It used to be that, when I saw Benjamin lying down on the floor to play like this, I thought, "Aww, he must be tired."
But then, the evidence forced me to change my hypothesis.
You see, Benjamin does this very often. Multiple times a day. So either he's a one-year-old sufferer from Chronic Fatigue Syndrome, or there's another reason for his actions. ;-)
I'm going with the latter option. ;-)
And I also think, "He is absolutely adorable, and I love him more every single day."
