Playing in a box

Isaac and Elise decided to play in a box we got from FedEx last week. I'm not sure why their faces are so dirty, but this is normal for us. ;) It's probably a combination of syrup, juice and sidewalk chalk... or something similar. I do wipe their faces, but getting these pictures was far more important to me! Also, notice the peace sign stamps on their hands - the stamp was included in Isaac's preschool Valentine treat bag. He loved stamping everyone's hand! His sister's especially!
