Hi My 7/6 year old daughter has grown hair in her armpit .Is it normal for it to come so early?

A. Mam it’s very very early let me tell you that also I would like to tell you two things over here when you see her coming in the vagina region and under arm it’s actually a sign of puberty but right now it is coming in under arm but not in pubic region so it’s a good thing that it’s not a sign of puberty but having hair and under arm in this small age is not good
