U-grow Wide Neck Nipple, XL, Transparent (Pack of 2) New Born Flow Nipple  (Pack of 2 Nipples)

U-Grow nipples are designed to help babies feed from both the breast and the bottle. The nipple's standard shape is similar to the shape of a breast, and its soft, rounded nipple encourages the same peristaltic movements used to feed. Twin anti-colic valves keep air in the bottle and out of babies' tummies, making feeding and digesting more comfortable and reducing colic. The nipple is made from soft, durable silicone and has a design that prevents it from collapsing while your baby feeds.
