Developed with Pediatric Feeding Specialists, the Evenflo Balance Plus Standard Neck 2 Ounce Baby Bottle is the perfect size for baby’s first bottle. With a more naturally sloped nipple shape, these bottles provide a healthy latch with a proper resting place for lips, decreasing mouth fatigue. The nipple shape also encourages tongue cupping, similar to how baby would latch at breast. A suitable flow for preemies, the Balance Plus Standard Neck Baby Bottle Nipple is designed to have a slower, more comfortable flow ensuring a more relaxed drinking pace for baby, without the need to gulp to keep up. The naturally sloped nipple is also designed with a just right nipple length, stimulating the soft palate which triggers baby’s natural sucking reflex. Evenflo’s patented Proflo™ Venting Technology ensures milk bubbles stay in the bottle and not in baby’s tummy, keeping your baby comfortable even after they are finished eating. This integrated, 1-piece venting system helps prevent colic, reflux, gas, and fussiness with no extra parts and pieces to clean or lose. Want to pump directly into your Balance Plus Standard Neck Baby Bottle? These bottles easily attach to most standard neck breast pumps, helping you save time by simplifying the pumping process. To help take the guesswork out of feeding your little one, the Evenflo Balance Plus Standard Neck Bottles have molded measurement markers in both ounces and milliliters to provide an easy and accurate way to measure the volume of liquids. All Evenflo bottles and nipples are 100% free of BPA, polycarbonates, PVC and phthalates, and are also made of FDA approved food grade material.
