Can you rule out more of these listed in this article?10 reasons (other than hunger) a baby can wake at night
The separation anxiety pops out at me. I'm sure you realize that the more often you feed her, the more likely it'll become a habit. Certainly attend to her at the NW, but try another technique and be consistent. What else have you tried? The paci doesn't work if held her and gave it to her?
For night terrors, there's a technique some people have had success with... it's described below. I think most people use this when it's more frequent. From my experience, my son had them when he was too warmly dressed. Having a fan at the beginning of the night helped, too.
"For a few nights (weeks if they are not that frequent) write down at what time the terrors start. You will normally discover a certain pattern and a time slot in which a terror typically occurs. Then, for a few nights (even if you are not sure there will be a terror) gently wake up your baby about 20-30 minutes before that time slot.
Sit up with her for a few moments, talk to her softly and then put her back down to sleep again. If she is not easily awakened like this, you can try changing her diaper but avoid 'too exciting' activities or it may be difficult to get her back to sleep again ...
This short wake time can help change her sleep pattern and that can avoid the confusional arousal after a while."
