can you tell me where you found the cinderella cup
we currently use these
My son loves them
I ordered them from allaboardtoys.com
It is a Disney Princess Meal Mates 10 oz soft spout cup
Click on the Disney Princess catagory and then click on Disney Princess Dinnerware (its a picture of a fork and spoon with Princesses on them). That will take you to the page and scroll down toward the bottom. Its a purple cup and it is $3.57. Shipping is a flat $5.95. I ordered 2 of them and hope that they will be good.
My son just wouldn't/couldn't do a sippy cup, but he took to the spillproof straw type very well. Speech therapists tell me that the straw type are actually better for the child for speech development so that was an unintentional bonus for me.
