Creepy Crawler

We officially have a crawler now. For about a week, she's been crawling some, mostly only when there is something that she REALLY wanted to get her hands on (like pieces to the kids' puzzles--she loves those more than any toy). Then yesterday, I noticed she was actually crawling from one side of the living room to the other, not after anything in particular, but just because she could. But she was still staying within one room. Well, not anymore. Today, she has discovered that she can put this crawling thing to good use and really get around the house. She is now leaving rooms and hiding behind the couch...and boy are we in trouble! And I'll be forced to keep the house more clean now, so that will be good too!
