Tackle Common Breastfeeding Issues: Our nipple shields are designed to help with flat or inverted nipples, as well as latching difficulties, soreness, and oversupply. Safe and Comfortable Material: Made from 100% transparent, soft, food-grade silicone, our nipple shields are ultra-clear, lightweight, and durable. They are also BPA-free and non-toxic. Innovative Design: Our nipple shields feature a split design with a detachable built-in valve and longer nipple, making it easier for your baby to get milk while reducing your pain. Secure Grip: The built-in valve completely encloses the nipple, so you don't have to worry about your baby pulling it off. The airtight, negative pressure design means the more your baby pulls, the tighter the fit. Natural Feel: Our nipple shields have a petal design that conforms to your body's curves, making them easier to fix in place. The imitated areola bulge also ensures that your baby and the nipple shield feel more realistic and natural.
