Marian Tompson

Tompson was instrumental in developing Breastfeeding Seminars for Physicians hosted regularly by La Leche League and held annually since 1973.

[2]; the Advisory Board for the National Association of Post Partum Care Services (1995), the Advisory Committee for Perinatal Health, Department of Public Health for the State of Illinois (1983); and served as a consultant for the WHO/UNICEF meeting on Infant and Young Child Feeding in Geneva, Switzerland in 1980.

When questions and concerns about connection between breastfeeding and HIV/AIDS arose in the late 1990s, Tompson began to ask for the available research.

In 2024, Tompson resigned for La Leche League, over disagreements about breastfeeding by trans women, writing in her resignation letter that the "shift from following the norms of nature, which is the core of mothering through breastfeeding, to indulging the fantasies of adults, is destroying our organization.

"[1] In the September/October 1982 issue of Mother Earth News, Mrs. Tompson was interviewed about La Leche League and the benefits of homebirth.
