This design helps babies to easily accept the bottle and allows for smooth alternation between breast and bottle-feeding. Natural Shape: The natural shape of the NUK teat adapts perfectly to baby's sensitive palate, providing ample room for tongue and jaw movement. This helps in exercising their jaw and teeth, promoting healthy oral development.

This innovative venting system ensures a comfortable feeding experience for the baby. Temperature Control Indicator: The built-in Temperature Control indicator changes color from blue to white when the bottle's contents are too hot. This feature ensures that the milk is always at a safe and comfortable drinking temperature for the baby. Durable and BPA-Free: Each bottle is BPA-free and durable, ensuring safe and long-lasting use. The wide bottle neck allows for easy filling and cleaning, while the included sealing disc and protective cap help prevent leakage during transportation. Twin Pack: The customer receives two baby bottles in either Pink and White or Blue and White colors, providing convenience and value for parents. Overall, the NUK Temperature Control Baby Bottle offers a combination of safety, comfort, and convenience, making feeding time enjoyable for both babies and parents alike.
