A sudden wave of sadness, anxiety, irritability, or dread arrives right before your milk lets down. Then, within a minute or two, it passes.
You are not imagining it, and it does not reflect how you feel about your baby or breastfeeding.
Dysphoric Milk Ejection Reflex, or D-MER, is a physical response to the hormonal changes involved in milk release. It is not postpartum depression, breastfeeding aversion, or something you need to “think positively” through.
Knowing what is happening often brings relief. Support helps too.
