Nothing is quite so precious to the parent’s soul as seeing a tiny, white tooth in a tiny porcelain heart-shaped box under a pillow. It is just about the most delightful sight in the world. Of all the important things, all the world-changing things, I cannot think of a sight that is more rich and fleeting at the same time. It is one instant, that will soon be over. The child is going to be grown before you know it.
