A liquid dispensing pacifier having interchangeable components is provided. The pacifier includes a hollow, porous nipple secured to a shield and having a base thereon for attachment to other components. The nipple can be disposed directly on the opening of a baby bottle for feeding, or to a syringe to facilitate administration of medicine. Alternatively, the pacifier can be secured to one end of an elongated straw and the straw can be threaded through a lid secured to a baby bottle and disposed within the liquid content therein. In this way, a baby can suck on the pacifier to draw liquid from the bottle without having to hold the bottle. Additionally, the straw can be secured to the pacifier, and the pacifier can be attached directly to a baby bottle to feed a baby in the conventional manner.
