Kids can operate on their own with easy grip handles & volume markings so you know how much baby is drinking. Dishwasher & sterilizer safe. LEAK PROOF & SPILL PROOF: Our unique two way valve ensures easy drinking with no leaks or spills, even when the cup is on its side! And the flip top lid clicks into place to keep the straw clean on the go. TIPS FOR USE: If child is having difficulty drinking from the straw, ensure they place their lips over the whole straw (not just the tip) to press, sip, and let liquid flow.
