Packing: A Toddler's Viewpoint

I have started the process of packing up boxes for the move. However, as you can probably imagine, this is not easily accomplished with a 13 month old in the house! He either unpacks the boxes as I pack them, or climbs in or on the boxes! (Yes, by the way, he has starting CLIMBING! Yikes!) I could very easily become frustrated by this "one step forward, two steps backward" approach, but seriously, how can you get mad at THAT face?!
