Before first use, keep the pacifier immersed in boiling water for 5 minutes, then let it cool. Or cold sterilize using Dodie sterilization tablets. Squeeze the breast shield to release any water it may contain. This is for hygienic reasons. Before each use, clean the pacifier with warm soapy water then rinse. Never give your child a pacifier whose teat has been soaked in food or medicinal substances (risk of tooth decay and ingestion). Replace the pacifier every six weeks as a health and safety measure.
