hmm well I have been breastfeeding or pregnant for the last almost 9 years now I think. I was told that the longer/slower you wean the more your breasts get a chance to fill in with more breast tissue. But I have been a D to DD cup since beginning my BFing journey all those years ago. But Haven't had a chance to see what will be come of them yet LOL. I was a small 12 b before kids.

eta - On to my 5th child & I must say, I am impressed with my breasts LOL they are holding up well.
