When did that happen?

Our Baby K is starting to try to walk! She pulls herself up on all the furniture and will let go with both hands to balance herself for a few seconds. She also has a baby walker that she has become quite proficient at using. It seems I'm about to have a toddler on my hands! The funniest thing is that I'm not really even sure how she learned to do all this. Only about three weeks ago we were worried because she wasn't showing much interest in crawling. But now she is crawling on her hands and knees like a pro and using the furniture to move around the room.
