Balancing

Have you ever considered how difficult it is to pick something up off the floor from the standing position (without crouching or bending your knees) and straighten back up? I was contemplating exactly that today as I watched BB lean over, pick up a toy and successfully stand back up into vertical. For someone who has an underdeveloped sense of balance, it must be a difficult thing for as many times as I hear her falling everyday. Naturally, she has neither far to lean over nor far to fall, but it was clear even to her what she accomplished today.
