This two-pack of Dr. Brown's spill-proof sippy straw bottles with handles helps babies 6 months and up develop new drinking skills. The bottles feature a soft, 100% silicone weighted straw that moves with the liquid, enabling babies to tilt and sip from any angle. Sturdy yet soft silicone handles promote motor skill development and make gripping easy. Spill-proof lids slide closed to keep straws clean. Both bottles hold 8 oz/250 mL and fit all Dr. Brown's narrow-neck baby bottles and sippy cups. The removable parts are dishwasher and sterilizer safe for easy cleaning. With complementary colors and features, these bottles transition babies beyond traditional bottle feeding while allowing them to continue using the Dr. Brown's bottles they know and love.
