Happy Anniversary to us! And pics of Dorothy

So we've finally hit the big two year mark--we decided this is our "Sandstone Anniversary" (we're not real sure what the rock hierarchy is, so we're just making it up). But you guys don't really care about that--you want Dorothy photos! So, without more ado, here is Dorothy hanging out on the floor and starting to sit-up on her own (though about two pictures later, she almost did a head dive right off the couch).
