Like many people (I believe), bf-ing can make me slightly, shall we say, lop-sided! My right boob, when full of milk, is noticeably (to me at least) bigger than my left. It's also been the more "spurty" of the two as well : it has been known - when DD pops off mid-feed to gawp about - to spurt from 5 points! (Does everyone else have that too?).
Anyway, although I do try to swap at each feed, I know that I favour mega-boob, in some vain (both senses!), vicious circle attempt to get it the same size as normal boob (temporary success only).
My DD is nearly 9mo, and we've had a lovely, smooth time of bf-ing, pretty much, so bf-ing is well established now, I think. And she certainly doesn't seem to find normal boob less satisfying than mega-boob. But is my blatant favouritism of mega-boob going to cause me problems? I intend to bf until DD self-weans.
TIA!
