Here are your breast development stages: named after British pediatrician and professor JM Tanner. Doctors simply call it the Tanner-scale.
Do you worry that you develop too slow or maybe too fast?
Here is guide that might help to point you into a direction. Keep in mind that this is only a guide, everybody develops differently.
Like this girl, who started to develop in her early 20’s. Be patient!
Sometimes it might just takes TIME!! :)))
A little teaser: I was always very self conscience of my breasts, even before I figured out a reason WHY! I was also always a little on the chubbier side as well. When I was 14 I grew about 5" in a year to stand just over 5' 7" and then I gradually gained weight again. I always ate healthy and worked out but it was just hereditary to be a little larger, and have larger breasts. Well, I got older, and older and at 20 I was still a 36A and figured the only way I was going to have larger breasts was if I was ever pregnant. More here: Late Breast Development Story
Developing the actual full size of your breast will start anywhere from age 8 and when you are between 17-19.
Please note that the "age" indicates an average. This age can vary depending upon ethnic groups and genetics.
Stage 1: age 8-12: Nipple elevation only. This is a wide age range but we are all different. At first the only thing that will happen is that your nipple will stand out a bit.
Stage 2: age 13: About a year or so later, your breast bud will form. This stage is called "budding"; your areola (that’s the darker area around the nipple) will get a little bit larger.
Stage 3: age 14: Another year later, your breasts will start to get more elevated and your areola will widen further.
Stage 4: age15-16: Your breast size might stay unchanged, or get fuller. Also your breasts will begin to take shape.
Your nipple will stick out and might form a secondary mound.
Stage 5: age 17-19: Your breasts will get fuller and you will reach your final adult breast size.
