The international breastfeeding community includes people who actively promote breastfeeding, teach breastfeeding, research breastfeeding and related health issues, and who write about breastfeeding and the ways it influences mothering, parenting and family life.

When La Leche League (LLL) was organized in 1956, it became a central place of contact for women looking for information, researchers and health professionals searching for peers, mothers hoping for encouragement and support, and writers wanting to connect with each other and share knowledge and insight.

As breastfeeding women began to join League and attend meetings they also became a willing market for publications about nursing and parenting. La Leche League conferences (local, national and international) created venues for speakers, for researchers to present their findings, and for new books to be released. As more women became college educated and entered the work force, they began to create new health fields, such as lactation consultation. Today, there are lactivists, women and men who actively promote the health benefits of breastfeeding for mothers, babies and communities, and who protest companies and corporations who discriminate against breastfeeding women.

With the development of the internet, individual women can share their breastfeeding experiences, sites can be created that address medical issues, research can be shared throughout the world, and governments can promote breastfeeding as a tool to improve the general health of their entire populations.

This list starts small, with the names of the founders of La Leche League, and then links to articles about the most well-known writers and researchers in the field of breastfeeding today. It includes the most authoritative sites with breastfeeding information, and some smaller sites that address important aspects of breastfeeding. The world health community encourages breastfeeding with sites aimed at a national and international audience.
