Why would it be nursing all night long if she is only waking at 11/12 and then again at 4/5? Thats 2 feeds. She may need them (growth spurt, comfort etc)
Personally I would do the 2 feeds, in her room then put her back in bed.
But if thats not what your looking for then I dont have advice. Seems your only option then is letting her cry it out.
