The Dr. Brown’s Nipple Shield helps breastfeeding babies with latch-on challenges. It can also help train flat or inverted nipples and protect sore nipples while breastfeeding. It features 13 small holes in the tip that allow for smooth milk flow, and the patented design helps eliminate milk pooling to keep nipples dry. The comfortable 100% silicone shield is slightly stretchy for a secure fit. Made in the USA.
