This Boon Nursh baby bottle and sippy cup lid bundle is perfect for feeding your little one from birth through their transition to a sippy cup. The bundle includes a set of three 4-oz Boon Nursh silicone baby bottles featuring an innovative collapsible silicone pouch design that eliminates air during feeding to reduce colic. The stage 1 slow flow nipples provide an easy latch and natural feel. Also included are three Boon Nursh silicone sippy cup lids that fit perfectly onto the Nursh bottles to convert them into familiar sippy cups for babies aged 6 months and up. The 100% silicone construction of both the bottles and sippy lids means you can safely sterilize all components. With this bundle, you get the benefits of the unique Nursh bottle for newborn feeding along with the option to smoothly transition to a sippy cup using the same trusted bottle shape your little one is used to. This helps ease the transition process. Both the bottles and sippy lids are conveniently dishwasher safe.
