Avent Disposable System Newborn Nipples Feeding with the Avent system offers the next best thing the breastfeeding. That's because the natural-shaped Avent silicone nipple is broad and soft to feel as close to the breast as possible. Since baby uses the same suckling motion on the Avent bottle as on the breast, transition is easy, giving moms the freedom and convenience they need to make choosing and continuing to breastfeed even easier. The Reusable Avent Bottle with nipple can reduce incidents of painful gas after feeding. The key is the nipple with its patented anti-vacuum skirt with one-way air valve. While feeding, the one-way air valve opens and closes with baby's natural suckling rhythm to let air flow into the bottle, eliminating the vacuum that can form. That means with Avent, baby enjoys less air in the tummy and fewer incidents of post-feeding discomfort related to colic. The Disposable Avent Nurser with blue-tinted nipple features the same natural shape and feel, and anti-collapse tip as the clear nipple for the reusable bottle, but without the anti-vacuum valve. Instead the disposable nurser uses collapsible liners to control air ingestion during feeding. Both the Avent Reusable Bottle and Disposable Nurser are available with several different flow rates to accommodate baby's changing needs. Reusable bottle nipples and disposable nurser nipples are not interchangeable. |
