Yes! An average child who potty trains at age three will have used about 8,030 diapers. Using average US prices for disposable diapers those 8,030 diapers would cost $2,007.50. On the other hand, an adequate number of moderate-to-high priced reusable diapers to last that entire time would only cost about $432. This means reusable diapers save about $1,575.50 USD per child; and most often those same diapers can be reused on the next child saving the full cost of diapering that second child. Cha-ching!
