Baby Bottles with NaturalWave Nipple (5oz)
Our soft, flexible, 100% silicone bottle nipples have a textured base and triangle shape to make it easier for babies to latch and control the flow of milk while feeding. Our baby bottle also includes an anti-colic vent that minimizes air intake to help prevent gas, fussiness, and spit up for smoother, more harmonious feedings.
