The wide-necked bottle with NaturalWave teat from Lansinoh is optimally shaped and easy to hold thanks to its ergonomic shape. The bottle is made of bisphenol A-free materials. Thanks to the wide opening, the wide-necked bottle is easy to fill and clean. The NaturalWave wide-neck bottle is also compatible with all Lansinoh breast pumps. The large wide-neck bottle (240 ml) comes with a size M teat. The NaturalWave teat is as similar to the breast as possible in shape and texture. It allows the baby to maintain its individual sucking pattern learned during breastfeeding. The teat tip is soft and exceptionally stretchy, can be optimally compressed and fits perfectly to the palate of the baby's upper jaw. The wide teat base with anti-stick texture enables optimal mouth closure and effective sucking. The AVS valve reduces air swallowing and possible colic. The NaturalWave teat is made of 100% extra soft, stretchy silicone. The long round teat tip ensures a precise fit in baby's mouth - reinforced on the inside for more stability. The gentle tilt of the NaturalWave teat allows baby to enclose the teat with lips turned up. The baby is able to regulate the flow of milk with any size of hole, because the bottle does not drip on its own. The protective cap closes without dripping and is hygienic. For mindful feeding with the baby bottle, the NaturalWave teat from Lansinoh is a good alternative for providing babies with valuable breast milk. The Lansinoh wide-neck bottle is available as a plastic and glass bottle.
