Playtex Baby Anti-Colic Bottle Gift Set provide complete tummy comfort for easy switching between breast and bottle feeding. VentAire Bottles are designed with doctor-recommended features that help prevent colic and reflux. The patented bottom vent promotes an air-free feed, and the ergonomic, angled design promotes semiupright feeding to help prevent ear infections. Unlike nipple vented bottles, VentAire's bottom vent keeps air at the back of the bottle and prevents it from mixing with milk as your baby drinks. Less air bubbles in your baby's milk means reduced colic, reflux, gas, burping and fussiness. Playtex Baby offers a variety of uniquely designed bottles that meet all of your baby's changing feeding needs. All Playtex Baby products are BPA, PVC and Phthalate Free. This set has the essentials to help you. The Playtex Baby Anti-Colic Bottles feature the micro-channel vent technology that helps prevent mixing air from mixing with milk, and the Natural Shape Wide nipple that is shaped like the breast with a wide raised, textured area that helps baby latch on for easier breast-bottle transition. Plus the angled bottle supports the semi-upright feeding position that helps prevent ear infections. Includes: 5 VentAire advanced wide bottles (3 6oz. and 2 9oz.). Extra nipples (both slow and fast flow), extra bottle caps, extra vent disks. A clinical study confirms that babies using the Playtex Baby Anti-Colic Bottles had less gas, spit-up, colic and other discomforts than with other leading bottles. BPA Free.

DOCTOR RECOMMENDED FEATURES - The bottom vent for air-free feeding and the angled design for more upright feeding are doctor recommended to help reduce reflux, colic, gas, burping and spit up. NIPPLE DESIGNED TO FEEL LIKE MOM - Designed to be most like mom, the wide shape Naturalatch silicone nipple encourages proper latching, promotes healthy feeding and allows you to easily switch between breast and bottle feeding. EASY TO CLEAN & REASSEMBLE - Ventaire bottles are designed with fewer parts, making cleaning and reassembly quick and easy.
