SACO — In the United States, one in three families with children who use diapers have difficulty affording the number of diapers their family needs, according to studies done by the National Diaper Bank. The bank serves 24 to 40 families each week, distributing, on average, 1400 to 2000 diapers every Wednesday, said volunteer Pam Mohlin. Using an adequate amount of diapers decreases incidents of diaper rash by 33 percent and babies with adequate diapers who get rashes have less severe outbreaks, experiencing 77 percent fewer days of rash than babies without an adequate diaper supply, according to the Connecticut Center for Economic Analysis
