Oh how bittersweet! My boy is only eight, so I have a few more years for that, but I have an almost thirteen year old daughter. In the past two years she's gotten her period, started shaving her legs, asked me how to use tampons (!), and often stays up later than I do. She is 5 foot 2 inches tall (did I mention that I'm only 5'3"?!) and weighs 110 pounds. She is gorgeous, sweet, kind, caring, and can also be a total brat - as I'm sure you other mothers of teenagers can understand! YIKES!
