I am a DD (before, during, after pregnancy, through nursing and after... no change at all) and had plentiful supply....
...and so have my friends who are As or AAs.
A friend who is a full C produced 4 oz a day at best. Needless to say, her baby is formula fed.
Has nothing to do with your breast size :) It does seem to be linked, however, to how much you sweat... I sweat a ton and so do all my friends who had plentiful supply... my friend who had no milk NEVER sweats. I've heard that the same hormone that produces sweat helps produce milk so if you sweat a lot, that's a good sign!
