I am 12 and have size 36B bra and my best friend make fun of me because of that. Also one of the girls that go to school asked me if I stuffed my bra .I am bigger than all of my friend's. I don't know what to do.

Please give me advice.

Don't worry about it. It is normal. By the way a slightly larger breast makes any woman more attractive

One girl has to be the one with the largest breast. Girls develop at different ages, all of them will start getting them over the next couple years. They are jealous and all wish they had them, is why they make fun.

I'm sorry to say that this is one of the most difficult ages for people your age. Girls will tease you out of jealousy, boys will tease you because they like you! Try your best to ignore them or politely ask them to stop. If they're comments become rude (or worse) make sure you tell an adult.
You cannot help how quickly you develop any more than they can help the fact that they haven't yet.
Some of those girls are surely getting teased because they're "flat chested"... at some point everyone gets bullied. I'm sorry you have to go through it but it will make you a stronger person. Hang in there!

I'm sorry you're going through this. I went through this in 6th grade. I was the first one too. There are basically one of three ways you can handle this.

(1) You can hold your head up high and ignore them and be proud of yourself. If you were all older this would be the perfect way to deal with it. But at your age if you do this others will probably think that you're a snob.

(2) Hang your head and be ashamed. Wrong way to deal with this. I know that at your age everyone wants to be just like everyone else and no one wants to be different. But you should never be ashamed of yourself for being different.

(3) Laugh it off like they're making a joke. This is the best way to deal with it. Even if you feel embarrassed, smile and laugh. When they discover they're not making you feel bad they'll lose interest in trying.

It's going to be difficult. But the teasing will end and eventually it will be replaced by jealousy. You just have to get through the rough time and laughing at it really is the best way to do it.

Just one more thing... if anyone tries to touch you shut them down and immediately tell an adult!

Hang in there and good luck!

Don't Look At It As A Bad Thing. It's Normal. And A Lot Of Girls Get Fake Boobs. So On The Contrary. Congratulations (;
