Match the nipple to your baby's bottle and stage. Dr. Brown's wide-neck silicone nipples include the Y-cut for thicker feeds, and their Natural line covers standard feeding. Philips Avent offers anti-colic nipples in staged flows — like Flow 1 for newborns — plus Classic fast-flow and Natural Response nipples that let babies control the pace. Replace nipples every two to three months or at the first sign of wear. Orders over $50 ship free.
