Newton's First Law...
States:
Every object in motion tends to stay in motion.
All new mother's should be alerted to the fact that once they become a mother, they are in constant motion. And that motion will not stop... ever! I think I have been perpetually rocking, or shaking my knee, or swaying since the moment Kayla was born. And not just when I'm holding her. I often find myself swaying or whatnot when other people are holding her! It is a bit ridiculous! Oh well... maybe it's helping me burn off more of the 46 pounds I gained!! LOL!
