How old are you when your breasts start to develop? My best friend is already starting to show, but I have nothing yet.

Breast development is an early sign of puberty in girls and usually happens between the ages of 10 and 11. However, if you start to develop a few years earlier or a few years later that is still considered perfectly normal. Our bodies are all different and develop at different rates, so it is certainly not any kind of immediate cause for concern if you see that a friend has started to develop before you. TeenHealthFX can appreciate that it can make some girls feel left out when they are not developing as early as some of their peers, but it doesn’t mean that there is automatically some kind of medical problem.

If you have any questions or concerns related to puberty or your own body development, FX recommends you speak to your doctor. For more information you can also read the TeensHealth article When Will I Start Developing?

If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center. You can also contact your insurance company for a list of in-network providers.
