What is 2-Phase Expression Technology?
2-Phase Expression Technology simulates a baby’s natural nursing rhythm more precisely than any other system. It is known that babies change the way they suckle at a mother's breast during breastfeeding. Initially, they suckle rapidly to stimulate the Milk Ejection Reflex (MER) and induce "let-down". Once the milk starts flowing, the speed of the baby's sucking decreases for the actual feeding phase.
This is the only research based breast pump technology to mimic a baby's natural nursing rhythm. The unique combination of a rapid stimulation and slower expression makes pumping especially gentle, comfortable and efficient.
