NUK Smooth Flow Bottles are the anti-colic solution for bottle feeding, featuring a unique nipple design that allows baby to control the flow rate for colic-free feeding. This newborn gift set includes: three 5 oz bottles, three 10 oz bottles, two replacement bottle nipples, two NUK 0-6m pacifiers, four Learner Cup accessories and one bottle brush. This Smooth Flow bottle nipple adjusts the flow based on how your baby drinks, adapting to their suction strength to ensure they will always have the right flow rate. The SafeTemp temperature indicator lets you know when milk is too hot with just a glance. The blue thermometer indicator fades when milk is too hot and reappears when milk has cooled and is safe to drink, and the Learner Cup accessories include soft spouts and handles, to easily transform bottle base into a sippy cup when your child is ready.
