The Stage 2, Medium Flow Nipple is perfect for infants and formula feeding, and fits all Breastflow bottles.
The Breastflow System is ideal for nursing moms who would like to introduce a bottle, are returning to work, or need to supplement while their baby is in day care or with a caregiver. Because Breastflow bottles so closely mimic the feel and action of breastfeeding, care givers can bottle feed baby while Mom is working and Mom can still continue to breastfeed.
