A natural baby bottle is equipped with a Natural Response nipple, allowing the baby to control the pace, similar to breastfeeding. The bottle is designed with a unique opening and tip that only releases milk when the baby actively drinks. If the baby pauses to swallow and breathe, no milk flows from the bottle, just as it would at the breast. Our baby bottles are designed to make it effortless to combine breast and bottle feeding. The wide breast-shaped nipple has a soft feel that mimics the shape and feel of a breast, enabling the baby to control the flow of milk. The nipple also features a no-drip design to prevent any lost milk from the tip of the bottle, providing peace of mind. You can choose the Flow 3 nipple for the bottle. Additionally, the bottle includes an anti-colic valve, which is designed to minimize colic and discomfort by directing air away from the baby's tummy. In 2022, the baby bottles were recognized as the Best Baby Bottles Overall in the Forbes Vetted Best Baby Bottles To Encourage Happy Feedings Awards. Furthermore, Newsweek has named them a Best Parenting Product of 2022.
