The Philips Avent 4 ounce natural glass baby bottle is the most natural way to bottle feed. The wide, breast shaped nipple promotes natural latch on so you can easily combine breast and bottle feeding and the unique comfort petals provides an extra soft, flexible nipple without nipple collapse. In addition, the anti-colic newborn-flow nipple helps newborns feed comfortably and easily and 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. This Avent Natural bottle is made from glass, a BPA-free material and works with all nipples, rings, and caps from the Natural line . To prevent leaks, check to make sure the plastic screw ring has not been over-tightened on the bottle. The bottle is screwed tight enough when you feel some resistance when attaching the screw ring to the bottle. At that point, please stop. Over tightening the screw ring may lead to damage.
Advanced anti-colic system is directly integrated into the nipple with no extra hard-to-clean parts
