The Meaning of "Breastfeeding" Is Changing and So Must Our Language About It

For millennia, the word "breastfeeding" has meant feeding an infant at his/her own mother's breast. With the recent introduction of high-efficiency breast pumps, other possibilities are now widely used, including feeding an infant his/her own mother's milk from a cup or bottle. This milk may be recently pumped or stored for a short or long time. Infants also may be fed another mother's milk. As a result, the use of the term "breastfeeding" to describe these different behaviors now inhibits clear communication among and between healthcare providers, researchers, mothers, and members of the lay public. We propose a comprehensive set of terms to describe these and related behaviors. Adoption and consistent use of these terms would facilitate communication among all interested parties on the topic of maternal lactation and infant feeding.
