Babies six months or older obviously require much more sustenance than they did just a few months earlier. Fast-flow Comotomo nipples are equipped with three holes to facilitate feeding needs, allowing baby to feel more fully satisfied at a quicker rate than our medium flow nipples. Our silicone nipples most closely resemble mom in both feel and shape; making the transition from breast to bottle an easy and enjoyable one for both mother and child.åÊ
