A healthy solution for babies starting at 9 months old. The 360° spill free design virtually eliminates any messy clean-up and because there are no spouts and straws, the 360° EVEN-SEAL drinking edge provides a healthy alternative that helps toddlers develop the oral and motor coordination to transition into a regular open round cup sooner without the headache and frustration of dealing with spills and endless training sessions. In addition, the no-spout and no-straw design helps in the prevention of potential Orthodontia issues due to long term sucking on spouts. Ergonomic cup design provides a sturdy, easy-to-hold handle system for a safe, comfortable and natural gripping function for your baby. NEW Comfort Lip Edge allows your baby to drink easier and more naturally. Drink through gentle sucking without the need to press buttons, move levers, or sip on straws and spouts. Just pick up the cup and drink anywhere along the rim. After drinking, the valve automatically seals itself until you take another drink. The Wow Cup is spill free, worry free and hassle free!
