Mommy Hands?!?

Okay, so Rach likes to see the changes in my pregnant body. Why, I have no idea, but the other night she looked at me and said that I'm getting, and she loves my "mommy hands". Mommy hands? What are mommy hands and how in the world do they differ from regular female hands? Granted, when I first got pregnant she said my hands got much softer, which I noticed too, but an actual change in the look of my hands? Hummm...Mommy hands.
