Feeding is the most important job of any parent, and keeping it as natural as possible only makes the process better. The Olababy Gentle Bottle is prefect for when baby is switching from breast feeding to bottle feeding. Designed to mimic a natural breast, the nipple design allows for easy latching and reduces bottle rejection. Dual-venting was integrated into the design as an anti-colic system, and to help with air flow. The off-centered nipple allows for better outflow and reduces leftover residue. A wide neck makes it easy to hold, as well as clean. Made with medical-grade silicone, the Gentle Bottle is 100% BPA, PVC, and Phthalate free. Designed with baby in mind, the Gentle Bottle keeps feeding as natural as it should be.
