Breastfeeding can bring unexpected challenges like Dysphoric Milk Ejection Reflex (D-MER), causing brief, intense negative emotions just before milk let down. D-MER is linked to hormonal changes, not psychological issues or disliking breastfeeding. Symptoms include sadness, dread, and anxiety, lasting 30 seconds to two minutes. It's distinct from postpartum depression but can occur alongside it. Manage D-MER with skin-to-skin contact, relaxation techniques, and support.
