I am rea struggling with night feeds at the moment due to pain from poor latch due to tongue tie. It's easier/less painful to feed in the day time and I'd like to swap to formula at night. My ds is only 10days old so I feel swapping now would cause a problem with my supply. I can't bear the thought of feeding her and expressing in the middle of the night yet as she takes ages to feed and its excruciating etc. When will my supply be established enough to swap to formula night times only? this makes me feel awful because I want to nurse her all the time and if I go to combi feeding I'd rather ff in the day ao we can be more flexible with my toddler etc.
