The Medela Contact Nipple Shield (Small) is a breastfeeding aid designed to help mothers experiencing latching difficulties or nipple discomfort. Made from ultra-thin, BPA-free silicone, it provides a protective layer while maintaining skin contact between mother and baby. This product is a personal hygiene item intended for individual use. The nipple shield should be thoroughly cleaned and sterilized before first use and after each feeding. Proper sizing is important for optimal effectiveness - the small size is typically 16mm. Store in a clean, dry place when not in use.
