Breast-feeding comes with a cost to new moms that is often overlooked, according to a new study published in the American Sociological Review. The study looked at data from 1,313 first-time mothers in the U.S. who were in their late 20s or 30s when they gave birth.
Women’s incomes dropped precipitously when they choose to breast-feed for six months or longer -- and they remained low some five years after the babies were born, says the study’s lead author, Phyllis L.F. Rippeyoung, an assistant professor of sociology and coordinator of women’s and gender studies at Acadia University in Nova Scotia.
Rippeyoung’s interest in the hidden costs of breast-feeding was sparked by personal experience. When she became a mom, she was flooded with information about the benefits of breast-feeding -- including the suggestion that it would save her money.
“I thought that it was weird that they were saying it was free,” Rippeyoung remembers. “I was a grad student at the time driving back and forth between teaching and classes, and my milk was drying up since I couldn’t drive and pump at the same time. It was a very difficult thing, but I had to stop breast-feeding. If I’d continued I couldn’t have worked at the same time.”
The data for the new study came from the National Longitudinal Survey of Youth, which included information about the moms’ jobs and incomes, as well as stats on their family life, including the decision to give their babies formula or to breast-feed for a short duration (less than six months) or a long duration (six months or more).
