This disclosure generally relates to a capacitive sensor for determining a fluid level in a milk container. In one embodiment, the capacitive sensor may be attached to a milk container of a breast pump device. The breast pump may include a breast shield adapted to at least in part receive a breast of a lactating user, an aggregate for generating suction for expressing milk from the breast, a milk container () providing a reservoir () for the expressed milk, a capacitive sensor () adapted to generate a signal indicative of the filling level within the reservoir () and a controller () for controlling the aggregate () and processing the signal of the capacitive sensor (), wherein the capacitive sensor () includes at least two capacitive sensor elements () having a different sensitivity to a change of the filling level and a similar sensitivity to a conductive object touching the milk container ().
