This Philips AVENT My Natural Drinking Cup makes it easier for your toddler to transition from bottles and sippy cups to grown up drinking without the mess. This spoutless cup features a unique spill-proof valve that's lip activated. The cup allows drinking from all around the rim, just like an adult cup! This design encourages your toddler to get used to grown up drinking. This cup features a spill-proof valve that prevents waste and mess. The fast-flow valve is activated when a child's top lip presses against the lid, so milk or water only flows when your toddler is ready to drink! When the cup isn't in use, you won't have to worry about spills and messes, as it includes a separate hygienic lid to keep the cup and its contents clean, whether at home or on the go. To encourage independent drinking, this cup has special trainer handles toddlers can easily grip. Safe for toddlers, this cup is BPA-Free and is also dishwasher safe for easy cleanup and sterilization.
