Breastfeeding and first foods--including human milk and infant formula--affect us all as individuals and a society of eaters and feeders. They also shape us in part through having significant effects on community health and well-being, workplace strength, and environmental integrity. In addition, we all affect breastfeeding and first foods. Society, the economy, and the environment constrain and enable breastfeeding success, for example, and they often do so differently by race, class, and other social categories. It is important we recognize and address these realities for our own individual interests as well as those we as a citizenry hold in common.
