Nipple Sizing Information
You can choose from four flow sizes depending on your baby’s age and desired feeding routine:
Slow Flow (0-3 Months)
Medium Flow (3-6 Months)
Fast Flow (6+ Months)
Fastest Flow (6+ Months and Thicker Liquids)
Doctors recommend using the slowest flowing nipple your baby will accept to help reduce gas and colic. The months listed next to each nipple sizes are just meant as guidelines. To learn more about when your child is ready to take a faster flowing nipple, check out our post on nipple and bottle sizes here: "What Size Bottles Do I Need for My Baby?"
