Potty training is generally considered late if a healthy, developing child (without underlying issues) is still in diapers after age 3 or 4, especially after several months of consistent training efforts, showing no significant progress, or having strong resistance like fear or withholding stool, notes Banner Health, Mayo Clinic, and Mckenzie Pediatrics. While readiness varies, being over 3 with no interest or frequent accidents after trying for months suggests a delay, prompting consultation with a healthcare professional.

Americans potty train later due to the rise of convenient, absorbent disposable diapers, a cultural shift towards child-led, readiness-based parenting (focusing on the child's cues rather than parental convenience), increased maternal workforce participation, and daycare limitations, all of which contrast with earlier, cloth-diaper-era methods. The focus moved from quick training for parental ease to respecting the child's developmental milestones, often delaying the process until age three or later.
