The AVENT Standard Nipple Protectors helps to protect sore nipples during breastfeeding. Made with odourless, tasteless, and ultra-fine silicone, baby can still feel and smell your skin and continue to stimulate your milk supply while suckling, and will return easily to the breast once your nipples are healed. Please note that nipple protectors are only designed for use when you have sore or cracked nipples and should be used with health professional advice.
