Rippeyoung PLF, Noonan MC. Is breastfeeding truly cost free? Income consequences of breastfeeding for women. Am Sociol Rev. Apr 2012;77(2):244-267.
This study acknowledged the health advantages of breastfeeding and investigated whether there might be economic consequences, as well. Using data from the National Longitudinal Survey of Youth, the results showed that mothers who breastfed for 6 months or longer suffered more severe and more prolonged earnings losses than did mothers who breastfed for shorter durations, or not at all.
