Normal puberty in girls typically begins between the ages of 9 and 12 years. Some girls may start slightly earlier—around age 9—while others may begin slightly later—around age 12. Puberty occurring significantly earlier than this may indicate precocious puberty. As puberty begins, various physical changes occur, including breast tenderness and gradual enlargement, the onset of pubic hair growth, and the eventual onset of menarche (first menstrual period).
