Derek lost his first tooth!  On our way to dropping him off from school, we were walking and all of a sudden Derek says "Look Daddy!  My tooth fell out!"  We headed immediately to the nurse's office, where we got a blue tooth case lanyard where he wore it around his neck.  As soon as I dropped him off to his class line, he was showing his tooth to all of his classmates.  He was very excited to show it off!
