Jeannie, you'll want to pay special attention to this story; you play a pivotal role! ;)
Sarah has a toy shopping cart and several cardboard boxes of "food." Today, she brought all of her food boxes into the living room, along with her pretend money. She set up all the groceries on the table and handed me the money. "Mommy, you've got to buy my groceries! I need them for Grandma!" We went through this several times, until I had bought all of her groceries. She then loaded them into her cart and headed for her bedroom saying, "I've got to go get ready! Grandma's coming for the party!"
So she set up all the food for a lovely party with Grandma. Tell me, Jeannie, was she a good hostess? ;)
