The Dr. Brown's bottle and sippy cup bundle is the perfect pair for transitioning baby from bottle to cup. The bundle includes two 9oz Dr. Brown's Options+ wide-neck bottles with level 3 medium-fast flow nipples, ideal for babies 6 months and up. It also includes a set of soft silicone sippy spouts and snap-on caps that can replace the nipples, converting the familiar bottles into sippy cups. As baby's feeding skills progress, the sippy spouts allow them to learn new drinking techniques. The Dr. Brown's bottles feature a clinically-proven internal vent system that reduces colic by decreasing spit-up, burping, and gas. The vent creates a vacuum-free feeding experience closest to breastfeeding. The breast-like nipple shape and medium flow rate allow baby to feed comfortably at their own pace. All parts are made from soft, 100% silicone. The included level 2 nipples provide the next flow rate for growing babies around 3 months and up. The consistent medium flow is designed specifically to aid the transition between breast and bottle feeding. Together, the Dr. Brown's bottles and nipples deliver an anti-colic feeding system to reduce fussiness and discomfort. Parents can feel confident that baby is getting a high-quality feeding experience that helps preserve nutrients and supports healthy digestion.
