Specially designed for your baby's first sips, our sippy cups help your baby to develop tipping and sipping skills whilst preventing spills. The easy to drink from trainer cup features a clever two-piece valve that allows liquid to flow easily through the spout when your baby wants to drink, but keeps the cup fully spill proof between sips. This cup also comes with a handy removable hygiene cover Featuring Intellivalve, a unique anti-leak technology which guarantees this trainer cup is completely leak-proof as it withstands internal pressure meaning the cup won't leak even when it is turned upside down or shaken. Our unique valve both seals and regulates the flow of liquid to stop leaks and to ensure easy drinking. With hygiene at the forefront of everyone's minds our drinking bottles add an extra layer of reassurance as the drinking spout contains Bacshield antibacterial technology. Bacshield is a commonly used silver-ion technology that provides antibacterial product protection against unwanted bacteria, recognised for centuries with no harmful effects. It works by preventing the growth of unwanted microbes that can cause product degradation, discoloration, staining or odour. This is achieved with silver ions mixed in the material on the spout*, preventing microbes from multiplying.
