Harriet did not nap today.  I could hear her bouncing and singing, but not napping.  When I went in to get her I entered her room and gave her a hug.  The first thing that she said to me was, "I'm a little sweaty cuz I was exercising."  I laughed at that and said that she was supposed to be sleeping, not exercising.  She responded, "I was!  I was exer-sleeping.  That's sleeping and exercising at the same time."
