Medela Harmony Pump and Feed Set

The Harmony Breast Pump is one of the few manual pumps in the world featuring 2-Phase Expression technology. The breast pump mimics the natural baby sucking behaviour at the mother's breast with short stimulating patterns followed by longer ones providing optimal milk flow.  The 2-Phase design simply means that to stimulate a let down (when your milk begins to flow) you begin pumping with the shorter side of the pump handle; this creates a faster sucking cycle, similar to that of a hungry baby. Once your milk starts to flow, you switch to the longer side of the handle which creates a slower sucking cycle to express the majority of your breastmilk.
