Expression mode: This mode is designed to mimic the long sucking pattern of a baby's feeding. It involves a continuous, steady suction that helps express milk from the breast. Massage mode: In this mode, the breast pump applies short suction cycles combined with gentle massaging actions. The purpose is to stimulate milk flow by mimicking the initial rapid sucking motion of a baby. Auto mode: A combination of massage and expression modes. It alternates between cycles of short massage like suction and longer, steady sucking. The auto mode comes with 6 - 12 levels of adjustment.    Lactation mode: This mode is designed to closely resemble the natural sucking frequency of a baby. It typically starts with a gentle suction and gradually increases in intensity, replicating the way a baby's sucking pattern changes during a feeding session.
