Baby refusing to latch

Kay • After four miscarriages, I'm enjoying my perfect little rainbow girl and now her perfect brother.
We had a good system down for a few feedings, but now my newborn pitches a fit and gets all worked up when I try and feed. She calms down after a few minutes (like 10) and then nurses okay, but any suggestions to help calm her when we begin the feeding? I feel horrible and I can only do so much with my boob hanging out to try and calm her.
