Is something wrong with her to make her boobs big?

My girlfriend has the biggest boobs in our grade and the next grade normally I'd be happy : ) but she is worried if somethings wrong with her is that true?

How old is she?...But then maybe thats just her genetics (and puberty setting in) and not anything serious

There is nothing wrong with your girlfriend. It was just the way God made her. She has to accept the way she is. Doesn't matter whether her breasts are the smallest or biggest, that does not dictate who she is and the kind of person she is.

dont worry theres nothing wrong with her!
everyone has different sized boobs, your girlfreind just happens to have really big ones
but its completely normal
and also thanks to genetics and going through puberty
however if they cause her back pain, or making her feel uncomfortable then she could always have a breats reduction
but theres nothing wrong with them!

modernwinterbreeze is 100% right. Absolutely nothing is wrong with her. She gets it from someone in her family most likely. I have bigger (lets say sisters) but they aren`t the biggest in the grade and I have lots of true friends, and people treat me the way they treat anyone else. As long as she is not getting teased or put down just for the size of the twins, she is perfectly normal and she mature faster than others. SO WHAT!! She can`t speed it up or slow it down.

Tell her that is the way her body is and that she will have guys chasing her around for the girls. She can even give hem both a name. Tell her to feel more confident about herself
