ETA - Good point, Marda...

Bless your hearts - this is tough. I wouldn't put her in bed with you, to be honest. I think you might trade one problem for another one and none of you get decent sleep.
What is she doing during the day? Is she napping during her usual times, or is she crashing? Or, is she not napping either? If she is over-tired from not napping during the day, it could be messing up her night sleep. If she's sleeping too much during the day, it could do the same thing. Hard to find that balance...
Since the doctor has cleared her, as hard as it may be I'd let her do the whiny cry until she calms herself down and sleeps. Try to keep her on her regular sleep schedule even though she's having trouble. I think that may be the best way to get her through this. Best of luck~~~
