So before DC I was a 32E (all fitted at Bravissimo so no dodgy fitting advise). During pregnancy stayed at 32 but went down to 30 
afterwards (can't remember cup sizes).
After having DS, stopped BF and measured 30FF expecting this to go down over time. Sixteen months later and my bras are too small and according to the Bra Intervention thread I should now be wearing a 30GG/H 
.
Any explanations as to strange boob growth? I don't know if it's related but up until recently I could still squeeze a tiny bit of milk out but it finally seems to have stopped.
