Dr. Zhang Weiling
Development beginning at age nine is normal for girls but indicates precocious puberty in boys, which is abnormal. In girls, normal breast development typically starts between ages 9 and 10. Breast development is the earliest sign of female puberty; in a small minority of cases, pubic hair development may precede it. Breast development usually begins between ages 9 and 10, often starting on one side, with the other side developing several months later.
