Dysphoric milk ejection reflex to nipple/areolar stimulation, thoughts of the baby or of breastfeeding, or overfull breasts, travels through both brain and bloodstream, causing emotional changes in the brain and the release of milk in the breast. Prolactin, released in a gradual wave that peaks after the beginning of a feeding, is responsible for continued milk production. Dopamine inhibits the release of prolactin, so dopamine levels must drop in order for prolactin levels to rise. Some speculate that the necessary dopamine drop is similar to (and timed with) the oxytocin spike – a sort of negative image – but that in D-MER mothers it
Milk substitute Milk substitute A milk substitute (or, more precisely, an analogue of mammalian milk) (also called milk alternative or milk analogue) can refer to a liquid considered (particularly in the USA and other western countries) as a replacement for the milk from a mammal (mainly cows and humans). Mammalian milk analogues are white or whitish liquids that resemble either dairy or human breast milk.
