It's all about genetics. You haven't started developing yet because your mom and grandma probably didn't start developing until they were older. Don't worry about it though. Your breasts will develop in no time.
Showing them to everyone. Air is the key to getting them to grow, they need oxygen too!
Since you haven't started your period, then, you haven't reached puberty and I doubt you really have breasts yet. To have breasts you need to have reached puberty because it is the hormones that your body uses to develop breasts. I am guessing you are feeling fatty tissue which is perfectly normal. Go to see a doctor just to be sure.
It is appropriate to wear bras as soon as your breasts develope to a point when they need support. Bras are not for vulgar purposes; unless they are specifically made for such things, they are only to support your body parts. I started wearing them around the age of ten or eleven.
depends on when you started puberty.

You should be able to see them. If you aren't sure, your breasts probably haven't started growing.
Yes (:
Maybe it is because you are growing in stages. First your period, then your breasts.
You are probably running a little late in that area. Or your body is not ready yet. Don't worry, some girls get there first period when they are 18! You have a while until your breasts fully develope. You're time will come!!!! Be patient, everyone's different. Even if they are in your family
If you haven't got boobs it might be because your late starting puberty normally when you get boobs it's a sign of puberty.
