The Philips Avent Natural Response SCY960/03 bottle nipple is designed for infants aged 0-6 months, facilitating the transition from breastfeeding to bottle feeding with its natural shape that resembles the mother's breast. This design helps infants accept the nipple more easily while adapting perfectly to the baby's mouth structure. The nipple supports proper oral cavity development in infants and is constructed from durable silicone material that does not leak. This model includes a practical set with sizes for 3-6 months and 6+ months, specifically containing 2 pieces for 6+ months and 3 pieces for 3-6 months. The product focuses on creating a comfortable feeding experience by maintaining a natural feel that mimics breastfeeding, which can help reduce resistance during feeding transitions. Its adaptive design responds to the baby's sucking rhythm while maintaining structural integrity during use. The silicone construction ensures consistent performance and easy cleaning, with the material selected for its durability and safety standards. This bottle nipple set addresses the developmental needs of infants during their first six months, providing reliable functionality for daily feeding routines. The product's design prioritizes both infant comfort and practical utility for caregivers, with attention to details that support natural feeding motions. Each nipple in the set is engineered to maintain its shape and function through repeated use and sterilization processes. The combination of sizes allows for appropriate progression as the infant grows and develops different feeding patterns. This product represents a thoughtful approach to infant feeding accessories, balancing physiological considerations with practical application requirements.
