The uniquely designed Doidy cup features an ingenious slant that helps little ones learn to drink from a cup. The slanted shaped allows them to see what they're drinking without tilting their head forwards or down. It also helps them learn to put their cup down, so there should be fewer spills. Plus dental professionals suggest that training children to drink from a cup as soon as possible can cut down on the long term dental problems associated with prolonged use of bottles. Designed and made in the UK. Dishwasher topshelf and microwave safe. All our drinking equipment and feeding utensils comply with current European Standards BS EN 14350 and BS EN 14372
