An aroma emitting pacifier for an infant gives off a predetermined scent by evaporation of volatile essential oils or similar substances. The aroma may be, for example, mint, menthol or eucalyptus, which may help relieve nasal congestion. The aroma emitting pacifier is constructed to prevent evaporation of the essential oil before activation, so that the nipple does not become contaminated with a flavor the infant may find unpalatable, and so that the oil is conserved until it is desired to administer it to the infant.
