NUK Silicone Orthodontic Nipples, 6 Months, Fast, 6 Pack

Every NUK nipple features the NUK Air System - a unique venting system - which helps reduce colic. The natural shaped nipple mimics Mom's to help make baby's transition from breast to bottle a seamless one. This unique nipple also has the drinking hole specially located on the top side - not the tip like round nipples -- which allows the milk to mix more effectively with saliva and promote easier digestion. NUK Orthodontic Replacement Nipples are silicone, fit all NUK wide neck bottles and are available in sizes Slow Flow (0-6 months), Medium Flow (6-18 months) and Fast Flow (18+ months).
