My 8.5 year old daughter has small armpit hair and small hair in private parts. How long till she gets her first period??

A. At least a minimum of half a year that you can expect to entire one year I’m not very certain about it but because when you see in grown in both the areas it is not a good sign in an early age this is the child period it’s not at all good because it is going to lead to r improper height improper a lot of things would be affected please check with your doctor regarding this
