Before the first use, keep the pacifier immersed for 5 minutes in boiling water and let cool or sterilize cold. Before each use, clean the pacifier with warm, soapy water (no detergent or washing-up liquid). If a little water enters the breast shield during cleaning, expel it by slightly compressing the breast shield. Do not dip the pacifier in a sugary or medicated solution (risk of tooth decay). Replace the pacifier every 6 weeks for hygiene and safety.
