This breastfeeding bundle includes Medela contact nipple shields in both small 20mm and medium 24mm sizes to address a variety of breastfeeding challenges. Both nipple shield models feature an ultra-thin, soft silicone design with a cut-out area to encourage maximum skin contact between mother and baby for milk transfer and bonding. These BPA-free shields are designed to help with multiple breastfeeding issues like soreness, latch difficulty, flat or inverted nipples, and overactive letdown. Under guidance from a medical professional, these shields can help resolve many common breastfeeding problems. Having multiple nipple shield sizes in one bundle allows you to find the best fit as baby grows. The shields complement each other by accommodating changes throughout the breastfeeding journey. Both sets include 2 reusable shields and a carrying case for portability and safe storage. With this bundle, you can be prepared whether at home or on-the-go with spare shields protected. Medela designed these innovative shields to maintain breastmilk integrity and powerful nutrients that are vital for development while addressing breastfeeding challenges. Their goal is helping mothers successfully breastfeed for as long as they choose. This thoughtfully designed bundle provides multi-sized nipple shield solutions to support that journey.
