Help! I've been expressing every morning so that DH can give DD (3 months) her 10pm feed and I can go to bed early. I've been getting 4oz without too much bother, but suddenly I'm struggling to even get 2oz. DD needs more like 5oz at the last feed and so now I'm trying to decide whether I should stay up and BF myself, or give her formula at the last feed. Don't really want to introduce formula yet, but equally, not sure I can get by on less sleep than I'm getting already. I don't understand why my milk supply has suddenly reduced as DD's feeding pattern hasn't really changed. Any ideas?
