Lactivism

Lactivism (portmanteau of "lactation" and "activism") is a term used to describe the advocacy of breastfeeding. Advocates, referred to as "lactivists", seek to promote the health benefits of breastfeeding over formula-feeding and to ensure that nursing mothers are not discriminated against.

One form that lactivism can take is the staging of a "nurse-in" (a play on "sit-in"), which involves women gathering in public to breastfeed their children, usually to protest incidents in which a nursing mother was asked to cover up or leave a location because she was breastfeeding.

Often during nurse-ins, breastfeeding mothers will sometimes wear clothing with the International Breastfeeding Symbol on it, to show their solidarity.
