I tend to do each feed from one breast only, alternating them between feeds. DS gets as much as he seems to want from one breast, bringing himself off and settling well afterwards, and he's put on plenty of weight so this seems to be okay milk-wise.
However, he's always disliked feeding from my right breast, I think it's because he favours his right side and has to turn the 'wrong' way for it. It's always been a struggle but recently (DS is eight weeks) it's become almost impossible to get him to latch on that side, and when he does it's normally really painful.
We introduced him to bottles a couple of weeks ago, so he tends to have one bottle of EBM every day, and we always use it to replace a right breast feed. I was starting to wonder if I could just start replacing all the right breast feeds with expressed bottles. Would there be any problems with that? His struggles with it are really making me start to hate breastfeeding, especially at night
