I have a nasty case of thrush and this combined with some positioning issues have caused my poor nipples to become cracked, bleeding etc, one is split from one side to other. So every time I feed DD they are opening up again. She is sicking up blood and feeding is now so painful I can't cope much longer. I don't want to give up BF so it has been suggested that I give her some formula for a day or so, and express at same time to keep up supply, in order to let nips heal. Expressing still hurts but is better than those hard little gums. Any thoughts as am at the end of my tether ???
