DD just turned 11. She had permature adrenarche (when the adrenals kick in before puberty proper) which gave her some body hair v early, but at the time she had to have scans etc, and everything else was age appropriate. I started my periods very late (nearly 16) as did my mother (16), so I hoped it was all a few years away, but recently, e.g. in the last term, she has put weight on. She's always been very thin, at the bottom centile for weight, and although still a very slim girl, she is more padded than she has ever been, and her general body shape is changing. She also has the mood swings from hell......she is tallish for her age too. (4' 10")
I've talked to her about periods, she is well informed, but she is worrying about what will happen if she starts in school. I've suggested she tells a teacher but she thinks that is too embarrassing. I've also suggested that she has a little "emergency pack" in her bag, in case it happens in school but she was quite ambivalent about that. None of her friends have started or, look as though they might, so she is worrying about being the first and dealing with it at school and socially.
I remember reading that girls tend to start their periods when they hit a rough weight of 7 stone, is that true? It was true for me, but that may be coincidence! (she is five stone 5) I wondered if there were clues that periods might be likely to start, as I'm worried about her starting in school and getting in a state about it. I'm also really rather hoping that it is a couple of years away at least.
