To answer your SWH question, cut out both of the feedings at the same time, S.. She has to understand that the night bar is closed.
If you cannot bear to let her cry it out for a week until she stops waking for your nursings, then ask your husband to go in when she cries, pat her on the back for a few seconds, walk out and add 5 minutes to the clock each time. So, in 5 minutes, then 10, then 15, then 20, etc. You have to REALLY watch the clock. She may cry for over an hour for a few nights, but then she will finally sleep through the night. OR, tell him to go in and sit on the floor beside her crib and put his hand between the slats and touch her leg. She will want to be closer to him, so she will lay down in the crib and cry. He should do NOTHING ELSE. No patting, no talking, no holding, no picking her up. Just sitting and touching her leg. She will cry. No matter. She has to learn that night time is different than daytime. You ALL will finally get sleep and you won't end up losing your job from fatigue or ending up with extreme exhaustion.
Your husband has to be 100% consistent. If he gives in and picks her up and changes the minimal contacct, it encourages her to stay awake and wake herself up. She needs to learn to self-soothe. Tell him that the reason that HE needs to do this instead of you is because she knows YOU are all about milk. It will make it much harder for her to settle while she is smelling you and your milk. It's fine for you to nurse during the day around your work hours. However, he needs to do this for you both.
Original:
She doesn't need a feeding in the middle of the night. Stop feeding her. That is your major problem.
