Butt first...

While we were up house-sitting, Cam learned that he loves loves loves steps. Of which we have none in our house, except for the step down from the slider to the patio. Yesterday we let him practice going up and down steps, which he happily did for about 20 mins. Crawl out of the house, lifting knees off of the prickly welcome mat; crawl back into house, turn around, repeat :)
