These pacifiers are made from pure, natural rubber in their entirety; one piece, no cracks or crevices, easy to clean! Natural rubber is softer than silicone, giving it a more skin-like quality. These pacifiers are extremely hygienic, given that the entire pacifier is molded and created in one piece (no cracks or crevices to trap bacteria). Sizing Sizing is rated by baby's age (full term). The portion that goes in the mouth gets larger with larger sizes, corresponding to baby's growing body. Small: 0-6 monthsMedium: 6-18 months Materials Made from 100% natural rubber. Care General CareClean after each use with warm water and mild liquid soap. Never wash in the dishwasher.Store pacifier in a dry, clean container away from direct sunlight and excessive heat. Pacifier will darken over time with everyday use; this is perfectly natural and expected. How to prepare for first useBefore first use, sterilize for 5 minutes in boiling water, then allow to cool. Prior to sterilizing, you may notice a "rubbery" smell and oily coating. This is perfectly natural, due to a film of oil from the rubber tree that preserves the pacifier while packaged and will disappear with sterilizing.NOTE: If pacifier nipple stick together when pressed or if pacifier feels sticky overall, replace with a new one. It is recommended that these pacifiers be replaced every 6 to 8 weeks.
