DS1 I only BF'ed for a short time. My boobs were large B/small C pre-pregnancy. During pregnancy and BF'ing they became large Ds. They never went back down.
DS2 my cup size didn't change at all during pregnancy. They went up a little bit ( D/DD dependng on brand) while BF'ing. We haven't weaned yet, so I don't know what will happen then.
I'm a STM, my boobs went from 36B to 38DD with breastfeeding my first, and after weaning, they went back to 36B. oh well, didn't keep the gorgeous boobs..
