9 when I started developing breasts ( i was so embarrassed because pimples came with it)
11 when I got AF.

My friend (single father) was so embarassed the other day asking if his 7 year old was normal. I said "what do you mean by normal?". With much hesitation he said "she REALY needs a bra and asked what the hair 'down there' was". I was a little shocked (SEVEN?!?!)
