Make it easier for your little one with a nipple designed to help transition from breastfeeding to bottle feeding and back. Lansinoh's NaturalWave baby bottle nipple supports your baby by promoting the same natural feeding actions they learned while breastfeeding and is clinically proven to reduce nipple confusion. The soft, flexible silicone has an anti-colic air ventilation system to reduce intake air, a potential cause of colic or spit up. Dishwasher safe and BPA/BPS free.
