The First Years Breastflow Disposable Bottle, 4 Ounce (Discontinued by Manufacturer)

The First Years Breastflow nipple is perfect for breastfed babies. It is the only bottle nipple that features a nipple-within-nipple structure that stimuates the breastfeeding motions of suction and compression enabling baby to go back and forth between breast and bottle more easily. Breastflow is available as part of The First Years Disposble Bottle System and works with Ziploc Brand Disposable Bottle Liners and other bottle liners.
