It's hard to say - anything from 8 years old can be considered normal, and in very rare cases girls as young as 3 years old have started to menstruate. There may well be cases in earlier history or in less economically developed countries of much younger girls reaching menarche, without us knowing about it.
It is normal to start your period from the age of 11 - 16but the youngest girl to start her period was about 3 but that is EXTREMELY rarei was 13 :)hope this helps x

The youngest mother to give birth was a 5 year old from Peru. She gave birth in 1939 via cesarean section. She was taken to the hospital when she was though to have a tumor in her stomach when it was discovered that she was 7 months pregnant. It was then learned that she was a victim of child-sex-abuse.
Any age at which a woman can conceive a child...so between the time you start your period and menopause.
Numerous websites cite Sean Stewart from Sharnbrook in England, age 12 when the child was born, age 11 when he fathered the child and the youngest documented father. There was one article that stated a 6 year old boy in China was the youngest, but does not specify a name or another other documentable source. The youngest father on record is Joel Bailey of England, whose child was born in 1998. Bailey was eleven when the child was conceived and twelve when the child was born.

You start boot camp at whatever age you join the military. Seventeen is the youngest that you can start (and you need parental permission).
