What Is A Let-Down Reflex?

  • A warm, heavy, tingling sensation that may occur with breastfeeding as breast milk increases and “lets down” to your baby. 
  • Cells in the breast begin to squeeze so milk is pushed from the breast to baby. 
  • Some mother’s feel a let-down and others do not feel this sensation. 
  • Baby’s sucking at the breast or crying, or maternal emotions may cause a let-down reflex to occur. 
  • Most women will have 3 to 4 let-downs during a single feeding but some never feel them. 
  • Stress or anger or fear can stop a let-down. 
  • If you are leaking at an inconvenient time, stop the reflex with pressure by folding your forearms across your chest and pressing firmly against your breasts and nipples.
