ABSTRACT:
An apparatus is set forth including an outer, cylindrical shell formed with a tapered upper end defining an upper opening therethrough for receiving a nursing bottle of predetermined length equal to the axial length of the shell. A plurality of diametrically opposed conduits are intergrally affixed to opposed interior side walls of the shell aligned with fluid indicia formed on an exterior surface of the shell. A chemi-luminescent fluid is contained within a base pouch, the base pouch includes a plurality of spaced arms for reception within the diametrically opposed conduits with a threaded cap secured to a lowermost end of the shell. Remaining nursing fluid within a nursing bottle displaces the chemi-luminescent fluid within the pouch and directs said fluid upwardly for indication of remaining nursing fluid within the nursing bottle based on weight displacement of the nursing bottle on the chemi-luminescent fluid.
