The Lansinoh 5 ounce Feeding Bottle features the Air Ventilation System (AVS) that reduces gas. It is a spill-proof wide-neck bottle. The nipple is slow-flow, 100% silicone, BPA free and has a hygienic protective cover.
My ebf son took bottles (even from me) until he was 8 weeks old and then decided he didn't want them anymore (the playtex ones). This bottle he took to immediately! I highly recommend them!
