Oh No!!

So I picked up Zoe from daycare on Friday and her teacher says "Do you want to hear a funny thing that Zoe did today?" and she proceeds to tell me that Zoe pulled down her pants, took off her diaper and then peed on the floor!! I was so shocked!! I have no idea why she did this! We thought maybe she wanted attention and Corey says that he bets they will pay attention to her now!! I just can't believe it, I have not a clue how to go about handling this. My guess is to put her in pull ups and have them take her to the potty often. Any other thoughts??
