PHASES OF WILLOW
While pumping, you are going to hear several different sounds that indicate which phase
you are in. Many women transition to Expression within 2 minutes, but this can vary.
If at any point you experience excessive discomfort, decrease suction or pause the
pump, then break latch and make sure you are aligned properly.
