Baby Brezza Natural Bottles are a breeze to feed & clean. With only 2 parts and an ultra-wide mouth, they are the only natural bottle that’s easy to clean & assemble. And your baby can easily transition between breast & bottle with its wide, breast-like nipple. Each nipple features the TruFlo® Anti-Colic System so your baby swallows milk, not air. BPA-FREE. Available in four trendy colors (charcoal gray, white, blue and pink). You and your baby will love them!
