I would be careful about block feeding. I am lopsided because I prefered one side more without knowing I had to spend equal time on each side. What I do now, is nurse on big side until letdown, then switch until squirting stops, then switch again. yes, for me, it has always been like this and has not changed. I'm just past the 7 month mark, too. FYI- I bottle feed in public because it's easier than dealing with the mess of milk and more importantly, the frustration for my little one. hope this helps a little.
