Potty training readiness depends on physical, cognitive, and emotional development — not just age.
Average potty training ages:
- Earliest readiness signs: 18–24 months
- Most children start: 24–30 months
- Average completion: 27–36 months
- Nighttime dryness: 3–5 years (often later)
Key readiness signs (this calculator checks):
- Stays dry for 2+ hours at a time
- Shows awareness of wet/dirty diaper
- Can follow simple 2-step instructions
- Shows interest in the toilet/potty
- Can pull pants up and down
- Has regular, predictable bowel movements
- Tells you when going or about to go
- Can sit still for 2–3 minutes
Important: Readiness matters more than age. Starting before a child is ready often leads to longer training times and frustration. Most pediatricians recommend waiting for at least 5–6 readiness signs.
