They feature a wide textured base and flexible tip to mimic natural breastfeeding, along with an advanced airflow system to reduce colic and gas. Compatible with all Lansinoh bottles and clinically proven to reduce nipple confusion, these nipples are made from 100% BPA/BPS-free silicone and are recommended for babies 3 months and older. Some users note the medium flow may be fast for younger infants and that nipples may experience tearing over time.","url":"https://kidsy.co/products/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count","brand":"Lansinoh","condition":"new","product_category":"Baby & Toddler > Nursing & Feeding > Feeding Essentials > Baby Bottle Nipples & Liners > Baby Bottle Nipples > Wide Neck Nipples","material":"100% food-grade silicone","item_weight_unit":"lb","age_group":"infant","image_url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count-4694269.jpg?v=1782209721","additional_image_urls":["https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count-5306438.jpg?v=1782209721","https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count-3567967.jpg?v=1782209721","https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count-7356564.jpg?v=1782209721"],"images":[{"id":"img-1783486413235-0","url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-lansinoh-naturalwave-medium-flow-bottle-nipples-4-count-4694269.jpg?v=1782209721","width":1500,"height":1500,"alt_text":"New Lansinoh NaturalWave Medium Flow Bottle Nipples 4 Count product image (primary)","position":1,"attributes":{"mood":["clean","fresh","calm"],"text":"Clinically proven to reduce nipple confusion.
