Developed with Pediatric Feeding Specialists, the Evenflo Feeding Balance Plus Standard Neck Nipple is designed to support healthy bottle feeding without interfering with your breastfeeding journey. The unique, naturally-sloped nipple promotes a healthy wide latch for your baby by providing a proper resting place for their lips, helping to decrease mouth fatigue. The effective 1-piece integrated vent helps prevent colic, gas, and fussiness with no extra parts to clean or lose. The slower flow rate helps prevent chugging, allowing for a calm, gulp-free feeding at baby’s pace. The Balance Plus Standard Neck Nipple is compatible with the Balance Plus Standard Neck Bottle. The Evenflo Feeding Balance Plus Nipple is made with 100 percent soft silicone and is 100 percent free of BPA, polycarbonates, PVC and phthalates.
