Diaper Cost Planning Guide
Diapers are one of the most consistent recurring costs during a baby's first 2–3 years. Newborns require the most changes per day, gradually decreasing as they grow. Potty training typically completes between ages 2 and 3, marking the end of diaper expenses.
Buying diapers in bulk (box quantities) and using subscription delivery services can reduce the per-diaper cost significantly. Store-brand diapers often perform comparably to premium brands for everyday use.

- 12–18 months: ~5 changes/day

Over the long term, yes. Initial cloth diaper sets cost ₩100,000–300,000, but total costs can be 70–80% lower than disposables over 2–3 years. However, they require additional time for washing and drying.
Diaper sizes are based on baby weight: NB (newborn, up to 5kg), S (4–8kg), M (6–11kg), L (9–14kg), XL (12kg+). Too tight or too loose increases the chance of leaks.
