This cup is a great tool when teaching your toddler to transition from a sippy cup, where they need to turn the cup up to drink, to using a straw and drinking out of an open top cup. The soft plastic will not hurt their teeth like hard plastic. It will help your baby learn to sip rather than suck and is a natural fit for little hands and easy to hold. 

Features:

Suitable for cold drinks, fruit juice, milk, and etc.
