Amazon.com Product Reviews:

The key feature of the Philips Avent newborn starter set bottles is the patented anti-colic nipple. It has an anti-vacuum skirt and one-way air valve that reduces air into the baby's stomach, and hence, reduces painful gas and colic. The natural shape and feel of the silicone nipple closely resembles the breast to make it easier to combine bottle and breastfeeding. The wide-neck bottles are easy to refill and clean. The cap seals the nipple to prevent leaking while mixing or traveling. The set includes two 4-oz. and three 9-oz. reusable bottles and five Avent anti-colic nipples, five dome caps, two newborn pacifiers with caps, and a bottle brush. --Scott Teal
