Here are more details on my situation: I am unfortunately working full-time and can be gone during the day up to 12 hrs. She tends to "expire" around 6 or 7 at night and can be inconsolable if I'm not home to nurse, even refusing pumped milk from my husband (I know, my heart breaks - my commute is over an hr each way - but that's another story!) I also "nurse-down" and up to a few times during the night, on average. And like I mentioned, we're co-sleeping and she is "high-need" (ESPECIALLY at night!) My husband is able to occasionally put her down at night without nursing (and VERY rarely can get her back to sleep if I'm at home but not in bed) and she's also able at times to fall asleep during the day without the bottle, usually in her swing. Last month I was gone overnight and my husband said she awoke 3 times during the night - the first time she needed a bottle and the next 2 times she was able to fall asleep w/ "Sssshhhhing" and back-rubbing. However, they were camped out in the living room and not in the usual nursing environment - our bed. I've found that I myself can get her to sleep with music and motion on the rare occasion that she's overtired and won't settle down to nurse.
Any guidance from experts out there would be so helpful Thank You!!!!
