Philips AVENT SCF693/44 N/Atural 9 Ounce Teal Bottle is the most N/Atural way to bottle feed. The wide, breast-shaped nipple promotes N/Atural latch-on so you can easily combine bottle feeding with breastfeeding. The unique comfort petals inside the nipple increase softness and flexibility to prevent nipple collapse, and the innovative twin valve, anti-colic slow-flow nipple helps newborns feed comfortably and easily. The ergonomic shape makes it comfortable for parents to hold and easy for small fingers to grasp. Assembly is simple with only a few parts and the wide bottle neck makes filling and cleaning easy. The N/Atural bottle is made from polypropylene, a BPA free material, and works with all nipples and caps from the N/Atural bottle line.
