Prior to first use and after each use, wash with hot water and mild detergent then rinse clean. Then sanitize by boiling in water for 5 minutes. Never put the nipple shield in the dishwasher as this may result in damage to the material. For use during breastfeeding. Sanitization in a pan with latex products may lead to discoloration. Before placing the nipple shield on the breast, the inside wings should be moistened with water or breast milk for best adhesion. Pull the wings slightly outwards and place the nipple shield over nipple with the logo facing downwards. During breastfeeding, the nipple shield should be held in place with the fingers lying flat under the breast and the thumb lying above the nipple. Store clean and dry, away from direct sunlight. For storage, place the clean and dry nipple shield with the open side up in the lid of the box, then close. Do not use as a baby bottle nipple.
