The average age for girls to begin puberty, marked by the development of breast buds, typically falls around 10 years. This is considered the average onset of puberty within a range that can vary widely among individuals.

The onset of breast development is one of the first observable signs of puberty in girls and is a critical milestone in their physical development. Puberty usually begins between the ages of 8 and 13, and while 10 years is the average, individual factors such as genetics, nutrition, and overall health can influence the exact timing of this developmental stage.

Understanding the average age and recognizing that individual experiences may vary is important in pediatric nursing, as it allows professionals to better assess and support each child's unique growth and development journey.
