While the number of diapers each baby uses can vary, the average baby needs 8 disposable diapers in a day. This adds up to around 6,000 diapers in the first two years of a child’s life. According to the US Environmental Protection Agency (EPA), over 4 million tons of disposable diapers were estimated to have been tossed into landfills in 2018 alone. That’s a lot of soiled diapers!
