When you switch on the pump, it will start in Stimulation Mode to gently help initiate your milk flow, then automatically switch to Expression Mode after 2 minutes if you are not using the app.
For mums who are first starting to pump with the Wearables, you may begin with Speed: 3 and Intensity: 5 in Expression mode. From there, feel free to gradually adjust the settings to whatever feels most comfortable and natural for you.
