Lily's funny new trick

I'm out in Baltimore for a little visit and am highly amused by one of Lily's latest tricks. When she's in a sitting position and wants to get into a rolling or crawling position she just leans forward and THWAP! clunks her head on the floor. Now, while they may have nicely padded rooms at school, the only thing on the floors here is a pretty thin rug. This results in a nice red circle wherever her head came into contact. I should mention this doesn't seem to phase Lily in the slightest. She just goes on with her business.

It's a little hard to see in the picture, but if you look closely you can see the red spot above her right eye.
