The MAM Nipple Shields are a short term breastfeeding aid, used to protect sore or cracked nipples. They protect nipples during breastfeeding and allow you to breastfeed for longer. They are made from extremely soft, extra-thin, flexible silicone and have a “breast-like” feel. They are specially shaped to allow your baby to have skin contact with you while breastfeeding. This allows baby to feel and smell you and continue to stimulate your milk supply while suckling. Your baby will easily return to your breast once your nipples are healed. The nipple shields come packed in a fully sterilisable travel case. Please Note: These are Size 2 (Medium/Large) protectors.
