My own breasts only started growing when I was 13 and they never developed into a full bosom. I ended up an A-cup with constricted breasts (which ended up sagging completely after my first pregnancy). Our elder daughter is 12 1/2 and still has no sign of breast development, the younger (11) started developing a year ago, which felt like a relief, but so far she only grew large and puffy areolas, as I did when I was 13. My mother told me my grand-ma had breasts like mine and I know that both of my cousins on her side have the same condition. Will I pass it over to my daughters or will it skip another generation?
there is a good chance she will have similar breasts as you mom..
do you have large areola & nipples, she may follow you in this area also..
