Each Vital Baby HYDRATE little sipper has an easy drink super soft silicone spout, so it is safe and gentle on baby’s gums, as they build confidence and practice how to drink. The one piece silicone spout which has an integrated non-spill valve, is easily removed for thorough cleaning. The non-spill valve helps to ensure that their drink will stay in the cup until they drink it! A flip closed hygiene cover helps to keep the spout clean.For Best ResultsWash before first use and after each use. Top rack dishwasher safe (max 65°C).
