The Lansinoh NaturalWave baby bottle is designed to facilitate smooth transitions between breastfeeding and bottle feeding. This bottle features a soft, flexible silicone nipple that adapts to the baby's natural sucking movements, helping maintain their instinctive feeding patterns while supporting proper oral and jaw development. The NaturalWave nipple is engineered to minimize nipple confusion, making it particularly suitable for breastfed infants during times when direct breastfeeding is not possible. This set includes two 240 ml bottles with medium-flow nipples, constructed from durable, BPA-free materials. The ergonomic bottle shape provides comfortable handling for caregivers, and the wide neck design allows for easy cleaning and filling. The medium flow rate is appropriate for infants who have developed consistent feeding rhythms. All components are dishwasher-safe for convenient maintenance. The bottle system supports the natural latch and suck-swallow-breathe coordination that breastfed babies develop, offering a feeding solution that complements breastfeeding routines. The silicone material maintains flexibility across a range of temperatures, and the anti-colic vent system helps reduce air intake during feeding. The bottles feature clear measurement markings for accurate formula preparation.
