For every mom's feeding journey – bottle, breast, or both – Lansinoh's NaturalWave® Feeding Bottles are designed to make feeding easier for your baby and you. Our ultra-soft and strong NaturalWave nipples support a secure latch for baby-led feeding, while the advanced airflow system is clinically proven to reduce colic to help make gas and fussiness a thing of the past. Made from durable borosilicate glass designed to withstand extreme temperature changes and resist thermal shock, our premium glass bottles are safe for your baby and the environment. Cleanup is a snap with three easy-to-clean, dishwasher-safe pieces (excluding the cap), giving you more time to enjoy those special moments with your little one.
