This pivotal stage of development is marked by significant growth and transformation, as she begins to assert her independence, explore her identity, and form meaningful relationships with others. With the onset of puberty, her body undergoes a series of dramatic changes, including the development of secondary sex characteristics, such as breast growth and the onset of menstruation.
