...actually, we call her Mr. Monk. Rachel is a bit OCD (wants her hands wiped, has to touch things as she walks along). But she doesn't neccessarily have to line things up. Rather, she stacks them. So that's okay, right? Just nod your head and say, "right." It makes me feel better.
Be not a couch potato in our house! You'll soon find yourself buried under every toy Rachel owns! She's just keeping track, really.
