Why does my 7 year old have hair n her vagina is that normal?

It's normal for children, including 7-year-olds, to start developing pubic hair as they approach puberty, which typically begins between ages 8 and 13. This hair growth is a sign of hormonal changes in the body. However, if you're concerned about early development or any other symptoms, it's best to consult a pediatrician for personalized advice and reassurance.
