Just read your post above and it sounds like you are in pain for entire feed. This didn't happen to me as the pain would subside as the feed progressed. I'm so sorry you are going through this it is just awful. Takes the edge of the new bub experience that's for sure.
Look after yourself and your boobs. Just do whatever you need to do!
But when they say that if bub is attached properly it shouldn't hurt... well I find that hard to believe because in those initial weeks it just hurts like hell for me and the attachment is fine!
It's so hard...
