Hun, I'm sorry to hear that you are still having so much pain I think you are really amazing for putting up with the pain for so long. That is really courageous. Making the decision to formula feed is totally understandable and you shouldn't feel bad for making the decision that is right for you and your family. At this point you can make that decision knowing that you did all you could to bf for as long as possible, and that you put up with a lot of pain to do so. That is really something to be proud of, and I hope it is enough for you to be able to switch without guilt.

All the best hun
