My boobs aren't growing fast enough - help! It's especially embarrassing when I have to change in the locker room for basketball practice.

One of the wildest things about puberty is that it varies a lot from person to person. You know you can start driving at 16 (in most places), but when are your breasts supposed to start growing? The answer is that breasts can start growing as early as age 8 or as late as 13.
Some girls' breasts grow slowly and others grow quickly. Some girls may feel like their breasts will never start growing. But it's just that girls start developing at different ages and different rates. One girl might have more developed breasts at 12, whereas her friend could be still flat as a board.
So hang in there, it will happen. Since you're not wearing a bra yet, why not start? You may feel more comfortable with your bra on board, especially for those locker room moments!
