What is the first sign of puberty in girls?

The first sign of puberty in girls is breast development. This initial change typically occurs around ages 8 to 13, marking the beginning of physical development associated with puberty. The development of breast buds is often the earliest visible indicator that a girl is entering puberty, signaling the body’s preparation for future reproductive functions.

Menstruation, while a significant milestone in puberty, usually occurs later in the developmental process, typically after breast development has started. Growth spurts do occur during puberty, but they usually follow the initial breast development phase. Body hair growth is also part of the overall changes during puberty, but it typically appears after breast development has begun.
