The development of breast buds is recognized as one of the first signs of puberty in girls because it typically occurs early in the process of sexual maturation. This physical change is part of a series of hormonal changes that signal the onset of puberty, generally occurring between the ages of 8 and 13. The development of breast buds reflects the effects of estrogen and is an important indicator of the body's preparation for potential future reproductive capabilities.

While menstruation is a later sign of puberty and marks the ability to conceive, it typically occurs several years after the initial changes, including breast development. The height spurt and the development of pubic hair also occur during puberty, but they are usually seen after the onset of breast development. Understanding the timing of these physical changes is essential for recognizing normal growth patterns and addressing any concerns regarding adolescent development.
