Hm. Can you move her crib into your room for a while, so you're still near her? Then eventually move her back to her room? (If you already share a room then I'm at a loss.)
I assume you've tried noise machines? Food right before bed for a full tummy? Regulating liquid intake to reduce the chances of a full diaper in the middle of the night? Dressing her warm or cool enough? Changing nap schedules?
