Ohhhh, I'm trying to think.... Amelie went to a ballerina party last year. I can't remember the food though. I do remember little milk jug things though... they were little glass jars (like baby food jar size) and they had little labels on them, I guess she made them herself, and they had strawberry milk, and little pink straws. They were adorable, and the kids loved them!
I know these aren't really ballerina themed, but if you put them in ballerina cups, they would work. lol. And you could put just normal fruit salad in them instead of just strawberries.
