Mere beti Riyanshi ki under arm aur ek do pubic hair ayi hai kya ye common he ya phir kuch problem hai. please answer

A. Generally when you start saying pubic hair or under arm hair it is a sign for puberty basically it is going to reach puberty soon and your child is seven years old I am a very certain is it because of puberty but you should get it checked with your doctor because girls are hitting their property at the age of 8 to 9 years also
