When needed, nipple shields help support pain-free breastfeeding by making it easier for the baby to latch on, and protecting and relieving the severely stressed nipples. The special tulip shape means that the baby experiences the smell of its mother close up. Comes with a storage box for increased portability and hygiene. Available in Small (16mm), Medium (20mm), and Large (24mm) sizes. Includes one pair (2) contact nipple shields with carrying case.
