About Diaper Costs

The average baby uses approximately 6,000-8,000 diapers before potty training, which typically begins around 24-36 months (we use 30 months as a midpoint). Costs vary significantly by brand, with premium eco-friendly options costing 2-3x more than store brands. Diaper usage naturally decreases as babies grow, from 10-12 per day for newborns down to 3-4 per day for toddlers.
