Interested to hear how long it was between noticing first armpit hair and when the first period occured. I've just noticed very light armpit hair for my 9 year old daughter and faint BO. She has some very faint light pubic hair. I'm not really sure about breast buds but if they are there they are tiny. No discharge yet. When I Google puberty it seems that arm pit hair normally happens when the breasts are more developed?! I'll put a pad etc into her bag and she knows the basics but I don't want to freak her out by going into a lot of detail if nothing's going to happen yet. Her signs of puberty maybe seem not quite in the normal order?? Really hoping she doesn't get her periods yet.
