Between the ages of 8 and 18, your body starts growing and changing, due to an increase or change in hormones. In girls, the main hormone guiding the body's changes is called estrogen. In boys, it's testosterone. This period in your life is called "puberty." There is no exact age when everyone experiences puberty - it differs from person to person. Girls usually experience it between the ages of 8 and 17. Boys can expect puberty between the ages of 10 and 18.

Puberty is a time when there are huge changes in your body. At the same time, your feelings also change dramatically. It is quite natural that you may feel differently about your family, friends and classmates. Boys don't go "yuck" when they see girls! And for the girls, boys don't appear creatures from outer space! In other words you will experience a whole lot of "social" and "behavioural" changes. This can get a bit confusing, but don't worry, it's absolutely NORMAL!
