Like nails on a chalkboard

Did I mention Grayden grits his teeth? The running tally of teeth is now two on the bottom in the middle and one coming in on top. However, now that he realizes that he has somthing to grind against, he is now grindging his teeth all the time. Scott thinks it sounds like the creature from Preditor. I just think it gives me goose bumps. People have told me that it's really not a big deal and all babies will do it. I sure can't wait till he grows out of this phase.
