4 week old dd has a very bad latch and I just can't seem to improve it. I'm in agony, she's starving. Already given two bottles today so worried about supply. I'm sat here with her screaming next to me to upset to even latch on badly. I hate breast feeding but feel terrible at the thought of giving up. Can't produce more than 1oz milk when I express. How can I get through the night?????? Scared I'm getting so upset I might hurl her across the room...
