OCV - Obsessive Compulsive Vanessa

At first I was just amused with Vanessa, but now I am even more amused. Lately I have seen a particular type of behavior become even more compulsive. There is this little dent in our wall in our our dining room. It's just big enough to put the tip of a baby's fingertip in it. It started off with just a curiosity that all children innately have. Vanessa and Natalie would poke and prode every now and then because it was just a new concept to them. Then Fiona and I noticed that over the past week Vanessa would just get up, walk towards it, put her finger in it, and then just walk away. She's done this probably a half dozen times. Well yesterday I got to see her obsession hit another level. I was in the t.v. room and I noticed her walking over towards the dining room. There was a high chair in front of the area of the dent (but not completely blocking it), and Jadon's little tykes car that was also in the way. Vanessa was carefully maneuvering around the car (moving sideways between the narrow space between the car and the high chair). Then she bends down into a crawl position to crawl undernearth a portion of her high chair and gets up on the other side. She succeeds and continues to touch the dent and then crawl backs out from the high chair and walks back to the t.v. room. Weirdo......
