When you have sore nipples, the last thing you want to do is put a shirt or a bra on and have anything rub against them. These are a lifesaver!!! I used them with my sore nipples and it really helped. It keeps all clothing off of your nipples, and has air holes allowing your nipples to breathe. The other nice thing about them is that they actually catch milk in case you have a let down (since you can't wear breast pads with them). One thing though - make sure you don't bend over if there is milk in them; the milk will come out of the air holes and get your top all wet!
