noun
lactation
lak-TAY-shun/lækˈteɪʃn/
The production and release of milk by mammary glands.
Hormones regulate lactation and help the body produce milk after childbirth.

Etymology
The verb meaning “to suckle” first gave a name to feeding an infant. The meaning later shifted to the bodily process that supplies that feeding: forming and secreting milk.
In context
Oxytocin is responsible for milk let down, while prolactin is essential for milk synthesis, production, and the maintenance of lactation.
