Sip and tip in any direction! Dr. Brown?s? Baby?s First Straw Cup simplifies the bottle to cup transition for you and baby. Designed with a soft, weighted straw, baby can drink from any angle ? helping them transition from tipping the cup upside-down to sipping upright. Baby?s First Straw Cup features handles that lock in place to make it easy for little hands to hold. The cup is contoured, and the handles are removable, so it grows with baby as their cup holding skills improve. The travel-friendly lid slides open when baby drinks and keeps the straw clean when not in use ? plus it?s spill-proof! Comes in bright blue, pink, purple, and green colors with cute animal faces that baby will love. All parts are removable for easy cleaning and preventing dirt build-up. Dishwasher (top rack) safe. Electric sterilizer and boiling safe. Do not put in microwave. Straw cleaning brush included. 9 oz/270 ml. BPA free. 6m+.
