Hi, My DD who is 9 and 9 months has just got her first period. she has been developing quite noticeably over the past year or so...spots, hair, moods, the start of breasts and shooting up in height so it wasn't completely unexpected. She is fairly cool about the whole thing..we have talked about it and read books and all that, but can someone reassure me that she is not too young? Mine didn't start until I was 11 and I remember being one of the first in the class at school then. I know no one else in her class has reached these stages. Thanks
