The angled spout is designed to help toddlers take their first sips easily without tilting their head back too much. Soft touch trainer handles for little hands. Trainer handles help your toddler to hold the cup and drink independently. These handles are not only shaped for little hands to grap easily, they are also rubberized for a non-slip grip. The new Philips Avent cup is compatible with the Philips Avent Natural and Classic+ bottle range (excluding the glass bottle), and all other Philips Avent cup (excluding the Natural Drinking Cup).
