How many diapers does a baby use per day and per year?

Newborns (0–1 month) use 8–12 diapers per day; by 6 months this drops to 6–8; and by 12 months to 4–6. Over the full diapering period (birth to potty training at roughly 2.5–3 years), most children use 5,000–6,000 diapers. At an average cost of $0.20–$0.40 per disposable diaper, total diaper costs from birth to potty training run $1,000–$2,400.

Are cloth diapers actually cheaper than disposables?

Cloth diapers save $600–$1,200 over the full diapering period for a single child, with savings increasing for subsequent children using the same stash. The upfront cost for a full cloth diaper system is $300–$600. However, cloth diapers add water and energy costs (roughly $200–$400 over the diapering period) and significant time. For families with two or more children in diapers, the savings compound substantially.
