This 6-pack bundle of Dr. Brown's bottle nipples and sippy bottle starter kit is designed to support your baby's feeding needs as they grow from 6 months and beyond. The nipples feature Dr. Brown's clinically proven Anti-Colic vent system to reduce colic, spit up, burping and gas. The Medium-Fast Flow Level 3 nipples provide a vacuum-free, consistent flow rate to mimic breastfeeding. The breast-like nipple shape encourages proper latching. Transition your baby from bottle to sippy cup using the included 8oz sippy bottle. Simply replace the familiar Dr. Brown's bottle nipple with the soft 100% silicone sippy spout. The snap-on cap keeps the spout clean on-the-go. Both the nipples and sippy spout are dishwasher safe. With the Anti-Colic bottles helping reduce feeding issues and the sippy kit for teaching new drinking skills, this bundle conveniently provides solutions for your growing baby's needs.
