Not necessarily: The average age in the US is 9-13, but some girls do start earlier. Most girls start their periods about 2 years after breast development starts. It is also possible for a girl to have a period, and then not have another one for several months. It takes about 2 years before they become regulated. If you have any concerns, check with her doctor.

Yes that is early: That is early, the median age of the start of menstruation is around 12.5 years old. But your girl might be an early bloomer. You could visit the pediatrician just to let them know that menstruation has started. But there is nothing inherently bad about this. She just needs guidance now that she has entered this phase of her life. I am sure you will be able to guide her during this new change
