Should I sterilize nfant® baby nipples before using?

If your nipples came as part of the Thrive Bottle kit: Yes. We advise sterilizing your nfant® Control Flow nipples before the first use. You can sterilize the nipples by placing them in boiling water for 5 minutes. Allow to cool and dry completely before using. Our nfant® nipples are dishwasher safe on the top rack only.

If your nipples were purchased in a 4 or 50 pack: If the nipples are still sealed in their original packaging, contents are clean and ready to use if the bag is not damaged or open. Once used, refer to instructions above.
