Potty training is the process of transitioning a child from diapers to independent toilet use β a milestone that unfolds across months of practice rather than days of willpower. The American Academy of Pediatrics and most child-development research recommend a child-readiness approach that prioritizes developmental cues over chronological age, typically between 18 and 36 months for daytime training. Nighttime dryness is a separate, largely biological milestone that routinely follows daytime training by months or years and cannot be "taught" in the same way. The single most important mental model: potty training is about teaching a child to recognize body signals and act on them independently β not about getting a child to go when told.

Table 1: Readiness Signs Before Starting
Physical and behavioral readiness signs are stronger predictors of success than a child's age. Starting before these signs appear typically lengthens total training time without benefit, while waiting for clear readiness β particularly the ability to stay dry for 1β2 hours and awareness of the urge β dramatically smooths the process.
| Sign | Example | Description |
|---|---|---|
Diaper still dry 90 minutes after last change | Shows the bladder can hold urine long enough for the child to sense the urge and reach a potty | |
Child goes behind the couch or into a corner to have a bowel movement | Demonstrates pre-evacuation awareness β the child knows a poop is coming before it happens, which is the core prerequisite for using the potty | |
Diaper consistently dry after a 1β2 hour nap | Indicates developing sphincter control during sleep, often a sign daytime training will go smoothly | |
Says "pee," "poop," or tugs at pants; signs "bathroom" | Child must be able to signal the need to go in some way β words, gestures, or sign language all count | |
Follows caregiver into bathroom, tries to flush toilet | Shows readiness to model adult behavior and reduces resistance to sitting on the potty |
