Dr. Brown's Milestones Straw to 360° Cup Set, Convertible Toddler Training Cup Set with Interchangeable Silicone Straw and 360 Degree Cup Lids, Blue Green, 10 oz/300 mL, BPA Free, 9m+, 2 Pack

The all-in-one set to help baby transition to straw and big kid sipping. Dr. Brown's Straw to 360° Cup Set includes a lid with super soft silicone straw to help baby develop new straw-sipping skills. The silicone is gentle on baby's sensitive mouth and is spill-proof! Then when baby is ready, switch to the Cheers 360 sippy cup lid. The 360-degree design lets baby drink from any edge, and the Sip and See clear silicone valve lets baby see inside without spilling for true leak-free learning. The Cheers 360 lid features handles that are easy for little hands to grasp and tilt while developing independent drinking skills. The cup is translucent so you can see when it's time for a refill, and the easy to assemble three-piece design is dishwasher (top rack) and sterilizer safe for easy cleaning.
