Hi T.,
I have a daughter who had night terrors at that age. They started at 18 mos. and she is now 7. She still has them occasionally but at age 3 they were much more frequent. I'm not sure if your daughter is having chronic night terrors or just a few bad nights. Here's what I learned about night terrors:
I couldn't wake her up, nor are you supposed to. I would take her downstairs away from earshot of our baby and just hold her until the crying stopped. She made very strange crys and had some jerky motions. It can be very scary since they are acting like aliens! Eventually she'd calm down and be calm enough to go back to sleep but it took up to 30-45 min. sometimes. I just got to the point where I wouldn't let it bother me and told myself "this will stop soon." She never remembered the incidents in the morning and it didn't seem to affect her. I was always tired the next morning of course.
I did search the internet for solutions when they were happening often. One theory which I tried is waking them up around 4 hours after they've been asleep. This did work for awhile but she went back to them again. She has now pretty much outgrown them but now sleepwalks occasionally which I believe is related.
One other note: We now find her sleepwalking coincides with her having to use the bathroom. Ask you daughter or help her sit on the potty if she wakes up crying. It could be that the urge to go wakes her up but not all the way. Good luck!
