Puberty when your body starts to change

Puberty is when a girls or boys body starts to change in preparation for adulthood. Puberty is different for everyone - different girls develop at different stages. There are a number of changes which will let you know that puberty has started for you, such as rapid growth in height and weight, developing breasts, pubic hair and pimples (bummer!). You can checkout a full list of the changes in our Female Puberty section.
