Most moms agree the less time spent on the trial & error process of finding the right bottle, the better! But did you know that your baby might be rejecting the nipple rather than the bottle? Try a wide range of 4 nipples in different shapes and sizes to match your baby's unique preferences. Wide raised textured area is designed to promote proper latch-on for easy switching between breast and bottle. All Playtex nipples are BPA-free and compatible with all Playtex bottles.
