Your breasts may feel tender, sore, or uncomfortable during puberty. Your nipples may easily get sore, especially if you’re not yet wearing a bra. These differences will eventually fad out, and your breasts won't feel as tender.

Your breasts may give out a little bit of milk as they're growing, don’t worry this is perfectly normal. Your breasts are preparing themselves to do the function that they were made for; breast feeding.

One breast might develop faster than the other. Your breast may each grow at a different rate, but they will eventually even out, although it is normal for one breast to be slightly larger than the other.

Sometimes others may tease you about your breast, unfortunately this is normal. Most of the time they don’t mean anything by it, and don’t realize just how much it bothers you. Often if you calmly let them know that you don’t like being teased, then they will usually stop.

Because your breasts are new, and not everyone will get them at the same time, they may get a lot of attention. Keep in mind that everyone's breasts are different, no matter their shape or size, your breast are a unique part of you.
