New One Philips Avent Natural 4 oz Bottle

From company: The Natural Bottle from Phillips Avent is the most natural way to bottle feed because it comes closest to feeding from the breast, which allows moms to easily combine breast and bottle feeding. Wide breast-shaped nipple promotes natural latch-on, while unique comfort petals inside nipple increase flexibility and stretch to prevent nipple collapse Advanced anti-colic system with twin valve design vents air into bottle instead of baby's tummy.
