Development of Breasts
You can't do anything to make your body develop faster. Of course, you should eat a nutritious diet, exercise, and get enough sleep. But special diets, dietary supplements, or creams won't do anything to make breasts to develop quicker.
The earliest physical change of breats for girls is usually around 10 or 11 years. But it's perfectly normal for breast development to start anytime between the ages of 7 and 13.
