accidents, and letting the child set some of the pace all help.
Markham's connection-first approach fits here: keeping it collaborative and pressure-free, rather than turning it into a battle, protects both the skill and the relationship.
When to talk to your provider
If training stalls badly, if there is significant constipation or withholding, or if you are worried about your child's development, your provider can help. Regression around a big change (a new sibling, a move) is common and usually temporary.
Les parents demandent aussi
What age should my child be potty trained?
There is no single right age. Some children are ready as young as 18 months, but most start between 2 and 4 years, and following the child's cues works better than a deadline.
My child was trained and started having accidents again — why?
Regression is common, especially around big changes like a new sibling or a move, and is usually temporary. If it is persistent or there is constipation or pain, check with your provider.
