Pubarche is when your private parts start to grow hair! When you were born, you didn't have any hair there, but as you grow up you will start to notice some hair growing. This usually happens when you are between 8 and 13 years old. It's a normal part of growing up and becoming a big kid! Just like how you grew taller and started to get bigger muscles, your body is also growing hair in new places. It's important to remember that everyone grows at their own pace and there is no right or wrong time for pubarche to happen. As you get older, you will learn how to take care of your body and keep it healthy and happy!
