Crawling Up Stairs

Erin started crawling up the stairs a couple of weeks ago.  I snapped a couple of pictures when she was in action.  Just the other day, I was upstairs helping Emmy go potty on the potty chair and all of a sudden I heard the baby gate clanging away.  Erin had crawled all the way up to the top of the stairs (from the basement to the main level) which is about 6 or 7 steps.  As soon as I heard the clanging, I ran down to grab her.  She was so excited...I was more frantic.  I was excited for her, but worried at the same time.  I would hate for her to fall all the way down.  Yikes.
