When your little one turns one, it’s usually time to consider weaning them from the bottle and sippy cup to an open cup. They might at first find that drinking from an open cup is difficult and that’s why we developed our 360 cup. It’s leak-resistant and break-resistant, and your young child is able to drink from all sides. If your toddler still prefers their sippy cup or refuses to drink from an open cup, then you could try giving them a water bottle or a straw cup instead.
