Nuby’s Comfort Silicone Bottle with Slow Flow Nipple and 360 Weighted Straw helps make bottle feeding a smoother, more natural process. The bottle features a Soft Flex nipple that mimics mom’s breast shape and encourages latch-on, easing the transition between breast and bottle. The Soft-Flex nipple has built-in Anti-colic valves to help prevent the ingestion of air, which may cause colic. The slow-flow nipple keeps newborns from feeding too quickly. To make feeding time more comfortable, Nuby has included a 360 weighted straw that allows babies to feed in an upright position, reducing reflux.  The flexible silicone bottle allows parents to assist in feeding by gently squeezing the bottle. Nuby’s Comfort Bottles helps parents and baby enjoy the little moments with less fuss! • Age Range: 0 months and up • Holds 5 oz/150 ml of formula or milk • Slow flow silicone nipple is ideal for newborns
