Puberty is when children’s bodies slowly turn into grown-ups bodies. They get bigger, but they change too.
This period is called adolescence. For girls, it starts around 10, whereas for boys, it’s a bit later, around 12.
It’s a slow transformation caused by hormones, a molecule produced in the body. Generally, puberty lasts 3 to 5 years.
