Little Fingers BPA-Free Natural Feeding Nipple for Newborns Babies Compatible with Feeding Bottle 290 ML and 180 ML in Transparent (Pack of 2) Medium Flow Nipple  (Pack of 2 Nipples)

Natural slow flow nipples are designed to help babies combine breast and bottle feeding. The nipple's wide shape is similar to the shape of a breast, and its soft, rounded nipple encourages natural latch on. A unique petal design increases flexibility and helps prevent nipple collapse while your baby feeds. Also, the advanced, twin anti-colic valves keep air in the bottle and out of babies' tummies, making feeding more comfortable. The nipples are made of soft, durable silicone. The slow flow rate nipple is designed for babies who are at least one month old.
