Most girls start their periods when they're about 12 years old, but they can begin as early as 8. The average age for puberty to start in girls is 11, but it can occur earlier or later. The period usually starts around the time a girl begins puberty. It is a natural part of growing up and becoming a woman.
It's important to talk to girls from an early age about periods to make sure they are informed and prepared. They can learn about what to expect, how to manage their periods, and what resources are available to them.
