Sterilize before initial use in boiling water in the closed position for 5 minutes or less (boiling over 5 minutes may damage the pacifier), allow to cool and squeeze the nipple gently to expel any water. Rinse before each use. Do not microwave, as the pacifier contains a metal part. Do not use dishwasher or steam sterilizers. Never dip pacifier in sweet substance as this can lead to tooth decay. Inspect the pacifier before each use and dispose immediately if damaged. Replace the pacifier after one or two months of use. This product is not recommended for bedtime use. Use this pacifier in an open position only, and under adult supervision.
