A study from 2013 found that almost 30 percent of pregnant women and new moms were in need of diapers.
The study, entitled "Diaper Need and Its Impact on Child Health," surveyed 877 pregnant and parenting women; it was published in the medical journal "Pediatrics."
The Atlantic notes that it costs about $936 for a year's worth of diapers, which would gobble up 6 percent of the annual pay of a single mom who is working for minimum wage in a full-time job.
The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and Supplemental Nutrition Assistance Program (SNAP) do not cover diapers.
According to the Atlantic, the 2013 study found that low-income moms were forced to clean out dirty diapers and put them back on the kids and/or have their babies sit in wet diapers, which can cause infections. Some mothers tried potty training babies that were not even a year old.
The study also found that moms had to get diapers from an agency, family, friends and churches.
For many moms, a lack of clean diapers means they can't put their kids in daycare centers that require a supply provided by the parent.
Megan Smith, one of the study's co-authors, works at The New Haven MOMS Partnership, an organization that provides moms with diapers, help with finding jobs and classes on how to manage stress.
