Question: What is Puberty?
Answer: Puberty is the time when your body starts to change from a child's body into the body of an adult woman. Girls typically begin going through puberty between the ages of 9 to 13, while boys experience puberty a little latter between the ages of 10 to 14. This is why you might notice that you or other girls at your school are getting taller than the boys. Don't worry if you're one of the tall girls, the boys will catch up soon enough.
Although puberty sometimes seems a little scary, it's actually a good time that brings you more freedom and responsibility. You'll be able to make more decisions for yourself. Puberty means you are becoming emotionally and physically mature.
