My daughter is now 13 and she hasnt grown in 6 months not even a cm. She says she thinks she started her growth spurt when she was almost 11 just a few months away from it. She is now 5'4 and noticed some of her friends who are her height has grown a little. She has started her period when she was 11 in a half. Im not really sure what her height was then though. Has she stopped growing
