The breast detector is configured to detect the first or second condition based on operating parameters of the pressure source. The controller is configured to control the operation of the pressure source in the said first operating mode when the breast detector has detected the first condition, or in the said second operating mode when the breast detector has detected the second condition. In the said first operating mode, the pressure source is configured to create a reduced pressure enabling the breast to move inside the chest receiver. A method for controlling the operation of a breast pump and an information storage medium containing program code means for performing the steps of the method for controlling the operation of a breast pump are disclosed.
