hello, my baby is 6.6 years old now and she is having some armpit hair and it's smelly also. Is this early puberty but in this age it's too early. what should I do?

A. It’s happening with kids these days at the age of seven and eight also so of course it is extremely unhealthy first of all to have hair in an early age and second is vagina hair also breast and husband then it is a sign of puberty otherwise not but having under arm in a small time is not good
