(Memphis) A new study shows 30 percent of mothers in this country can't afford to buy diapers.
That increases health risks for babies and moms.
Researchers at Yale University surveyed nearly 900 pregnant and parenting women, and nearly a third said they were in "diaper need."
An adequate supply of diapers costs $18 a week, according to the researchers.
That means a single mom making minimum wage of $7.25 per hour would have to pay more than 6 percent of her gross income to afford diapers.
St. John's United Methodist Church in Midtown Memphis has been trying to help mothers who are struggling, and is the area's only diaper bank.
Operation Swaddling Clothes began in 2009 and gives away 300 to 500 diapers a week.
The diapers are only given to clients who are pre-screened through MIFA.
Food stamps do not cover the cost of diapers.
Church members say parents who can't afford diapers are forced to leave their children in diapers much longer than they should.
"These kids can go through 10 to 12 diapers a day, and to have a child have one diaper for a day or 24 hours you see how miserable that would be for the child and the rest of the family," said Sarah Harr.
