Abstract
Abstract A pacifier having a fluid-filled chamber removably secured to a nipple by a threaded collar and locking ring assembly includes means for controlling the volume of fluid delivered through the nipple, the means comprising an absorbant material within the nipple which acts as a barrier to restrict the flow of fluid therethrough. The pacifier can also be used without the locking ring whereby the threaded collar is secured to the threaded neck of a nursing bottle.
