Natural Response Nipple: The nipple has a unique opening that releases milk only when the baby actively drinks. This design allows babies to drink, swallow, and breathe at their natural rhythm, similar to breastfeeding. It makes it easy to combine breast and bottle feeding, facilitating a smooth transition between the two. Anti-Colic Valve: The bottle is equipped with an anti-colic valve designed to keep air away from the baby's tummy during feeding. This helps reduce colic and discomfort, ensuring a more pleasant feeding experience for the baby. Wide, Soft, and Flexible Nipple: The nipple of the bottle is wide, soft, and flexible, mimicking the shape and feel of a breast. This design helps the baby to latch on easily and comfortably, promoting a natural feeding posture and reducing nipple confusion. Ergonomic Bottle Design: The bottle features an ergonomic design that is easy to grip at any angle. This allows parents to hold the bottle comfortably during feeding sessions, enhancing the bonding experience between parent and baby. Overall, the Avent Natural Response Feeding Bottle provides a nurturing and comfortable feeding solution that supports the baby's natural feeding instincts while offering convenience and ease of use for parents.
