A rise in breastfeeding comes at expense of mothers' careers, new study finds

Breast is best, or so the campaign launched by the World Health Organization and the Centers for Disease Control and Prevention says.

But regulations encouraging breastfeeding may come at a steep price, according to new research from the University of Georgia.

The new study published in the American Economic Journal: Applied Economics found that state hospital regulations aimed to encourage breastfeeding, such as requiring a lactation consultant on staff, increased the likelihood that new mothers would start breastfeeding by almost 4%.

The regulations also increased the probability that the women continued breastfeeding through the first year of their children's lives by as much as 7%.

However, mothers who chose to breastfeed significantly increased their time spent on child care, leading many to reduce their , reduce their positions to part time or leave the workforce entirely. And that may cause substantially lower wages and earnings down the line.

"These types of policies enable women who would like to breastfeed who previously did not have sufficient support or information to be able to do that," said Emily Lawler, co-author of the study and an assistant professor in UGA's School of Public and International Affairs. "The bigger picture is that the U.S. has really focused on pushing breastfeeding as a goal, but we have done that without thinking through all of the relative costs of that decision."

More breastfeeding may mean less time for formal work

One of the biggest costs of breastfeeding, the study found, is loss of time.

During the first few days after birth, babies can eat as often as every hour, according to the CDC. As they get older, they still require eight to 12 feedings in a 24-hour period over the first six months of their lives.

And many breastfeeding organizations suggest women who begin pumping should do so every couple of hours. On average, pumping takes 15 to 20 minutes, not including the time spent bottling milk and cleaning the machine's parts after each session.

The researchers found women with infants reduced their labor force participation by up to 3%.

"Breastfeeding is a uniquely gendered activity, and it causes women's time to shift away from formal work," Lawler said. "Meanwhile, these breastfeeding policies don't cause anything to really change for dads. They don't work more after the baby is born, and they also don't work less."

Only 16 states have hospital policies encouraging breastfeeding

Most states don't have this type of hospital policy to promote breastfeeding. Only 16 states had regulations in place during the study period, and the requirements vary greatly.

The most common guidelines require all new mothers be informed of the benefits of breastfeeding, that hospital staff be regularly trained on initiation and support of lactation, and that there be a lactation consultant on staff.

The researchers relied on data from the National Immunization Survey-Child, a nationwide study focused on and vaccination rates, to compare the effects of these policies on breastfeeding rates.

They examined the impacts of the policies using data from the American Time Use Survey, a national study by the U.S. Bureau of Labor Statistics focused on how people divide their time between work, , volunteering and more, and the Current Population Study, a comprehensive body of labor statistics data from the Bureau of Labor Statistics.

Breastfeeding costs versus benefits

Breastmilk is considered the gold standard of infant feeding by most, if not all, health organizations.

Previous research found that breastfed infants have lower risks of skin rashes and some gastrointestinal issues.

"When you dig into the evidence about the of breastfeeding versus a high-quality formula, it's really, really sparse," Lawler said. "In general, women who breastfeed look different from those who don't. They tend to be higher educated, have and can invest in their children in a way that non-breastfeeding women may not be able to."

Those factors, the researchers argue, make it hard to determine whether the health benefits attributed to breastfeeding are purely due to breast milk and not some other confounding factors.

"This study is the first piece of evidence that we have on what the costs of promoting breastfeeding and encouraging people to breastfeed look like for maternal employment and work," Lawler said. "I don't think we should view these findings as a signal that is not worth it because it has these costs. But these costs are important to acknowledge and to take into account when we're thinking about implementing policies like paid .

"Policies that provide women with paid leave can be a really important way of enabling them to make the decision to breastfeed while also not harming their career trajectory in the long run."
