I moved up to an F cup when I was feeding and it frustrated the living daylights out of me! Friends that had smaller boobs seemed to be able to feed a lot easier than I did (and they had a better supply too!).
I tried many, many things to help my supply (maxalon and fenugreek tablets, frequent feeds - like, every hour :roll. I also tried different ways of attaching the baby.
Either way, I always felt far more exposed (you get used to it though) and I couldn't see Gabby's face to know if she was breathing ok or not.

In saying all of that, I really did start to enjoy BFing and I was very sad to give it up when I did. I am hoping that next time around, it will be a whole different kettle of fish!
