The Lowdown on Letdown

Letdown is a reflux that makes your milk flow. It is generally activated by sucking, but even hearing a baby cry can trigger a letdown. How it feels is a wide spectrum, ranging from no sensation at all to both physical and emotional sensations. Here's the lowdown.

What you'll learn

Letdown, as known as Milk Ejection Reflex or (MER), is a reflex that makes breastmilk flow. When a baby begins to suck, two hormones – prolactin and oxytocin – are released into your bloodstream. Prolactin helps create milk, while oxytocin causes the flow. Many parents report feeling little to nothing during letdown, while others associate it with negative emotions, a sensation known as D-MER. Whether you feel tingles or nada, this video will give you the lowdown.
