Buy reusable cloth diapers not only for a cleaner environment (disposables can take 250-500 years to decompose), but also for the health of your baby. The average parent uses 6,000 - 8,000 disposable diapers before their child is potty-trained. These diapers contain sodium polyacrylate, the same substance removed from tampons in 1985, and dioxin, listed by the EPA as the most toxic of all cancer-linked chemicals.
