Abstract: The present invention is referred to a nursing breast pad, comprising a circular pad including a front garment facing surface and a rear wearer facing surface attached to each other by a peripheral flange. The space between the garment facing surface and the wearer facing surface contains a liquid chemical and a powder chemical that, when mixed together, can produce an endothermic cooling action. The liquid chemical is contained within a flexible bag that, when squeezed by the user, causes the bag to burst so that the two chemicals can mix.
