Philips AVENT BPA Free 9-Ounce Natural Feeding Bottles (3 Pack) with Slow-Flow Nipples promote the health and comfort of your baby. Whether you are breastfeeding, bottle feeding, or combining the two, these AVENT feeding bottles support your choices. Developed using extensive research and clinical trials, these BPA-free bottles are proven to reduce fussiness* and colic. Designed for infants older than one month--but suitable for breastfed babies of all ages--the bottles each have a 9-ounce capacity and an extra-soft silicone Slow-Flow nipple with two holes, making them ideal for medium-sized feedings. Slow-Flow Nipples are Ideal for Breastfed Babies of All Ages AVENT Slow-Flow Nipples are a dual-hole extra-soft silicone nipples intended for infants older than one month, yet they can be used by breastfed babies of all ages. Working with your baby's natural feeding rhythm, the nipples let your baby control the flow, more like breastfeeding, which can help reduce overeating and spit-up. Also, the nipples' natural shape promotes proper latch-on and makes it easier for your baby to switch between breast and bottle. Each bottle features a two-piece anti-colic system that consists of the AVENT nipple and adapter ring. As your baby feeds, the unique skirt on the nipple flexes to allow air into the bottle and prevents any vacuum build-up. Listen for the gentle whistling sound and watch the air bubbles burst on the surface of the milk. That's your guarantee that the air is being released into the bottle--not into your baby's tummy. Works with Full Line of AVENT Pumps, Bottles, and Cups Like all AVENT bottles, the Natural Feeding Bottles work interchangeably with the entire line of AVENT pumps, bottles, and cups. While the 9-ounce bottles feature double-hole Slow-Flow nipples, you may use different AVENT nipple, bottle, and cup styles to meet your baby's changing needs. If you prefer different AVENT nipples for these bottles, simply switch out the nipples for ones with a different flow. Each nipple style is imprinted with a number, making it easy to identify and customize your AVENT bottles. Easy to Clean and Use These hygienic bottles are easy to clean and assemble, as there are no small parts. The dome cap securely seals the AVENT nipple to ensure leak-proof feeding, mixing, and travel without the need for separate sealing discs. Shaped for stability and comfort, the bottles' waisted shape makes it easy to hold, while its wide-neck design makes filling a cinch. Clear markings on the bottles ensure accurate measurement and make it simple to determine how much your baby has eaten. All components of the Natural Feeding Bottles are BPA free.
