The first period is one of the topics girls and parents think about most. When a child knows what to expect, she feels more confident.
When does puberty start in girls?
According to the NHS, puberty can start at any point between about 8 and 14[1]. In girls the changes include breast development and the start of periods, as well as pubic and underarm hair[1].
When does the first period come?
The NHS says most girls start their periods at around 12, but they can start as early as 8[2].
What is normal at first
