Abstract: An apparatus for assisting a two-breasted wearer of a nursing brassiere in determining which breast was most recently used for nursing or which breast should next be used for nursing is disclosed. Some embodiments include a flexible element attached to the brassiere at a first end and coupled at a second end to either of two portions of the brassiere, with the coupled portion reminding the woman to use a particular breast. In other embodiments, attachment of the flexible element to a portion can restrict access to the non-preferred breast. In other embodiments, an indicator attached to the brassiere can be placed in at least two states, each indicating a preference for a particular breast. In other embodiments, an alternating release switch on the brassiere automatically releases a coupling element of a breast cup associated with a preferred breast.
