Why Some Women Feel Intense Emotional Discomfort Just Before Milk Let-downFor some women, breastfeeding does not begin with calm or bonding. Instead, seconds before milk starts to flow, a sudden wave of dread, anxiety, sadness, or nausea hits without warning. It lasts only minutes, then disappears just as quickly. This experience is not psychological weakness, postpartum depression, or a lack of bonding. It is a recognised neurohormonal phenomenon linked to the milk ejection reflex itself. Known clinically as the Dysphoric Milk Ejection Reflex (D-MER), this response originates from shifts in dopamine levels in the brain, not from conscious emotion. Many women experience it silently, confused by feelings they cannot explain.
