Abstract: An osmophore-pacifier. The osmophore-pacifier contains an odorant. When the osmophore-pacifier is sucked by an infant, it releases an odor which stimulates sucking behavior in the infant. The osmophore-pacifier includes a nipple, a shield portion, a matrix containing the odorant, and an air channel for releasing the odor. The odorant may be replaced with a different type of odorant in order to determine which odor stimulates continued sucking of the osmophore-pacifier, to promote sucking behavior, and to calm or soothe an infant in a state of agitation or pain.
