The Chicco NaturalFit 8 oz. 0m+ Slow Flow Bottle has a unique angled nipple that promotes ideal positioning for a perfect latch and bio-mimics the breast in form, feel and function, for a natural transition from mom to bottle.Form: The angle of the nipple makes the natural cuddle-cradle hold of breastfeeding the most comfortable way to use the bottle, setting you and baby up for success in a position that is both ideal for newborns and feels natural and comfortable for parents. Feel: Once you're in position, the supple, satin-textured silicone nipple and the soft, rounded, breast-like base feel familiar to baby for an intuitive latch. Function: A slow flow rate along with dual anti-colic valves, which allow the air inside the bottle to escape out the sides of the nipple, help prevent air ingestion so that baby swallows only the good stuff. Feeding your baby should be a time of bonding and relaxation for both you and your child, that's why Chicco designed the NaturalFit Bottles, to make bottle feeding as simple, relaxing and natural as breastfeeding. With an easy transition between breast and bottle, feeding time is always that special moment it was meant to be.
